Recent expansion of the facilities at the Ulsan Galilee Church in South Korea have seen the opening of a new building housing an 800-capacity main worship area, seminar rooms, library and café, for church members and the local community. Supplied by local distributor Sama ProSound and installed by Daiyoung Sound, the church requested a separate monitor system for singers and band members, so Daiyoung Sound Director Joon-ho Choi selected Allen & Heath’s GLD digital mixing system, ME-1 personal monitor mixer and Qu-16 compact digital mixer for the task.

Ulsan Galilee Church‘The combination of GLD and ME was the most attractive option,’ he confirms. ‘The GLD’s I/O remote audio racks mean the system is scalable to manage all requirements. The mixer also has great audio quality, an intuitive interface, and a wonderful custom layout design. ME-1 has the most monitor channels in the personal monitor market, and the group option, ambient mic, dedicated monitor output port, which means an option card is not needed, are the reasons why I chose the system for the church, whilst also saving budget.’

It took a year to complete the project, five months of which were dedicated to installing the broadcast, audio and cabling. At first, the church had doubts about installing a digital system since it had not used one before and does has few experienced audio engineers on staff, but the GLD Remote iPad app and GLD Editor control software, exceeded expectations.

The system is set up to enable control at FOH position and in the control room at the same time. The GLD-80 mixer is installed at FOH with the AR audio racks at the side of the stage connected via single Cat5 cable, reducing the wiring budget. ‘The musicians were very happy with the monitor system, especially the ME-1 personal mixers, which they say deliver excellent audibility and allow them to focus on their playing,’ says Mr Choi.

A Qu-16 compact digital mixer is installed in the control room to manage all recording, playback and broadcasting. It was selected because of its motorised faders, scene recall, and it has the most I/O in its price range. ‘Qu-16 has both a Touchscreen and motorised faders, which most other competitive mixers don’t have. It was the main reason that the church accepted it. Of course, USB recording functionality and high audio quality were very attractive points as well,’ he adds.


{jcomments on}CDC EightRichard Ferriday and James Godbehear are in agreement – while their recent move from Midas to Cadac took the industry by surprise, it also presented them with something of a culture shock.

‘We’re now in a place where our contribution can make a difference to what goes on,’ Ferriday says. ‘It’s nice to be back in a position where you can make decisions and live or die by them.’

Sennheiser’s Digital 9000 digital wireless system addresses broadcast, theatre and live event applications.

Digital 9000 digital wireless systemThe SKM 9000 uses an 88MHz switching bandwidth, and is available in black and nickel. Command switch versions for easy communication between broadcast units or artists and their crews are also available. As the handheld transmits digitally, it does not employ a compander and is exempt from the associated noise. Digital 9000 includes the EM 9046 receiver, SKM 9000 handheld and SK 9000 bodypack transmitters, plus a suite of accessories.

‘This system is offers unprecedented sound quality and ease of use,’ says, Wireless Microphones Portfolio Manager, Kevin Jungk. ‘For example, users will no longer have to calculate and circumvent intermodulation frequencies but can conveniently place their transmission frequencies in an equidistant grid.’

The system supports two transmission modes –High Definition (HD) mode will transmit entirely uncompressed, artefact-free audio, ‘as if a high-quality cabled microphone were used’, while Long Range (LR) mode is designed for difficult transmission environments, offering maximum range with a proprietary Sennheiser digital audio codec.

In addition to IR synchronisation between receivers and transmitters and a antenna loop-through for creating larger receiving systems, Digital 9000 claims a number of unique features. The high linearity of the entire system eliminates intermodulation calculation, allowing transmission frequencies can simply be set in an equally spaced grid. The receiver also automatically measures RF cable loss between receiver and booster, and adjusts the gain accordingly.

The modular EM 9046 receiver is a mainframe that accommodates up to eight receivers internally.

EM 9046 Receiver

A large display with clearly laid out controls is at the heart of the EM 9046 receiver. Three display modes ensure that the RF or sound engineer has an overview of important parameters in live situations and can change settings quickly via an intuitive, icon-based menu. Channels can be monitored via the headphone output, either individually or any number can be listened to combined.

The receiver system covers the UHF range from 470 to 798 MHz (328MHz bandwidth). To integrate the system into an existing infrastructure, users choose between transformer-balanced analogue or digital AES3 audio output modules, or a mix of both.

