Wharfedale 8000S - Manual (Page 4)

3: Input & Output Connections
Pre-Power Mode
Pre Mode
Pre-Power AV
The pre-amplifier section is internally connected to the power
amplifier. The pre-amplifier outputs are operational.
A powered subwoofer can be connected to the pre-amplifier
outputs
A second power amplifier can be connected for bi-amplifying as
shown in the diagram.
An additional power amplifier can also be connected to drive a
second pair of speakers in a remote location.
All signals to and from the power amplifier of the 8000S are
disconnected. In this mode, the 8000S functions as a stand-alone
pre-amplifier.
The pre-amplifier section of the 8000S can be connected to a
stereo power amplifier, or to two monobloc amplifiers .
The pre-amplifier and power amplifier sections operate
independently. This mode can be used to connect a multichannel
AV processor.
The processor should be connected via any spare tape output or, as
an alternative, one of the pre-amp outputs.

The six inputs may be used for connecting any line level source.
Three sets of record outputs for connection of up to three stereo
audio recorders, e.g. tape recorder, CD recorder, audio recording
input of VCR ,DVD, MP3, MiniDisc recorder, etc.
Low impedance (100 ohm) pre-amplifier outputs for driving
external power amplifiers, sub-woofers or signal processors. Long
cables may be used if required. Pre-amp outputs are switched off
when integrated mode is selected or whenever amplifier is muted.
For driving the power amplifier input directly from an external
source. Only operates when pre power AV mode is selected.
Two sets of loudspeaker output terminals connected in parallel.
Use only if phono pre-amplifier and turntable are used and both
are Class II double insulated (no earth connection). In this case the
ground terminal can be connected to the metalwork of these units
to eliminate residual hum. The ground terminal must not be used
as a safety earth. If in doubt consult your dealer.
Connecting Loudspeakers
Switch power off when connecting loudspeakers.
Use good quality low resistance loudspeaker cable.
Connect the Positive RED (+) terminal of the
amplifier to the Positive (+) RED terminal of the
loudspeaker. Connect the Negative (-) BLACK
terminals similarly.
When connecting loudspeakers tighten the
terminals securely by hand.
Make there are no loose strands of wire which could
cause shorts.
Standard Loudspeaker Connection
You can connect a speaker switching box or headphone adaptor to the unused set of speaker terminals
Loudspeaker bi-wiring offers improved sound quality because high and low frequency signals are carried
individually to the loudspeaker drive units.

Operating Modes
Although the 8000S is an integrated amplifier, it can function as a separate pre-amplifier and
power amplifier. This allows the unit to be used in a variety of stereo and multichannel modes.
NOTE: When switching modes, the making and breaking of connections may momentarily
operate the muting function on the 8000S.
The pre-amplifier section is internally connected to the power amplifier. Pre-amp outputs are
not operational. External subwoofers, processors, or amplifiers will not receive any signal.

Switching On
Make sure all the connections to and from the amp are secure and correct.
Make sure the operating mode is correctly set.
Plug the power cord into the wall socket and the amplifier. Switch on at the mains
and then switch on the 8000S. The power indicator lights. The unit is operational.
The amplifier may be operated via the front panel or the remote handset.
NOTE: Selecting MUTE from the front panel will disable the mute function on the
handset. To restore normal operation, select an operating mode.
