ARCAM (MJ A28 Integrated Amplifier Key Features of the A28 Integrated Amplifier Pre-amplifier features • All electronic input switching for clean signal path and long term reliability • Studio grade volume control stage with +/- 0.05dB channel matching • Six line level inputs plus high quality MM phono input • Pre-amplifier outputs for bi-amping with Arcam power amplifiers (e.g.

input/auxiliary output When connecting a Compact Disc player with a phono socket output, a 5 pin 180° DIN plug (pins 3 & 5) to two PHONO plugs lead should be used. If the player is equipped with a fixed lead terminated in two phono plugs then a high quality twin PHONO sockets to 5 pin 180° DIN plug (pins 3 and 5) adaptor should be used (e.g. A & R lead type L02). If a tape recorder is being used in conjunction with this socket, then the lead required here is usually a 5 pin 180° DIN plug to 4

Avoid placing the unit in direct sunlight or near sources of heat or damp. Ensure adequate ventilation. Do not place the unit in an enclosed space such as a bookcase or cabinet as both of these will impede air flow through the ventilation slots. Connecting to loudspeakers Your amplifi er is fitted with loudspeaker terminals to BFA (British Federation of Audio) standard specification. BFA loudspeaker terminals The terminal will accept spade terminals, bare wires or a BFA plug. BFA plugs are avail

Volume control settings It is important to realise that the position of the Control knob is not an accurate indication of the power delivered to your loudspeakers. The amplifier often delivers its full power before the volume control reaches its maximum position, particularly when listening to heavily recorded compact discs. However the amplifier also has to be capable of giving full power output from much lower level sources, such as tuners and cassette decks. Using these sources, the volume co

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 A65 or A75 and the other an Arcam power amplifier (e.g. P75). Loudspeaker cables – one pair 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 cab

This is perfectly normal. If the unit is to be left unused for an extended period, we recommend that it is disconnected from the mains supply by switching it off at the wall socket, or by disconnecting the power lead. Connecting to other equipment The use of high quality interconnect cables to and from your amplifier is recommended to ensure the best sound quality. Sockets marked L (and R) on your amplifier should only be connected to sockets marked L (and R) on other equipment. All the line inp

These sockets will still accept bare wire or pin terminations. The “Camcon” connector will accept spade terminals, bare wires up to 4mm in diameter or a “Camcon” plug. “Camcon” plugs are available from your arcam dealer. ! ■ Connect your loudspeakers so that the red (positive; terminal on each loudspeaker is connected to the appropriate red terminal on the amplifier. Your loudspeaker cables may be clearly terminated to show polarity; if not, then the positive conductor can usually be identifi

You also need to make a connection from the preamp out sockets of your integrated amplifier, or preamplifier, to the power amp in sockets of the power amp. ADDING AN ALPHA 8P TO AN EXISTING ALPHA 7 OR 8 INTEGRATED AMPLIFIER If you are using an Alpha 7 or 8 amplifier, an Alpha 8P can be added to bi-amplify a pair of biwireable loudspeakers. This will reap substantial improvements in sound quality if the following advice is observed. ■ Always switch on the integrated amplifier and allow it to s

With a power amplifier of the correct gain (e.g. An Arcam Alpha 9P or 10P) this allows you to bi-amplify (“bi-amp”) suitable loudspeakers, giving significant improvements in sound quality (see section on BI-WIRING/ BI-AMPING). REMOTE CONTROL FUNCTIONS ■ Your Alpha 10 amplifier is supplied with the Arcam CR35 infra-red remote control handset, which has buttons to allow the simple operation of other products. It is supplied with 2 AA batteries - ensure these are inserted correctly. ■ The remote
