MIXPAD 9
ULTRA-COMPACT
MIXER
The ultra-compact MIXPAD 9 Mixer is a 9 input
stereo mic/line mixer in a very small package. Equipped
with 2-band equalization and pan/balance and level con-
trols on each channel, the MIXPAD 9 is an ideal device
for ENG, field recording, broadcasting and contracting
applications. It also features optional battery power, a
front-panel stereo headphone jack, 3 electronically bal-
anced mic/line inputs (XLR and 1/4″connectors), 3
stereo line inputs (1/4″connectors), a CD/tape input
(phono connectors), 48 volt phantom power, 2 Aux
sends and 2 stereo Aux returns (which have indepen-
dent level controls and so can be used as 4 mono Aux
returns), as well as a main level control and power and
peak LEDs.

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
