A80/P80 2 Installation: P80 power amplifer SP2 TRIG OUT AUDIO LINK 4 ­ 16 OHMS SP1 VOLTAGE SELECT L R POWER INLET REMOTE IN 115/230V + R ­ + L ­ IN OUT Connecting to power, loudspeakers and other equipment Follow the installation instructions for the amplifier on pages 4­6. Remote switching By making a connection from the REMOTE IN socket of the P80 power amplifier to the TRIG OUT socket of the A80 amplifier, you can use the A80 to switch the power amplifier on and off. If configured in this way, the front panel POWER button of the A80 (or the Power/Standby button on the remote control) switches both amplifiers on and off together. This facility allows you to conceal the power amplifier yet still control it. The connecting cable required is a male 3.5mm to male 3.5mm jack lead (stereo or mono) and it is possible to connect several power amplifiers to an A80 by `daisy chaining' from TRIG OUT of one P80 into the REMOTE IN of the next. AUDIO IN Connect this input to the output sockets of your pre-amplifier or the PRE OUT sockets of an amplifier. MONO LINK The power amplifier can be adapted to provide two mono loudspeaker outputs from a single input. Pull out the link supplied and use it to connect the L and R AUDIO OUT sockets together. Using one power amplifier per loudspeaker will enable you to bi-amplify bi-wireable loudspeakers. This is particularly beneficial for top quality stereo installations with a separate pre-amplifier, or where amplifiers are provided for the left, centre and right channel loudspeakers in a five speaker Dolby Pro Logic or Dolby Digital system. Contact your Arcam dealer for more information. Signal detect The P80 power amplifier features a signal-detecting circuit that automatically switches the unit on when an input signal is delivered to the amplifier. The unit switches into standby approximately 12 minutes after the signal source is switched off. The signal detect feature is disabled by the supplied blank plug, or when a connection from the REMOTE IN socket to TRIG OUT of an A80 is made. Simply remove the blank plug from the REMOTE IN socket if you wish to use this feature. `Daisy chaining' The power amplifier can be connected to further power amplifiers to drive more speakers (e.g. those in other rooms or tri-amplified speakers, etc). Connect the extra power amplifier inputs to the AUDIO OUT sockets on the power amplifier, left to left, right to right. A80/P80 10 Using your P80 power amplifier A80 POWER AMPLIFIER SP1 SP2 POWER 1 2 POWER (and power indicator light) 2 SP1 and SP2 1 Switches the unit on and off. The light indicates the status of the amplifier. When you switch your amplifier on, the light glows amber for a few seconds, during which time the speakers are disconnected. The light changes to green when the amplifier is ready for use. A red light means the amplifier is in standby mode. The light may flash if a fault has occurred somewhere in the system (the fault type is shown on the front panel display of the A80). You should unplug the amplifier and leave it for a few minutes before reconnecting. If the fault cannot be cleared, unplug your amplifier and contact your Arcam dealer. These buttons allow you to select and deselect the main (SP1) and secondary (SP2) sets of speakers attached to your amplifier. NOTE: If both lights are out the amplifier will appear not to work, as all speakers are switched off. If both are on, overloads are more likely if low impedance speakers are connected. A80/P80 11 Bi-wiring and bi-amping loudspeakers Before you start WARNING: Do not make any connections to your amplifier while it is switched on or connected to the mains supply. Before switching on please check all connections thoroughly, making sure bare wires or cables are not touching the amplifier in the wrong places (which could cause short circuits) and you have connected positive (+) to positive and negative (­) to negative. Always ensure that the volume control on your amplifier is set to minimum before starting these procedures. Bi-amping your system The performance of your system can be further enhanced over that achieved with bi-wiring, by extending the principle one stage further to include separate amplification for the low and high frequency drive units in each loudspeaker enclosure. Connect the amplifier to the high frequency (HF) terminals and connect the power amplifier to the low frequency (LF) terminals. You will need: Speakers ­ with four input terminals each (as with bi-wiring): these will be marked HF (High Frequency) and LF (Low Frequency). Two amplifiers ­ one of these would be the A80 and the other an Arcam power amplifier (e.g. P80). Loudspeaker cables ­ two pairs of cables per loudspeaker or a suitably terminated cable set (a loom, probably prepared by your dealer and capable of being used for bi-amping in one length). Interconnect cables ­ one pair of high quality interconnect cables. Bi-wiring your loudspeakers Bi-wiring improves the sound of your system because it divides the high and low frequency signal currents into separate speaker cables. This avoids signal distortions arising from the high and low frequency currents interacting with one another within a single cable, as in conventionally wired systems. You will need: Speakers ­ with four input terminals each: these will be marked HF (High Frequency) and LF (Low Frequency). Loudspeaker cables ­ two pairs of cables per loudspeaker (which may be joined at the amplifier end if your amplifier has only one pair of output terminals per channel). Or, a suitably terminated cable set (a loom, probably prepared by your dealer and capable of being used for bi-wiring in one length). How to set up a bi-amped system 1. Remove the terminal links on the rear of your loudspeakers. WARNING: This step is essential or damage to your amplifier may result which is not covered under warranty. 2. 3. Connect the cables as shown in the diagram below, ensuring correct polarity at all times. Use the interconnect cables to connect the PRE OUT sockets of the A80 to the corresponding AUDIO IN sockets of the power amplifier. How to bi-wire loudspeakers 1.

The power indicator on the front panel flashes and the protection system temporarily removes the power to the speakers. The system resets after the heatsink has cooled down. Note that because of the high output voltage from a CD player, it is possible to drive the A80 at full power even though the volume is not set at maximum. Amplifier does not switch back on The A80 and P80 amplifiers have a protection mechanism which is activated if you switch the unit on immediately after turning it off. If this mechanism activates, wait 30 seconds then switch back on again.
