960L

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 pro-
vided 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 syn-
thesizer 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 loca-
tion 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 Section 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:
If your 960L has a mains voltage selector switch as
shown in Fig. 1-4, be sure the setting matches your
local voltage before connecting the Mainframe
to the mains.
Figure 1-4 (a) — Setting for
100-120 VAC
Use a flat screwdriver to move the switch to the desired
voltage.
If there is no selector switch (Fig. 1-5), it does not need set-
ting and will operate on mains voltages from 100-240 VAC.
Analog Audio Connections (if present)
For best results, the 960L should be connected to your con-
sole'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 connec-
tions, 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. 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 Section 4,
Operations in Detail.

IMPORTANT:
Analog I/O connectors must be wired consistently
(we recommend Pin 2 high), or channels will be
out of phase.
