Page 10: Installing The Console
Installing the Console The GL2400 has a space saving, compact chassis design. This is convenient both in saving seats for the paying audience in a busy venue, and in reducing the size, complexity and weight of flight casing for on-the-road use. The control surface has a 10 degree slope for optimum visibility during operation. -

Page 13: Audio Connections
Audio Connections The GL2400 uses professional grade 3 pin XLR and 1/4" TRS (3 pole) jack sockets. To ensure best performance, we recommend that you use high quality audio cables and connectors, and take time to check for reliable and accurate cable assembly. It is well known that most audio system problems are due to faulty or sub standard interconnecting leads. -
Page 14: The Console Connectors
4pin XLR sockets to plug in standard 12V gooseneck lamps to illuminate the operating surface when working in a dark environment. Only use lamps intended for this purpose. We recommend the Allen & Heath LEDlamp with cool white LED illumination and a built in dimmer. GL2400 User Guide... -

Page 16: Mono Input Channel
Check that you are using the best microphone type and placement before using the EQ. Start with the EQ set flat and apply only as much boost or cut as is really needed. When dealing with problem frequencies cut rather than boost where possible. GL2400 User Guide... - Page 17 LR mix, groups and post-fade aux sends. It also affects the direct output if this has been set to post-fade using the internal option jumpers. The fader provides +10dB maximum boost above its normal unity gain 0dB NOISE position.

Page 18: Stereo Input Channel
The STEREO Input Channel Each GL2400 stereo channel features a mono microphone preamp +48V as well as two stereo line inputs. These three sources can be used independently or mixed together into the channel, so providing a GAIN unique flexibility. For example, you could configure a conventional mono microphone channel with the two ‘‘short return’’... -
Page 19: Group/Aux Masters
A 100mm smooth travel fader controls the group mix output level. Note that it becomes the aux mix master in monitor mode (REV pressed). The fader provides +10dB maximum boost above its normal unity gain 0dB position. GL2400 User Guide... -
Page 20: Aux5-6, Lrm Masters
MUTE The M output adds a true touch of genius to the versatility of the GL2400. The source is selected using two mode switches above the R fader. These are recessed to prevent accidental operation. Use a pen or pointed object to set the position. -
Page 21: 7X4 Matrix
7x4 MATRIX The matrix adds to the powerful multi-tasking capability of the GL2400. It provides a set of 4 additional console outputs. It is a ‘‘mixer within a mixer’’ creating its output from any combination of the groups, main LR mix and external input. It can be used to provide duplicate main outputs or to create new mixes from these outputs. -

Page 24: Using The Oscillator / Noise Generator
Testing a system with pink noise through the speakers is often referred to as ‘‘pinking the room’’. The GL2400 signal generator is an invaluable tool for calibrating and testing the system during setup. To prevent any unexpected mishaps during the sound check or show, remember to disable it by releasing the recessed ON switch once you have finished the testing. -
Page 25: Using Pfl / Afl
We recognise the importance of correct gain structure and signal handling. The GL2400 includes LED meters for every input channel and main output, as well as a pair of high resolution meters dedicated to monitor duty only. -

Page 28: Applications For The Matrix
One way to do this is to feed the PA from a pair of matrices, and then use EXT Inputs to combine the external console with the main LR mix. GL2400 User Guide... -
Page 29: Create Iem Mixes With Ambience
You could also add in ambience as described above to give the recording more life by including audience reaction and natural reverberation. Recording with the GL2400 The console is equally at home recording live or in the project studio. -

PA. Typically the LR (tops) use fader masters, and the aux is on a rotary master. The GL2400 overcomes this with an innovative mode GL2400 switch above the master faders that routes the AUX6 mix master through the M fader and on to the XLR output. -
Page 31: Using The Channel Direct Outputs
You can use a ‘‘Y’’ splitter cable or adapter to feed one output to two destinations, but never try to combine two outputs to one destination. This may damage or degrade the performance of the equipment driver stage. GL2400 User Guide... -
