⭕ The unit is in very good order for its age with only minor/average surface wear. The external unit uses a D-Sub connector to connect and will plug straight into your DAW interface for easy recording. The desk has 10 channels, each with two auxs, pan and AFL. It has 10 x 3116 modules. These modules sound fabulous as you would expect and have 47/82Hz bass cut, HF and LF EQ and trim. The master section has controls for aux masters, solo, and talkback volume, oscillator tone and solo/group etc. The VU meters are switchable between outputs, inputs and auxs. The rear of the unit has XLR connectors:- 10 channel inputs, 2 monitor outputs, 2 Aux outputs, 2 playback inputs, 2 talkback, solo, 2 mix outputs. By the power supply port is the D-Sub connector for the external unit. Ive had this desk for a fairly short time, Ive not had it serviced while Ive owned it, but the previous owner did shortly before I bought it. Its only had careful, loving, smoke free studio use
