REMOTE LEVEL CONTROL OPTIONAL

With the addition of the optional Remote

Level Control (HD-RLC), you can control the

volume of the subwoofer channel (Subwoofer

Level) or of the entire M700/5 from the front of

the vessel (Master Volume).

The HD-RLC connects to the jack labeled

“Remote Level Control” on the Connection Panel

of the amplifier using a standard telephone cable

(supplied with the HD-RLC). If desired, multiple

M (and HD) amplifiers can be controlled from a

single HD-RLC controller using a simple phone

line “splitter” and multiple phone cables.

When connected to the amplifier, the

HD-RLC operates as follows. At full counter-

clockwise rotation, the audio of the selected

channels will mute completely. At full clockwise

rotation the level will be the same as if the

HD-RLC was not connected at all. In other

words, it operates strictly as a level attenuator.

“Remote Level Mode” Switch: This switch

allows you to assign the operation of the

HD-RLC to the entire amplifier or only the

subwoofer channel. In the “Al l ” position, the

HD-RLC knob will affect all channels equally.

In the “Sub Ch.” position, only the level of

the subwoofer channel will be affected by the

HD-RLC knob.

SPEAKER OUTPUTS

The M700/5’s speaker outputs are designed

to accept 16 AWG - 8 AWG wire. To connect the

speaker wires to the amplifier, first back out the

set screws on the top of the terminal block, using

the supplied 2.5 mm hex wrench. Strip 1/2 inch

(12 mm) of insulation from the end of each wire

and insert the bare wire into the terminal block,

seating it firmly so that no bare wire is exposed.

While holding the wire in place, tighten the set

screw firmly, taking care not to strip the head of

the screw.

Each pair of the M700/5’s main channels are

designed to deliver power into speaker loads equal

to or greater than 2 ohms when using a “stereo”

configuration and speaker loads equal to or greater

than 4 ohms when using a “bridged” configuration.

The subwoofer channel is designed to deliver power

into subwoofer loads equal to or greater than 2 ohms.

Speaker loads below 2 ohms nominal per

channel (or 4 ohms bridged) are not

recommended and may cause the amplifier

to initiate a protection mode which reduces

power output.

BRIDGING CONSIDERATIONS

Bridging is the practice of combining the

output of two amplifier channels to drive a single

load. When bridged, each channel produces

signals of equal magnitude, but opposite polarity.

The combined output of the two channels

provides twice the output voltage available from

a single channel. The M700/5 has been designed

for bridging of its main channel pairs without the

need for input inversion adaptors.

To bridge a pair of main channels, use the

“Left +” and “Right –” speaker connectors only

(the “Left –” and “Right +” remain unused). Each

bridged channel pair will deliver optimum power

into a 4 ohm load.
