SRM-80A / E – SIGNAL ROUTER/MONITOR
INTRODUCTION
Congratulations on your purchase
of a Furman Model SRM-80A Signal
Router/Monitor. Your SRM-80A will
make monitoring, mixdown, and dub-
bing sim pler and faster, thus help ing
you achieve professional results.
ABOUT THE SRM-80
The SRM-80A facilitates mixdown and dub-
bing between different media types without
tying up additional console chan nels. By con-
necting the control room outputs of your mixer,
inputs and of up to three power am pli fi ers or
powered speak ers, speaker outputs of one
stereo power amplifi er, and up to three pairs
of speakers, you will have a highly useful and
sophisticated audio playback monitor system.
Multiple copies can be made si mul ta neous ly

SRM-80A / E – SIGNAL ROUTER/MONITOR
STEP-BY-STEP GUIDE TO SET-UP USING SINGLE POWER AMP
●
Please also refer to the “System Set-Up #1” drawing on the facing page.
●
Cables needed:
2 Pair: Speaker to Binding Posts, the banana plug type (Speakers B, C)
1 Pair: 1/4” TRS Balanced to Monitor Line output “A” (Powered Speakers)
6 Pair: RCA I/O to Devices
2 Pair: 1/4” TRS Balanced to Device “A” L/R I/O
1 Pair: 1/4” TRS Balanced to “SOURCE” L/R Input
1 Pair: 1/4” TRS Balanced to Power Amp L/R Inputs
1 Pair: Power Amp Out to “FROM POWER AMP OUT” Binding Posts (banana plugs)
●
Make sure SRM-80 and all other devices are switched “OFF” before making any cable connections.
●
Decide which devices will be labeled “A”, “B”, “C”, and “D”. Device “A” should be any pro level balanced units,
such as a DAT machine. Label the Output Select Switch and the speaker pairs on the front panel tabs. Use
adhesive labels so you can relabel for different confi gurations.
●
Mount the SRM-80 in your rack. Depending on your setup, it may be easier to cable all your gear before mount-
ing the SRM-80 in your rack. Otherwise, go ahead and mount it now.
●
Set AMP/SPK - B/C Switch to SPK - B/C.
●
Connect passive speaker cables to “SPEAKER C” and “SPEAKER B” Binding Posts.
●
Connect Power Amp L/R Output cables to “FROM AMP OUTPUT” Binding Posts.
●
If you have the optional SRM-RU remote unit, which we highly recommend, connect its 5-Pin
cable to “RE MOTE.”
●
Connect 1/4” TRS Balanced cables from your powered monitors to MONITOR LINE OUTPUT “A” L/R.
●
Connect 1/4” TRS Balanced cables from MONITOR LINE OUT PUT “B” L/R to your power amp “IN” L/R.
●
Connect RCA cables from “L/R In/Out” to devices “B”, “C”, and “D”, according to your setup plan.
●
Connect 1/4” TRS Balanced cables from “A” L/R, I/O to device “A”
●
Connect 1/4” TRS Balanced cables from “SOURCE” L/R to source device.
(e.g. mixing console stereo out or soundcard out).
●
Set the Ground Lift Switch to the position that reduces any hum or buzz.
●
Set the “0db / +4db” switch to the appropriate meter scale for the equipment being used.
●
Power up your equipment, being sure to turn on your power amp last.
●
Set “SPEAKER TRIM” controls at about 75%. After powering up the system, adjust levels as needed. To dial in
your speaker levels use broadband pink noise and sound level meter. The Alan Parsons/Stephen Court align-
ment CD is very good, and a decent meter can be had for about $40 at Radio Shack.
For using more than 1 pair of power speakers or multiple power amps see System Set-up #2 on the next page.

source select knobs labeled OUT PUT SE-
LECT A through OUTPUT SELECT D.
Monitoring any of these sources can be done
using the MONITOR SELECT knob, high-
power headphone amp and uniquely thought-
out speaker selection system that consists of
three balanced line level speak er outputs A,
B, and C. All of these outputs are compatible
with powered monitors or passive speakers
using a power amp. The unique feature is that
the B and C outputs can be combined into one
output for use with 2 pairs of passive speakers
and only one power amp. See de scrip tion of
B/C AMP/SPK Switch. Each mon i tor speaker
output has its own front panel trim control, so
equal listening levels can be main tained de-
spite dif fer enc es in speaker ef fi cien cies.
The SRM-80A has balanced inputs for the
SOURCE and A inputs, and balanced outputs
for channel A output and A, B, and C moni-
tor line outputs. INPUTS B through D utilize
un bal anced RCA jacks. The SRM-80A allows
easy signal routing between these dissimilar
jacks.

SRM-80A / E – SIGNAL ROUTER/MONITOR
The SRM-80A provides a high-resolution 40
LED x 2 bar graph meter to display the signal
selected for listening. The meter displays a
pre-fader signal for accurate monitoring of
the signal going to tape or disc. This meter
has true VU ballistics, or can be switched to
Peak Program Mode via the front panel toggle
switch. The meter also features a slow re-
lease-time Peak Hold function to allow easy
ver i fi ca tion of critical levels.
The SRM-80A’s MONO SUM feature provides
the ability to check for radio compatibility,
and is a good spot check to see how you’ve
messed up the stereo image! (Only the sends
to the speakers are af fect ed.) While radio air-
play is nearly always stereo these days, phas-
ing problems and odd panning ar range ments
can show up in less than ideal listening envi-
ronments, such as cars, and many lo ca tions in
nightclubs.
The SRM-80A also features a DIM switch to
allow an easy way to lower the level to the
speakers (but not the headphones) tem po -
rari ly without disturbing any level controls.

