BACK PANEL OPERATION
© INPUT
Both the LO-Z (low impedance) and HI-Z (high imped-
ance) INPUT jacks are unbalanced.
Connect low-impedance and high-impedance micro-
phones, general electrical and electronic musical instru-
ments and LINE inputs to the HI-Z INPUT jacks.
Connect low-impedance microphones to the LO-Z
INPUT jacks.
It is not possible to use both the LO-Z and HI-Z
INPUT jacks simultaneously for the same channel.
Ө SPEAKERS
Connect the main speakers to these Jacks.

When two S4115H speakers are connected to two jacks
of the same channel as in the figure, this parallel connec-
tion reduces the overall impedance to 4 ohms.
@ AUX IN
Connect the tape deck (playback) or another mixer for
increasing the number of channels to these jacks.
@ LINE OUT
Use these jacks to feed out the recording output signals
or the signals produced when the mixer is being used as a
submixer in order to increase the number of channels.
@ MON. OUT 1, MON. OUT 2
Use these jacks to connect the holdback (stage monitor)
speaker.
* A power amplifier is required for both MON OUT 1
and MON OUT 2 jacks. Use a speaker with a built-in
power amplifier or use a separate power amplifier.
Q ECHO RETURN, ECHO SEND
These are the input and output jacks for the echo unit.
(When the echo unit is connected, it is no longer possible
to use the built-in reverberation unit.) Use the MONI-
TOR 1 (REV/ECHO) controls to control the echo effect
for each of the individual channels, and the MONITOR 1
master fader and REVERB/ECHO control to control the
overall effect.
ө РОМЕН АМР ІМ
These external input jacks may be used in various ways,
such as when using the built-in power amplifier indepen-
dently (feeding input signals of another mixer), or when
amplifying PGM signals and monitor signals with a
separate power amplifier and the built-in power amplifier
respectively so as to increase power of PGM signals.
When amplifying monitor signals by the
built-in power amplifier.
