960L Owner’s Maunal The Mainframe

Installation

Mounting

The 960L mounts in stationary racks with four screws.

Make sure the 960L Mainframe is securely screwed into

the rack. For moving and in roadcases, be sure that

support is provided for the rear of the chassis to avoid

possible damage.

Ventilation

Provide adequate ventilation if the 960L is mounted in a

closed rack with heat-producing equipment such as

synthesizer modules, effects units, or power amplifiers.

Avoid mounting the 960L Mainframe directly above

power amplifiers.

Location

It may be desirable to place the 960L Mainframe in a

location remote from the listening environment. The

mainframe can be located up to 1,000 feet from the

LARC2 controller with a remote power pack. See

Chapter 2 for more information.

IEC Power Connector

The 960L is equipped with a 3-pin IEC power connector

and detachable cord, providing chassis grounding to

the AC mains line. Plug the female end of the power

cord into the 960L mainframe and the male end into a

wall outlet.

Mains Voltage Selector

Before connecting the 960L Mainframe to power

mains, make sure the setting matches your local

mains voltage.

Use a flat screwdriver to move the switch to the desired

voltage.

Analog Audio Connections

For best results, the 960L should be connected to your

console’s Aux sends/returns, with wet/dry mixing and

most input settings performed at the console. However,

controls are provided within the 960L for situations

where this is not possible or convenient.

For optimal performance, maintain balanced

connections, and use high-quality, low-capacitance,

shielded, twisted-pair cables, such as Belden 8412

(microphone cable with braided shield) or Belden 9461

(foil shield).

All connections should be Pin 2 high. For unbalanced

operation, Pins 1 and 3 should be grounded. For mono

inputs in a stereo configuration, connect the left and

right input channels in parallel. Be careful to keep inputs

and outputs of all channels wired consistently. Out-of-

phase wiring can produce audible effects.

For I/O panning and level control, see Chapter 4,

Operations in Detail. All signals sent to the analog

outputs are also sent to the digital outputs.

Important:

Analog I/O connectors must be wired consistently

(we recommend Pin 2 high), or channels will be out

of phase.
