ARCHITECT’S & ENGINEER’S

SPECIFICATION

The mixer shall be 12 in/2 out and shall incorporate 6 monophonic and 3 stereo line input channels, including 6 microphone channels. Microphone inputs shall be on XLR- type connectors, monophonic line inputs shall be on bal- anced 1/4Tip-Ring-Sleeve phone connectors, and stereo line inputs shall be on 1/4phone connectors. An inde- pendent stereo line-level CD/tape input (routed to chan- nels 11-12) shall be on phono connectors. Each channel shall have 2 Aux sends, 2-band equalization and a level control. In addition, monophonic channels shall have a stereo panpot and stereo channels shall have a left/right balance control. Microphone inputs (on channels 1-6) shall have an input trim control.

The mixer shall provide main outputs on balanced 1/4Tip-Ring-Sleeve phone connectors, effects outputs on 1/4phone connectors, and a headphone output on a 1/4Tip-Ring-Sleeve phone connector. 2 stereo effects returns shall be provided on 1/4phone connectors, and each shall have an independent level control. The mixer shall be powered either from provided mains adapter or from optional battery pack. The unit shall be of an ultra- compact type.

The mixer shall have residual noise of 95 dB, THD less than 0.01%, and frequency response of ±3 dB from 10 Hz to 50 kHz. Dimensions shall be 12.8(324 mm) wide,

9(228 mm) deep and 2.3(58 mm) high. Weight shall be

6.5lb. (2.9 kg). The mixer shall carry a three-year warran-

ty.

The mixer shall be a SAMSON MIXPAD 12.
