By using the GAIN control (control panel 2)
you can connect any of the jacks to a wide range
of sources, from mics to line-level devices
(including synthesizers and rhythm machines).
The INPUT A jacks can provide +48V phantom
power, allowing you to use condenser micro-
phones.
The nominal input level is from –16 dB to –60 dB
when the 26 dB pad switch (control panel 1) is
off, or from +10 dB to –34 dB when it is on.
Both INPUT A and B are balanced.
They are compatible with microphones of output
impedance 50–600Ω or line level devices of
600Ω.
Pin connections for the jacks are as follows:
* You can also connect a normal unbalanced phone plug.
2INSERT I/O (insert) jacks
These are TRS phone jacks that enable you to
insert an external effect processor, such as a com-
pressor/limiter, between the equalizer and fader
of input channels. These connections require a
special “Y” cable, such as shown in the following
diagram. The nominal input/output levels are
0 dB.

Note: It is not possible to simultaneously use
both the INPUT A and B 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 simulta-
neously for channels 1–8 and 9–16 (EMX5000-
20), 1–8 (EMX5000-12). For this reason, devic-
es (in particular, unbalanced devices) other
than condenser microphones must be connect-
ed to the INPUT B input jacks of channels or
channel 17/18–19/20 (EMX5000-20), 9/10–11/
12 (EMX5000-12) input jacks if the PHAN-
TOM +48V switch (control panel 3) is on.