ABOUT THIS MANUAL
We want to make it easy for you to set up your
SRM-80A. Page Two of this manual tells you
how to do just that, step-by-step. Page four
gives you detailed information on all of the
features, controls and connectors. You can
set up your SRM-80A fi rst, and read about the
controls afterwards or even better, just resume
re cord ing and mixing!
INSTALLATION
The SRM-80A is intended for mounting in
standard 19" equipment racks. To avoid mar-
ring the panel when tightening the screws, use
nylon washers under the screw heads.
SAFETY INFORMATION
WARNING (For domestic units only): Do not
remove the third prong on the SRM-80A’s AC
plug. Never use a 3-prong to 2-prong AC plug
adapter to plug your SRM-80A into your wall
socket. The unit requires that a safety ground
be present for proper operation. Any attempt to
operate it without a safety ground is considered
im prop er op er a tion and could invalidate the
warranty.
FRONT PANEL CONTROLS

SRM-80A / E – SIGNAL ROUTER/MONITOR
DAT can receive signals from de vice “Source”,
“B”, “C”, or “D” INPUTS de pend ing on where
you position this knob.
OUTPUT SELECT B: This four-position knob
works like the output select “A” knob de scribed
above. For example, if the “B” RCA OUTPUTS
on the back panel are used for a cassette
recorder, the recorder can receive signals from
stereo device Source, “A”, “C”, or “D” INPUTS.
OUTPUT SELECT C: The SRM-80A’s “C”
OUTPUTS can receive signals from device
“Source”, “A”, “B”, or “D” INPUTS depending
on where you position this knob. For example,
if the “C” RCA OUTPUTS on the back panel
are used for a MiniDisc recorder, the re-
corder can receive signals from stereo device
“Source”, “A”, “B”, or “D” INPUTS.
OUTPUT SELECT D: The SRM-80A’s “D”
OUTPUTS can receive signals from device
“Source” “A”, “B”, or “C” INPUTS. For ex-
am ple, if the “D” RCA OUTPUTS on the back
panel are used for a CD player/recorder, the
re cord er can receive signals from stereo de-
vice “Source”, “A”, “B”, or “C” INPUTS.
MONITOR SELECT: This fi ve-position knob
allows you to select which device you will hear
through your speakers and headphones, the
main console or soundcard mix (Source), or
the output of any devices “A” through “D”.
LISTENING LEVEL: Controls the loudness
level you hear through your speakers. It does
not affect the signal going to any of the stereo
devices connected to the SRM-80A.
MONO: Changes the sound you hear through
your speakers (not in the Headphones) from
stereo to monaural.
DIM: Attenuates the loudness of your speak ers
by about 15 dB, without affecting the level of
the signals going to any of the stereo de vic es or
headphones connected to the SRM-80A. This
is a very useful feature if you are in ter rupt ed
while monitoring, mixing, or dub bing.
MONITOR LEVEL: This high-resolution, 40 x 2
LED bar graph meter allows precise pre-fade
level calibration for all stereo devices con-
nect ed to the SRM-80A.
METER MODE: Located to the right of Mon-
i tor Level Meter, this switch can be set for the
meter to display AVG (VU) or Peak Mode.
SPEAKERS A, B, and C: Selects between
amplifi er / speaker outputs A, B, or C.
TRIM LEVELS: Adjusting these “Set Once”
controls allows you to set all three pairs of am-
plifi ers/speakers to the same listening level.
HEADPHONES: Plug your headphones in
here. The high-power headphone amp pro-
vides excellent audio quality and can drive
low-impedance phones with ease. It may be
wise to disconnect your headphones to avoid
damage when not in use.
HEADPHONE LEVEL: Adjusts the listening
level of the headphones.
REAR PANEL CONTROLS AND
CONNECTIONS
GROUND LIFT: Allows separation of chassis
ground from audio ground and can be used
to reduce hum or buzz. Remember, never
re move the third prong on the SRM-80A’s AC
6

SRM-80A / E – SIGNAL ROUTER/MONITOR
plug. Never use a three-prong to two-prong
AC plug adapter to plug your SRM-80A into
your wall socket.
ON/OFF: Controls power to unit.
AMP-B/C & SPK-B/C SWITCH: When the B/C
switch is in the AMP-B/C position: The input
selected by the Monitor Select switch is routed
through the Monitor level control and sent to
the “A”, “B” or “C” mon i tor line outputs (as
selected with the “A”, “B” or “C” pushbuttons).
B and C speaker outputs and output signals
are separate for use as in di vid u al outputs with
either powered speak ers or passive speakers
with a power amp. See Figure A.
When the AMP/SPK B/C switch is in the SPK-
B/C position: Only the “A” and “B” monitor
line outputs are used and the “B” amplifi er’s
speak er outputs are connected to the “FROM
AMP (B) OUTPUT” binding posts. The B
and C speaker outputs are combined to the
SPEAK ER B output jacks. This is to be used
with a single power amp and 2 pairs of pas-
sive speakers via the binding posts on rear
panel. Connect the SPEAKER B/POWER
AMP IN jacks to the input of your power amp.
Con nect the output of your power amp to the
FROM AMP OUTPUT Binding posts. Connect
1 pair of passive speakers to the SPEAKER
B binding posts and the other pair of passive
speakers to the SPEAKER C binding posts. To
select the associated amplifi er / speaker press
the “A”, “B,” or “C” speaker select but tons on
the front panel. See Figure B.
