Page 5: Introduction
Each Stereo Return has 3-band EQ, 2 AUX sends, full Sub-group assignment, 60mm high quality fader and solo system. - FULL TALK-BACK SYSTEM Talk-Back assignment to AUX, Groups, MIX outputs can be selected. Matrix outputs have Talk-Back enable switches. IMX-824/832/840... -

80Hz and 12kHz respectively. Its two bell-response MID bands are semi-parametric, meaning that the center frequency of the curve can be varied. The IN switch inserts all four bands into the signal path, which is useful when checking the effectiveness of your EQ settings IMX-824/832/840... - Page 7 If, for example, you are panning from hard left to center, you will notice a 3dB drop in the left channel as you do so. This “panning law” ensures that signals sound equally loud at all pan positions. IMX-824/832/840...

High Mid and Low Mid bands have a bell response centered around 3.15kHz and 315Hz respectively. The IN switch inserts all four bands into the signal path, which is useful when checking the effectiveness of your EQ settings. IMX-824/832/840... - Page 11 Similarly, with the balance control set to hard right only the right signal will be sent to even numbered buses. If, for example, you are panning from hard left to center, you will notice a 3dB drop in the left channel as you do so. This “panning law” ensures that signals sound equally loud at all pan positions. IMX-824/832/840...

A professional 100mm fader gives you smooth, high re- solution control over the sub-group level. 7. AFL Connects the sub-group’s Post-Fader signal to mono AFL bus. You can monitor the signal on your phones and the AFL BAR METER. IMX-824/832/840... - Page 15 IMX-800 SERIES allows either the Aux or Group outputs to use the long-throw faders and inserts. This is done for each output using the FLIP control. Please take care when using this control, as the physical output and insert sockets are also affected by your selection. See above for more details. IMX-824/832/840...
- Page 16 In normal operation, the top XLR connector is the output for the Auxiliary bus, while the lower XLR and INSERT jack are for the Group signal. When the front panel “FLIP” switch is activated, the signals to the connectors are swapped. IMX-824/832/840...

2. MUTE Mutes the After-fader signal of the channel path. Pre-fader signal, which provided to Matrix-PRE path is NOT affected by this switch. 3. MASTER FADER A 100mm stroke fader adjusts the channel signal level continuously from to +10dB. IMX-824/832/840... - Page 18 SOLO or AFL button is activated. 5. MATRIX MASTER - MASTER LEVEL: The Matrix master level ranges from +10dB. - AFL: Connects the MTX output to monaural AFL bus - TB: Connects talk-back signal to MTX output. IMX-824/832/840...

Page 20: Efx Return Input
The PK lamp warns of signal levels approaching the upper headroom limit, which means about 3dB to the clip point. We recommend that you reduce the source’s output level to avoid nasty clipping! 8. BUS ROUTING Connects the channel signal to each of the GROUP and MIX buses. IMX-824/832/840... - Page 21 1. L / R INPUT A pair of 1/4” TRS jack sockets allow balanced input. Nominal input level can be selected by a level switch on the RETURN section as -10dBv or +4dBu. Input impedance is about 10k ohms. IMX-824/832/840...

6. DESTINATION Selects destination for both the tone generator and the talk- back circuit. 7. TALK BACK This sends the talkback mic signal to the outputs selected in the above routing section. This switch is a PTT (push-to-talk) momentary pushbutton. IMX-824/832/840... - Page 23 Use only stereo phones! When a mono connector is plugged into the stereo connector, it connects both sides of the headphone amplifier to a single load.
