DISP (display) Cycles through the settings ‘Bright’, ‘Off’ and ‘Dim’. Turning the display ‘Off’ generally gives a slight improvement in sound quality. SELECT Performs same function as the SELECT button on the front panel. It allows you to use the remote’s volume switch in the same way you use the control dial on the front panel – to adjust various amplifier settings (see page 8). Note that pressing + corresponds to turning the Control knob clockwise, – to anticlockwise. ENTER Performs the same function as the ENTER button on the front panel (see page 6). 56 (UP and DOWN) These buttons do not apply to the A70. 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 chassis (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-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-amping in one length). How to bi-wire loudspeakers 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. Connect the cables as shown in the diagram below, ensuring correct polarity at all times. 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 integrated 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 A70 and the other an Arcam power amplifier (e.g. P90). 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 biamping in one length). Interconnect cables – one pair of high quality interconnect cables. 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. Connect the cables as shown in the diagram below, ensuring correct polarity at all times. 3. Use the interconnect cables to connect the PRE OUT sockets of the A70 to the corresponding AUDIO IN sockets of the power amplifier. .............................................................................................................................. .. .............................................................................................................................. .................................................................. A70 E 10 Bi-wiring using one set of connections on amplifier Recommended bi-amping configuration Service information Sound cuts out unexpectedly Before returning an amplifier for repair, please check the following: Heatsink protection If the temperature of the internal heatsink rises above a safe level, a thermal cutout inside the amplifier operates, the power indicator on the front panel flashes and the protection system temporarily removes 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 A70 at full power even though the volume is not set at maximum. Transformer protection The transformer is separately protected against thermal overload damage which may occur in exceptional circumstances. If the unit shuts down in ...
