Wharfedale PPS 1 System User Guide
Introduction
The Wharfedale PPS 1 Active system consists of a powered sub
bass unit with two satellite panels based on revolutionary
NXT™ Surface Sound technology. This unique technology
enables all listeners in the room to enjoy spacious, detailed
sound, not just the favoured few directly on line with the
speakers.

DO NOT connect the loudspeaker outputs of any unit to the
audio inputs of the 2.1.
The subwoofer has three amplifiers, one for the sub bass unit
and an amplifier for each NXT panel. The deep bass goes to the
subwoofer and the rest of the audio signal to the panels.
The PPS1 panels employ a protection mechanism that mutes
the sound if the power input is too great. If the output is muted,
turn down the main volume control on the system for a few
seconds to reset the level.

Mounting the Panels
The PPS 1 panels are designed to wall mount. Conventional

Initial Setting-up And Operation
Check that all system connections are correct. Set the Master
Level Control on the sub bass unit to minimum and the Power
switch to OFF. Connect the power lead to the mains.
Switch on the power to the subwoofer and check that the
Standby Indicator on the front panel glows. Connect the power
to the rest of the system. The system is now operational.
BASS LEVEL CONTROL
The Level control is located on the front panel. Use this control to
alter the amount of bass the subwoofer puts out. Do not set too
high a level or the sound will be bass heavy and the system may
distort at high volumes.
MASTER LEVEL CONTROL
This control alters the overall volume level of the loudspeaker
system. It may be used in two ways.
Where the Source Unit has a fixed output level: Use the
Master Level as the main volume control for the system. This is
typically be the case if you were using a Tuner. Some CD Players
and Cassette players have variable line outputs, most don't.
Where the Source Unit has a variable output level: This is
typically be the case if you are using the unit with a computer
sound card or via the Headphone socket on a portable audio
player. In this case you may either use the Master Level control
as the main system Volume control or as a preset.
Using the Master Level ae a Preset Control: Set the control
so that there is a wide range of operation at the source unit and
that the level is not "squashed up" at either extreme. (This will
normally correspond tothe 2 O'clock position). The main volume
control on the computer or portable unit will now be used as the
system control.
Auto Power On
The sub bass unit remains in Standby when there is no signal.
When it detects a signal it will switch on and the Operation light
glows. If there is no signal for about 30 seconds it will go to
Standby and the Standby light will again glow.
