The unit was carefully packed at the factory to protect against damage in
transit. Nevertheless, be sure to inspect the unit and shipping carton for any
signs of damage that may have occurred during shipment. If there is any
damage, notify us immediately for further instructions. It's also a good idea to
save the carton and packing materials should you ever need to return the unit
for repair. The shipping carton should contain the following items: the PL-2
Analog Peak Limiter, an IEC 3 prong power cord, and this operating manual.
Mounting
The PL-2 uses one EIA-standard rack space, and can be mounted in any
standard 19 inch (483mm) equipment rack. If the PL-2 is mounted in a mobile
rack or road case, it is important that the rear of the chassis is supported to
prevent possible damage from mechanical shock and vibration. Please avoid
rough handling.
Ventilation
For proper operation, it is important that adequate ventilation is provided. Heat
generated inside the unit is radiated out through the ventilation holes in the
side panels. Do not block these vents. Never operate the PL-2 inside a road
case where the side panels are blocked.
Power Requirements
The PL-2 is equipped with a 3-prong IEC power connector and detachable
cord. Never operate the PL-2 with the ground on the power cord defeated.
Unless otherwise stated, this unit operates from either 115-120V/60 Hz or
230-240V/50 Hz at 16W. Before the unit is plugged in, select the correct ac
voltage using the switch adjacent to the IEC inlet on the rear panel. The ac
fuse is accessible within the rear panel IEC input jack and is rated at
1.5A/250V (5x20mm) SLO-BLO. To check or replace the fuse, unplug the
power cable from the IEC input jack.
Servicing
The user should not attempt to service the PL-2 beyond replacing the fuse. To
reduce the risk of fire or electrical shock, do not expose to rain or moisture, or
operate it where it is exposed to water. Since potentially lethal voltages are
present inside the unit, it should only be opened by qualified service
personnel. Refer all servicing, or any questions about servicing, to Pendulum
Audio, Inc.
Hookup
Please refer to the rear panel layout (see the Condensed Operating Instructions)
for the location of the inputs, outputs, ac power inlet and power switch. Make
all connections to the PL-2 and select the proper ac voltage before applying
power.
Inputs and Outputs
On the right hand side of the rear panel are the XLR input and output jacks for
channels 1 and 2. Connect line-level sources to the PL-2 using standard
balanced XLR cables. Pin 1 = ground. Pin 2 = + (positive phase), pin 3 = -
(negative phase). Note: Do not connect the outputs of the PL-2 to an input that
has +48V phantom power applied to it.
