around 0 dB on the Main Mix meters , provided that both channel and output level controls are set to unity
gain (0 dB).
4.2 Equalizer
The EQ is in principle identical to that on Mono Channels (see 3.2), except that the EQ is stereo, of course!
A stereo equalizer is generally preferable to using two mono equalizers when EQ-ing a stereo signal, as often
discrepancies between left and right settings can occur.
4.3 Aux send
It is the same as for Mono Channels (see 3.3). Note that a mono sum is taken from the stereo input.
4.4 Volume control and panning/balancing
The only difference here from the Mono Channel described in 3.4 is in the implementation of the Balance
Control . When a channel is run in stereo, this control determines the relative balance of the Left and Right
Channel signals being sent to the Left and Right Main Mix buses. For example, with the Balance control turned
fully clockwise, only the right portion of the channel's stereo signal will be added to the Main Mix.
If a Stereo Channel is run in mono (only the left input connected), the Balance control acts as a pan in the
normal way.

5.1 Aux send
This is on a 1/4" unbalanced jack at +4 dBu. No master Aux Send Level pot is provided. However, you can use
the input level control of your effects unit to match the output level from the EURORACK. If your effects unit
does not have an input gain, then remember that every Channel Aux Send has up to 15 dB gain, which should
be more than enough to drive any effects unit.
5.2 Stereo Line Input
Aux return
If only the left socket has a jack connected, the Aux Return operates in mono and is permanently assigned to
the Main Mix.
2-Track in/output
This unbalanced Stereo Line Input incorporates a flexible routing system.
When the switch 2TK TO MIX is depressed, the input is assigned to the Main Mix, like the Aux Return.
Use this configuration when you need to create extra Line Inputs for MIDI keyboards etc.
However, with 2TK TO CONTROL ROOM depressed, the input is now assigned to the Control Room
output. This routing mode enables off-tape monitoring of a stereo recording to be effected at the flick of a
switch.
5.3 Metering
Main Mix level is displayed on a pair of accurate 4 segment bargraph Peak meters . Two further LEDs
indicate Power On and +48 V DC Phantom Power present .
The Main Mix bargraph meters should average around 0 dB during loud passages. If they read persistently
higher, or are peaking above +22 dB (PEAK LED of the display) reduce the level. When both the Main Mix
