POWER

The IEC appliance input jack is connected to AC mains using a line cord appropriate for your area.

The high efficiency switching power supply used in the MP 44 operates at voltages from 85 VAC to

250 VAC, 50 or 60 Hz. To prevent accidental shutoff during the height of the show, there is no front

panel power switch. When applying power to the system, remember to turn power amplfiers on last.

WARNING: DO NOT OPERATE THIS UNIT WITHOUT THE LINE CORD EARTH

GROUND CONNECTED. TO DO SO MAY INCREASE THE RISK OF ELECTRIC SHOCK

and INCREASE LINE CORD CONDUCTED EMISSIONS.

OPTIONAL VR 1 REMOTE LEVEL CONTROL

The REMOTE LEVEL input jack is a 3-pin Euroblock connector. If no connection is made, the

gain is unaffected. The Vr pin provides a precision voltage reference. The Vc pin receives the VCA

(voltage controlled amplifier) control voltage. The third pin provides a ground reference for the port.

To use the VR 1 Remote Control, simply connect like labeled pins together.

To build your own remote control, use a linear taper potentiometer with a resistance of 1k Ω to

100k Ω. Connect ground to the CW terminal of the potentiometer. Connect Vc to the center wiper of

the potentiometer. Connect Vr to the CCW terminal of the potentiometer.

Another option is to use an external, ground referenced control voltage with a range of 0 to +5 volts.

The gain control law is 125 mV/dB (for each 125 mV applied to the Vc pin, the audio is attenuated by

1 dB).

The best option might be to use Rane's ready-to-go remote, the VR 1.

VR 1 REMOTE MOUNTING

The VR 1 remote assembly mounts in a standard U.S. electrical box with a minimum depth of

2.25" (5.5 cm). Be sure to note the wire color of each input in order to facilitate correct wiring to the

MP 44. Connect each wire to the 3-pin connector by fully inserting it in the correct socket and tight-

ening the screw. Use the flat head #6 screws supplied with the kit to mount the remote assembly and

silk-screened front panel to the electrical box. Note the “UP” arrow screened on the printed circuit

board of each remote (mount it pointing up).

The silk-screened front panel metal is painted on both sides. This allows you to custom silk-screen

the panel or add your own custom decals. Simply install the modified front panel with your art facing

out, and you are in business!

Install the knob so that the line on the knob is properly aligned with the silk-screening on the

front panel of the remote. Install any Decora plate of your choice. For a secured installation, you may

wish to leave the knobs off and use a blank Decora plate to cover the remote after adjustment.

EUROBLOCK CONNECTIONS

When wiring to Euroblocks, a minimum wire gauge of 22 is preferred for reliability. If the ground

or shield wire is left shorter, it acts as a strain relief for the other wires. Cable with a flexible jacket is

easier to use and less likely to damage the connections. Make sure wires are free of nicks and that the

cable jacket is stripped back sufficiently to allow it to lie in the electrical box with the remote assembly

inserted, though avoid stripping excess insulation.

You may use 3-conductor unshielded remote control signal cable for shorter runs (less than 200

ft.) or 4-conductor (2 pair) shielded remote control signal cable (use the shield as the GND return) for

longer runs (200 to 1000 ft.). The type of wire required is influenced by your installation and local

electrical codes.

REMOTE INSTALLATION

Turn the power to the MP 44 off until all connections are made. It is important to ensure that the

Remote Ports are not subjected to sustained voltages outside the range of 0 to 5 volts DC or high levels

of static. Inputs are protected, however, caution is the better part of... you know. It is a good idea to

install the wiring, connect it to the Remote and then make the final connections at the MP 44. Do not

short the Vref pin to ground. This pin is current limited, however, excess heat is generated in the 5 volt

supply if a short occurs. Never subject the Vref pin to voltages above 5 volts.
