4 MN610 10 CHANNEL BOOTH MONITOR
INTRODUCTION
The MN610 is a 10 channel booth monitor that monitors both
sound processor and amplifier outputs while incorporating a
number of advanced features:
•10 Channels. The MN610’s 20 inputs are split between
processor and amplifier banks of 10 each. The banks are
selectable using the MODE button located on the front
panel.
•Balanced Inputs. To avoid ground loop hum, the MN610
has balanced inputs on all channels.
•THX Standard DB25 Processor Input. Connecting a
processor with a THX Standard output is quick and easy.
•Biamp/Triamp Monitoring. Both the processor and
amplifier banks provide Biamp and Triamp monitoring for
the Left, Center and Right channels.
•Multiple Channel Monitoring. The multiple pushbutton
interface allows the user to add in all ten channels on either
bank to the output amplifier.
•Multiple Outputs. There are three different ways to
monitor from the built-in 10 Watt Power Amplifier:
1. Built in 3 1/2" speaker.
2. 1/4" phono rear panel external speaker jack.
3. 1/4" front panel headphone jack.

USER’S GUIDE 5
INSTALLATION
1. Mount the MN610 in a convenient 3
1/2" rack space using four rack
bolts. Ideally, the monitor should be
located between the processor and the
amplifiers.
2. Using shielded pair wire, connect
the outputs of the processor to the
appropriate inputs on the monitor.
For balanced outputs, tie the positive
(+) terminal of the processor to the
positive (+) terminal on the monitor,
and tie the negative (-) terminal of the
processor to the negative (-) terminal on the monitor. For
unbalanced outputs, use the ground terminal (GND, E) on
the processor to tie to the negative (-) terminal on the
monitor. Tie the shield of the cable to the ground (GND, E)
at the processor, leaving the shield unconnected at the
monitor. Alternatively, if
the processor
has a THX
Standard output
for monitoring,
connect the
DB25 cable to
the appropriate
jacks on the
processor and
monitor. Do NOT apply signal to both the terminal block
and DB25 connector inputs for the same signal. LEFT
REAR, RIGHT REAR, and any MID or HI frequency terminal
block inputs may be safely used in conjunction with the
DB25 connector.

3. Using unshielded pair
wire, connect the
outputs of the
amplifier to the
appropriate inputs on
the monitor. As with a
balanced processor, tie
the positive (+) terminal
of the amplifier to the
positive (+) terminal of
the monitor. Tie the
negative (-) terminal of
the amplifier to the
negative (-) terminal of
the monitor.
Single Frequency
Band Monitoring. For
single frequency Left,
Center and Right
channels, use the corresponding “Lo” inputs.
Split Frequency Band (Biamp, Triamp) Monitoring.
For Biamped Left, Center and Right channels, use the “Lo”
inputs for the low frequency band, and the “Hi” Inputs for the
higher frequency band. For Triamped Left, Center, and
Right channels, use the “Lo” for low, “Mid” for middle and
“Hi” for high frequency bands.
4. Set the processor and amplifier gain trimpots for the
desired level. After the processor and amplifiers have
been set up and calibrated for optimal presentation,
run pink noise through the processor set at the cal
point volume level. Select processor mode and a
channel with pink noise on the monitor. Using a
tuning wand or equivalent, adjust the P Gain Trimpot
(located on the front of the monitor unit) until the third

Signal Presence LED just comes on. Change to amplifier
mode on the monitor, and repeat using the A Gain Trimpot.
The monitor volume knob may be turned down during this
adjustment. If the monitor sound level is not high enough,
these pots may be adjusted clockwise for additional gain.
5. Add an external speaker ( optional ). The MN610
provides a 1/4"/6.3mm
external speaker jack on
the rear of the unit. Wire a
4 or 8 ohm speaker to a
mono 1/4" phono jack and
insert in the jack labeled
EXTERNAL SPEAKER.
When the external speaker
jack is used, the built-in
speaker is disconnected.

OPERATION
Power is applied to the unit when the red
POWER LED on the front panel is lit. The 1/
4” mono HEADPHONE jack allows for better
listening in a noisy booth environment. It is
wired in parallel with the internal/external
speaker outputs. The main VOLUME knob
controls the volume for all outputs.
The SIGNAL LEVEL LEDs indicate the
relative amplitude of monitored signals.
The levels displayed are not calibrated
to any standard audio measurement.
The level indicated is also not affected
by the output level set by the VOLUME
knob.
The MODE switch selects either the processor or amplifier
bank of inputs for monitoring.
Pushing a switch to the “in”
position adds the corresponding
channel to the monitoring mix.
Note: Since monitoring more
than one channel “adds”the
channels together before the
final amplification, monitoring
many channels at once may cause overload distortion.
While this is not dangerous to the monitor, it will not
accurately represent the sound quality of the system.