System set-up is facilitated by a built-in graphical spectrum analyser to scan the RF landscape, and an RF level recorder for checking reception and optimising antenna positions. The receiver will also suggest the best transmission mode for the environment being worked in, and will automatically set an appropriate gain to counteract RF cable losses. The antenna boosters can be controlled via the receiver, which is helpful for installations with remote antenna positions.

The multi-channel receiver and the transmitters can optionally use encrypted data transmission, with proprietary keys generated randomly. This will protect a radio link against hijacking and tapping.

The receiver stores up to ten complete system configurations so that set-ups can easily be recalled and repeated.

SKM 9000 Handheld Transmitter

The SKM 9000 handheld transmitter is compatible with all of Sennheiser’s evolution wireless G3 and 2000 Series microphone heads, including the Neumann KK 204 and KK 205 capsules. Besides these capsules, the handheld can be fitted with four dedicated 9000 Series capsules.

‘The 9000 Series would not have been complete without the sound of our most successful live capsule, and I am happy that the cardioid dynamic MD 9235 is part of our new digital system,’ Jungk says.

The MD 9235 is complemented by the transparency of three permanently polarised condenser mic heads, the ME 9002 (omni), ME 9004 (cardioid) and ME 9005 (super-cardioid). The condenser heads feature a low sensitivity to pops and have extremely low handling noise due to snowflake-shaped rubber suspensions above and below the actual capsules.

SK 9000 Bodypack Transmitter

The SK 9000 bodypack transmitter comes in a magnesium housing that combines robustness with low weight. It can be used with any clip-on or headset mic with a 3-pin Lemo connector and has a line input for guitars or other instruments. ‘As the system is able to deliver cable-like audio, we have added a three-step guitar cable emulation to round off the instrument sound,’ explains Jungk.

The SK 9000 is available in four different frequency ranges (88 MHz switching bandwidth); a command switch for communication between crews and artists/reporters is available as an accessory. To protect the system against interference, the AB 9000 antenna booster has been fitted with eight highly selective filters to allow just a specific frequency window to pass. Unwanted signals are thus blocked before the first active component, adding to the overall reliability of the system. The filter can be set manually on the booster or remotely via the antenna cable on the receiver.

The AB 9000 provides a maximum gain of 17dB and is available as a standalone booster or integrated into the A 9000 omnidirectional antenna and the AD 9000 directional antenna. Two booster versions (470-638MHz and 630-798MHz) cover the receiver’s UHF range.

The transmitters of the 9000 Series operate on environmentally friendly lithium-ion rechargeable battery packs, with a precise remaining operating time indicated on the handheld and the bodypack transmitter as well as on the receiver. The SKM 9000 is powered via the BA 60 rechargeable battery pack, which will power the transmitter for 5.5 hours. The SK 9000 bodypack is powered by the BA 61, which lasts for 6.5 hours. Operation on standard batteries is possible too.

The L 60 charger will recharge two BA 60 or BA 61 in any combination. It reaches 70 per cent of charge in an hour and full charge after three hours, with the charging status being indicated by three-colour LEDs. Up to four chargers can be daisy-chained and powered via a single power supply unit.

‘Spectrum is a scarce resource, therefore every part of the system has been designed for the highest frequency efficiency,’ Jungk says. ‘We have put much effort into allocating the largest possible data rate to the actual sound transmission, ensuring the unmatched audio performance of Digital 9000.

Dante Controller v3.5Audinate has released Dante Controller v3.5, an update to its free networking management configuration and monitoring application.

New features add advanced real-time network monitoring functionality, including multicast bandwidth use, clock health monitoring and latency management statistical information. These provide quickly identification and rectification of potential issues on a network, while preserving Dante Controller’s ease-of-use.

‘Many of the new features in Dante Controller 3.5 were implemented to directly meet specific customer requirements’, says Audinate VP of Product Management, Gary Southwell. ‘Dante Controller 3.5 includes many features that AV and IT professionals could only dream of a few short years ago.’

