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.
