Nady Systems PRM-400 owner manual Band Stereo Graphic Equalizer, Is post-Stereo Master faders

C O N T R O L S A N D C O N N E C T I O N S

The PRM-400 is equipped with a 7-
band Stereo Graphic Equalizer
(22), allowing final tonal adjustments
on the Master Mix. This master EQ
is post-Stereo Master faders	(19)
(27A,27B) so you must exercise
care in the proper use of these EQs
for best overall sound [see also
INPUT SECTION, (6) EQ above].
The EQ Bypass switch (25) can be
used to add or eliminate the Stereo	(19A)
EQ from the Master Mix (button
depressed=EQ bypassed).
Further processing of the Master
Mix can be done by utilizing the	(24)
stereo Master Inserts (14,15). The
PRE EQ insert (14) inserts a signal
from an outboard processor, as
desired, between the Stereo Master
faders (27A,27B) and the Stereo
Graphic Equalizer (22), while the	(23)
POST EQ insert(15) inserts it POST
EQ and before the PRM-400 internal	(25)
power amp. The insert points are
normalized, i.e., the signal is only
interrupted when a jack is plugged	(26)
into it. The insert jacks are config-
ured as: Tip = send, Ring = return,
Sleeve = ground.
The Inserts can also be used as
Master Mix pre or post-EQ direct
outputs by sending the signal from
the ring. To use an insert as a direct
output, insert a 1/4” phone plug
halfway into the insert jack so the tip
of the plug connects with the ring of
the insert jack. The jack will click
into place when the connection to
the ring is made. Such outputs can
thus serve as feeds for external
amplifiers or recording devices, for	(27A)
example.
The Aux/Mon Select switch (26)
can be used to switch between nor-
mal stereo L/R to dual mono opera-
tion, such as for powering separate	(27B)
mains and monitor speakers with

the PRM-400. The UP position is for stereo operation as described above, and the DOWN (depressed) position enables dual mono opera- tion as follows: The Left speaker output is a mono mix of both the Left and Right signals as controlled
