ARCHITECT’S & ENGINEER’S SPECIFICATION

The mixer shall be 9 in/2 out and shall incorporate 3

monophonic and 3 stereo line input channels, including 3

microphone channels. Microphone inputs shall be on XLR-

type connectors, monophonic line inputs shall be on bal-

anced 1/4′′ Tip-Ring-Sleeve phone connectors, and stereo

line inputs shall be on 1/4′′ phone connectors. An indepen-

dent stereo line-level CD/tape input (routed to channels 8-

9) shall be on phono connectors. Each channel shall have 2

Aux sends, 2-band equalization and a level control. In addi-

tion, 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

1/4′′ Tip-Ring-Sleeve phone connectors, effects outputs on

1/4′′ phone connectors, and a headphone output on a 1/4′′

Tip-Ring-Sleeve phone connector. 2 stereo effects returns

shall be provided on 1/4′′ phone 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 9.4(239 mm) wide, 9

(228 mm) deep and 2.3(58 mm) high. Weight shall be 5.5

lb. (2.5 kg). The mixer shall carry a three-year warranty.

The mixer shall be a SAMSON MIXPAD 9.