Key updates:

Enhanced Latency Reporting
·  New histogram-based reporting and tracking of transmitter latencies – provides at-a-glance information about the latency performance of audio flows for supported devices.
·  Latency histograms indicate if latency play-out settings are properly configured, and also provide an overall view of the health of the network: allowing an operator to quickly see if an audio flow has been properly configured and if underlying network issues could potentially develop into an audio quality problem.
Improved Clock Health Monitoring
·  Clock health is now tracked on a per-device basis via dedicated performance histograms. This enables the quick and easy detection of difficult-to-diagnose network issues, which are impacting clock accuracy - such as clock traffic bottlenecks, and low-performance external word clocks.
New Preset Tool Suite
·  New preset system exposes XML-based network configuration presets for use in off-line configuration tools. This simplifies the setting up of new networks, and the reconfiguration of existing networks.
·  Presets enable simpler switching between standard configurations and special event configurations. Provides greater confidence in the ability to share audio network configurations for multiple uses and/or user groups.
Redundant Network Connection
·  Enables visibility of primary and secondary networks at all times. Redundant devices can still be seen and managed via the secondary network in the event of a problem with primary network connectivity.
·  Simplifies redundant network set-up, and allows verification of network configuration.
·  Provides real-time notifications about connectivity status on both primary and secondary networks.
New Channel Grouping Capability
·  Allows simple viewing and configuring of large numbers of device channels, in groups of 16.
·  Each group can be expanded then collapsed when set-up is complete.
Improved Network and Device Status Information
· Network and device information has been enhanced and restructured across two tabs (including a new Network Status tab) to provide a clearer and more useful overall picture of the network.
· New notification icons provide real-time information about a range of network and device events.


Roland Systems Group has released an iPad app for its M-300 digital mixing console, providing parameter control, as well as additional practical features such as the ability to store scenes and edit the Channel Strip (EQ), GEQ and Sends on Fader.

Connecting the Roland Wireless Connect USB adaptor to the M-300 USB port links the M-300 to a wireless network, allowing the iPad can connect to and control the desk from different locations within a venue. As well as ease of use and mobility, this dual screen set-up can also be used by a radio mic tech to check and monitor each microphone as they are handed out during a live performance.

Roland M-300 iPad control‘The success of the iPad as a tool in live audio applications is clear,’ says Simon Kenning, Sales Manager for RSG UK. ‘This dedicated M-300 app builds on the success of the M-480 app released last year, and is an important addition to our range of remote control applications.’

Alongside the iPad app, Roland has also announced v1.5 Firmware for the M-300. This free update brings features such as a 31-band mono GEQ, new effects for the effects library, audio crossfade for scene changes and a detailed Recall Filter function. A Channel Display screen has been added for DCA groups, as well as the ability to disable more user settings and a default guest start-up mode feature.

Enhancements to the monitoring function include a dimmer function and a lock-out feature that disables the Level knobs to prevent any accidental monitor volume changes. The v1.5 upgrade also provides additional RS232C commands, improving the control parameters and ensuring that system installers, integrators and users have access to more remote control functionality from touch panels, video devices, and software.

Concurrent with this update is the announcement that all V-Mixers now include the ability to do multichannel recording by simply connecting a Cat5e/6 cable from any REAC port to a network port on a PC to enable 40 channels of WAV capture.

DiGiCo has announced a new version of Optocore for all of its optically-enabled digital mixing consoles.

Marc BrunkeThe new format will provide connectivity to X6R, DD2FR and DD4MR units, allowing Optocore devices to live on DiGiCo’s optical loop. Users can now add a simple Optocore  interface to the DiGiCo network to provide additional I/O connectivity, together with Ethernet and RS485/422. They can also use Optocore  DD2FR-FX and DD4MR-FX Madi interfaces to increase the number of Madi ports available on the console.

‘By adding a simple 16-channel Optocore X6R-FX interface to the DiGiCo network, extra I/O can be achieved together with Ethernet and RS485/422,’ confirms Optocore founder, Marc Brunke.

Although Optocore partners with multiple console manufacturers, only DiGiCo has OEM Optocore and is running the native 2.21 Optocore protocol. ‘With both companies' R&D departments working closely together, we have managed to join two systems together in an intuitive and elegant way,’ Brunke says.

‘This complete, cost-effective solution provides the bridge between low-channel-count and high-channel-count devices,’ Brunke adds. ‘Until now, Madi has been too expensive for low channel devices but this is no longer the case. Also, because the new version makes Madi compatible with IEEE802.3, it can now be used in combination with other recent network standards like AES-X210 / AES-67 or older proprietary Ethernet implementations.'
