Input and Output Connections

The S4000 mixer has 20 mono mic/line and stereo line input channels, for connecting a variety
of signal sources from microphones to line level devices such as synthesizers, drum machines and
direct boxes.

Channel 1-12 Mono Mic/Line Inputs

The mono mic/line inputs each have a LINE level input, a MIC level input and an Insert connector
for effects.
A. MIC (Microphone) Input - Use these inputs to connect Low Impedance micro-
phones and low-level signals from direct boxes. The MIC inputs have a nom-
inal operating level of –50dBV through -20dBV. The MIC inputs also feature
+48V phantom power, allowing you to use condenser microphones. The
Phantom Power is switched on/off simultaneously for channels 1 through 12.
B. LINE (Line Level) Input - Use these inputs to connect high impedance micro-
phones, synthesizers and drum machines. The LINE inputs have a nominal
operating level of -40dBV through - 10dBV.
NOTE: It is not possible to simultaneously use both the LINE and MIC inputs
on the same channel. For each channel, use only one of the inputs as appropriate for the
input source.
C. INSERT (Send and Return) jack - The S4000 have a ¼", TRS (TIP/RING/SLEEVE) Insert jack
for connecting outboard effects processors directly on the channel input. The signal is sent
on the tip (the Send) and returns on the ring (the Return) of the connector.

Channel 13-20 Stereo Input Channels

The stereo input channels are used for connecting stereo signals like those from CD or MP3
players, electronic keyboards, drum machines and other line level signals.
D. Stereo Inputs (RCA jacks) - The stereo channel's RCA
connectors accept signals from stereo line devices. The
RCA line level inputs have a nominal operating level of
-40dBV through - 10dBV.
E. Stereo Inputs (¼" jacks) - Use the ¼" jacks for connect-
ing stereo line level sources. For stereo inputs use the
LINE L to connect the left channel and the LINE R to
connect the right channel. Use these inputs to connect
high impedance microphones, synthesizers and drum
machines. The LINE inputs have a nominal operating
level of -40dBV through - 10dBV.

CD/TAPE IN and RECORD OUT

You can interface a digital recorder, computer sound card or other recorders using the S4000's
CD/TAPE and RECORD OUT.
F. CD/TAPE Inputs (RCA jacks) - Stereo line level input, on RCA connectors, for connecting the
output of devices such as MP3, CD, computer sound-card, or any other line level device.
G. Record Out (RCA jacks) - The signal present at this connector is the MAIN bus signal before
it has passed through the MASTER level control and graphic equalizer. The nominal output
level is -10dBV and the impedance is 100 Ohms.
