1Channel input jacks (Hi-Z, Low-Z)
1–6 (EMX88S), 1–4 (EMX68S)
These are the input jacks for channels
1–6 (EMX88S), 1–4 (EMX68S).
By using the PAD switches (control panel 6) you
can connect any of the jacks to a wide range of
sources from mics to line level devices (synthesiz-
ers or rhythm boxes etc.). The Low-Z jacks can
provide +15 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Low-Z are balanced, and are com-
patible with microphones of output impedance
50–600Ω or line level devices of 600Ω. The nom-
inal input level is from –40 dB to –10 dB for the
Hi-Z jacks, and from –50 dB to –20 dB for the
Low-Z jacks.
Pin connections for the Hi-Z and Low-Z jacks are
as follows.
2Super Hi-Z jacks
These two phone jacks are the input connectors
for input channel 5–6 (EMX88S), 3–4 (EMX68S).
They are unbalanced, can be used simulta-
neously, and their high input impedance makes
them ideal for use with instruments such as elec-
tric-acoustic guitar and electric bass. They can
also be used with line-level sources, such as syn-
thesizers and drum machines.
3Channel input jacks (MIC/LINE)
7–8 (EMX88S), 5–5 (EMX68S)
These are the input jacks for channels
7–8 (EMX88S), 5–6 (EMX68S).
Connect microphones to the MIC jacks. Connect
line-level devices, such as synthesizers to LINE L
(MONO)/R jacks if the devices are stereo sound
sources. Use the LINE L (MONO) jack if the
devices are monaural sound sources. The MIC
jacks can provide +15 V phantom power, allow-
ing you to use condenser microphones.
The MIC jacks are balanced, and are compatible
with microphones of output impedance 50–
600Ω.
The LINE jacks are unbalanced, and are compati-
ble with line level devices of 600Ω output imped-
ance. Nominal input level is –50 dB for the MIC
jacks and –10 dB for the LINE jacks.

Note: It is not possible to simultaneously use
both the Hi-Z and Low-Z inputs of a given
channel. For each channel, use only one of the
inputs as appropriate for the input source.
Phantom power is switched on/off in simulta-
neously for channels 1–8 (EMX88S), 1–6
(EMX68S). For this reason, devices which do
not require phantom power must be connected
to the Hi-Z or LINE jacks if the PHANTOM
switch (control panel L) is on.

neously but their levels cannot be adjusted sep-
arately (Same for channel 8 (EMX88S),
6 (EMX68S).)
