Speck Electronics Xtramix - Manual (Page 8)

To avoid personal injury, do not remove the top cover from the power
supply, or the rear panel of the Xtramix and never operate the external
power supply without the cover properly installed. If it becomes
necessary to remove the rear panel of the Xtramix for service, always
unplug the AC power and disconnect the DC interface cable before
proceeding.
The Xtramix is a high performance line audio mixer that may be used
separately or as part of a larger mixing system.
When used as a rack mount recording mixer, the Xtramix provides 40
synth inputs (20 stereo inputs), 8 subgroup assign capability, and the
ability to access up to 8 stereo effects devices. A complete 8 x 2
monitor and mix section allows the input channels and effects channels
to be mixed to the stereo program, monitor and headphone outputs.
When used as a traditional synth/sampler mixer the Xtramix has the
ability to be operated in many configurations. It may be used as a 70
input, 2 output compact keyboard mixer; or as a 56 input, 8 subgroup, 2
output keyboard mixer; or as a 40 synth or line input, 16 subgroup, 2
output mixer; or any combination of the above mentioned
configurations.
The mixer is divided into three basic sections. The input section, the
effects send and return section, and the master section.
The input section consists of 20 stereo input channels and has all the
controls necessary to effectively control synth and sampler operation.
Channels include level control with 8 subgroup assign, a pan/balance
control, 2 effects sends that are assignable to 8 effects busses, and the
ability to solo the signal. The rear panel for each input channel offers
balanced 1/4" TRS connectors for synth or line interface, an effects
stereo/mono select switch, and a low/high input level select switch.
The effects section provides total control for up to 8 stereo effects
devices.
Each of the effects channels include an effects send master for its
respective effects buss and associated effects sum input. The effects
return includes a stereo effects return level, 8 subgroup assign, pan, in-
place solo, and mono select switch. Each effects channel has a 1/4"
TRS send jack, a 1/4" TRS effects sum in jack, and (2) balanced 1/4"
TRS jacks for the left and right effects returns. Do not remove covers or panels
