Description
Features of the system
• In addition to the main stereo outputs, this mixer provides six AUX outputs plus four group outputs (a total of 12 outputs). The AUX/GROUP outputs can be used not only as sends to external effect processors or to a multitrack recorder, but are also ideal for creating separate foldback mixes for each speaker and amp.
• The MONO OUT jack can be controlled independently from the STEREO OUT jacks. Since a monaural mix of the main output is sent from this output, it can be used to extend a PA system.
• All input channels provide a high-pass filter, a three-band EQ, and 60 mm faders.
• All input channels/AUX returns provide a PFL switch, and AUX/group/stereo output channels provide an AFL switch. You can audition input and output sources at the touch of a button.
• All mono input channels provide balanced XLR type and TRS phone jack connectors that accommodate a range of sources from mics to line level devices.
• Switchable phantom power is provided. This can supply DC +48 V power from the XLR type input connectors to condenser mics and direct boxes that require an external power supply.
• Two stereo input channels allow connection of line-level equipment. 1/4" phone jack and phono jack inputs can be selected by a switch.
• Two stereo AUX returns are provided. This allows AUX return signals to be sent to an AUX bus or GROUP bus as well as to the ST bus. These can also be used as spare line level input jacks.
• An insert I/O jack is provided on each mono input channel and on the ST bus, allowing you to insert external effect processors as desired.
• The TAPE IN jacks and REC OUT jacks let you easily connect a master recorder for recording or playback.

Obscure live mixer on dub matrix duty
This is not a well-known mixer and I had to do some digging just to get any info on it. I bought it used off ebay because I needed the 6 aux sends for dub mixes. It is essentially a 12x6 matrix mixer, plus 4 subgroup outs. Inserts and direct outs on every mono channel. Two stereo aux returns. The sound is "meh" -- typical late-80s/early-90's yammy sound reinforcement mixer. Nothing wrong with it, but not very detailed, to my ear heavy in the midrange. Input preamps don't have as much headroom as more recent mixers and are easy to drive into distortion -- especially because I'm mixing a lot of modular synth level (10 vpp) signals. Preamp distortion sounds good on drum machines, especially an 808 kick. Maybe comparable to 80's boss BX line mixers -- good for techno, but pretty low-fi. All in all, a hell of a bargain for the price I paid ($250), features-wise at least. When it got to me I opened it up and found a dead lizard skeleton inside that had presumably crawled in and gotten stuck, poor bastard. I had to reflow some solder joints to fix some intermittent connections, probably broken during shipping due to vibration and the age of the joints.
