The DATEQ TRI-O is a six channel 19-inch 3-zone mixer. It is highly suitable for use in pubs, dancing- schools, conference centres etc. The TRI-O is equipped with three microphone inputs and 8 stereo-line inputs. The inputs can be routed to the 3 master outputs.
   
Channel 1 has a talk-over circuit to improve the speech intelligibility. This circuit, which is triggered by the microphone signal from channel 1 (i.e. it is voice-activated), ensures that this signal overrides all others. The talk-over function can be disabled with the TalkOver switch on the front.
By default three output zones are available (master A, B and C). These zones have a dual equaliser, balance and gain-control. In addition a maximum of four output modules (output zones) may be added. The volume of these additional zones is externally adjustable with a potentiometer CREWXOUT-W / CREWXOUT-B (not included) or an external regulation voltage.
The master outputs are electronically balanced on XLR and unbalanced on cinch connectors. The balanced output makes it possible to use long signal-cables so that the amplifiers can be placed near to the speakers. The optional output zones are equipped with unbalanced cinch connectors.
Channel 2 has a connection for a Musicall local line input, MRA-2WW or MRA-2GG. (not included)
