4.2 Stereo Aux-Returns
There are two additional stereo line inputs (Aux Returns 1 and 2) on your MX802A. Their level can be adjusted
with and . Aux Returns 1 is permanently assigned to the Main Mix. If you connect a jack only to the
left socket, the Aux Return 1 operates in mono. Aux Return 2 can be switched between the Main Mix and the
cue feed (Aux Send 1) via a switch marked FX TO AUX 1 . This enables you to provide a wet cue mix
(signal with effect i.e. reverb) for the headphones or foldback speakers.
If no connection is made to Aux Return 2, the signal is normalled (connected directly) to Aux Return 1.
Depressing FX TO AUX 1 will then feed the signal from Aux Return 1 into the cue feed (Aux Send 1) and can
be controlled in level independently with Aux Return 2. This feature is primarily useful when you are using one
effect for the main mix and for the foldback speakers.
+ When using Aux Send 1 as a second (pre-fader) effects send and Aux Return 2 as the effect
input, do not engage FX TO AUX 1 . The connection from Aux Return 2 to Aux Send 1 could
cause feedback.
There are exceptions. For instance, when you want to send one effect into another, e.g. delay into chorus etc.
+ Sometimes an engineer wants to narrow the stereo width of a reverb field. To do this you will
have to come back on two mono channels to get independent Pan for the left and right sig-
nals.
4.3 Metering
Main Mix level is displayed on a pair of accurate 12-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 +10 dB (top segment of the display) reduce either the Main Mix volume and/or the
channel volume, or (as a last resort) channel input gain or instrument / FX unit output level.
4.4 2-Track Input / Main Mix Output
Input
A 2-Track input, on RCA phono jacks , provides easy connection to DAT and other professional and
semiprofessional audio equipment. The 2-Track input is primarily for auditioning mix playback from tape.
Switch 2TK TO CTRL ROOM routes this signal to the studio monitors. However, it can also be routed to
the Main Mix via switch 2TK TO MIX. Here should be disengaged, or you will be listening to the 2-
Track signal twice over! With depressed you have another stereo line input available to the mix.
+ The 2-Track input could be normalled to the output of a HiFi preamp, allowing you to moni-
tor extra sources such as vinyl, cassette, CD etc.
Output
A single pair of electronically balanced TRS jacks deliver the Main Mix output to your 2-Track recorder (or
PA system). RCA phono jack outputs are also provided for easy connection to DAT, cassette desk etc.
Level is ultimately determined by a precision Main Mix volume control .
4.5 Monitoring
The MX802A has a separate headphone output . The phones signal follows the control room output .
A single volume control sends the level to the headphones and main monitors.
The L/R meters follow the Main Mix.
