Bi-amping, P35 connected to speakers using bi-amping

Bi-amping

Bi-amping requires the use of a two amplifiers per channel: either two P35’s or four P1’s in a stereo system. One P35 (or two P1’s) is/are used to drive the high-frequency (treble) speakers, the other is used for the lower (bass) frequencies.

For the P35’s, connect one P35 to the speakers as described for single wiring, with the exception that the P35 should be connected to the speaker terminals labelled ‘HF’ or ‘High Frequency’. Then (in the same way), connect the second P35 to the low- frequency terminals. Please refer to the illustration.

For the P1’s: four P1 amplifiers are required for bi-amping two speakers. Two of the P1’s are used to drive high-frequency (treble) and two are used for the lower (bass) frequencies. Decide which amplifier is to drive which speaker element, then connect the amplifier to the speaker following the instructions given for single wiring.

Note that the strip of metal on the speakers connecting the lower terminals to the upper terminals must be removed. Failure to do so will result in damage to both amplifiers, which will not normally be covered under warranty.

Notes on making speaker connections

<Do not make any connections to any amplifier while it is switched on. We recommend that your amplifier is completely disconnected from the mains supply before starting.

<Before switching your amplifier(s) on for the first time after connecting to speakers, please check all connections thoroughly. Ensure that bare wires or cables are not touching each other or the amplifier’s chassis (which could cause short circuits), and that you have connected positive (+) to positive and negative (–) to negative. Be sure to check the wiring for both the amplifier and the speaker.

<After making connections: switch the amplifier(s) on, select a source signal, then gradually increase the volume to the required listening level.

<If you are unsure as to how your system should be connected, or need advice on bi-wiring or bi- amping, please contact your Arcam dealer who will be happy to help you.

Connecting to a power supply

Mains lead

Your amplifier is normally supplied with a moulded mains plug already fitted to the lead. Check that the plug fits your supply and that your mains supply voltage agrees with the voltage setting (115V or 230V) indicated on the rear panel of the unit before plugging in.

If your mains supply voltage or mains plug is different, please consult your Arcam dealer immediately.

Plugging in

Push the IEC-plug of the power cable into the socket POWER INLET on the back of the unit, making sure it is pushed in firmly.

Stand-by power

For remote stand-by operation, the amplifier’s control power supply is kept powered-up all the time the unit is connected to the mains supply. The front-panel power-switch powers down all other circuitry and power consumption in this mode is less than 2W.

This means that even though the power switch is off, it may be possible to hear a slight residual hum coming from the mains transformer inside the amplifier. This is perfectly normal. If the unit is to be left unused for an extended period, however, we recommend that it is disconnected from the mains supply.
