INPUT Jack (monaural)
These monaural input jacks are used to connect micro-
phones or musical instruments. Each input channel fea-
tures two types of jacks (INPUT A and INPUT B).
• INPUT A Jack
These are balanced XLR-3-31 type input jacks (1:
Ground; 2: Hot; 3: Cold).
• INPUT B Jack
These are TRS phone-jack type balanced inputs. (T:
Hot; R; Cold; S: Ground)
You can connect either balanced or unbalanced phone
plugs to these jacks.
NOTE
· Only one type of jack can be used at a time on a single
channel.
2
INSERT Jack
These jacks are located between the compressor and
equalizer of the corresponding monaural input channel.
The INSERT jacks are ideal for connecting devices such
as graphic equalizers or noise filters into the corre-
sponding channels. The INSERT jacks are TRS (tip,
ring, sleeve) phone jacks that carry both the send and
return signal (tip = send/out; ring = return/in; sleeve =
ground).

DIRECT OUT Jack
These are impedance balanced (page 19) phone-jack
type outputs. They output the signal that has passed
through the compressor.
NOTE
· If necessary, the signal that is output from the DIRECT
OUT jack can be changed to the signal immediately
before the channel fader (pre-fader) or the signal after
the channel fader (post-fader) by changing an internal
jumper. A fee will be charged for this modification. For
details, contact to your Yamaha dealer listed at the end of
this manual.

INPUT Jacks (stereo)

instruments, such as a synthesizer. Each input channel
features two types of jacks (INPUT A and INPUT B).
• INPUT A Jacks
These are unbalanced phone-jack stereo line inputs.
• INPUT B Jacks
These are unbalanced stereo RCA pin-jack line inputs.
NOTE
· Only one type of jack can be used at a time on a single
channel.
