Bi-amping

Bi-amping requires the use of a second amplifier: one amplifier is used to drive the treble speakers, the other is used for the lower (bass) frequencies.

For the cables, bi-amping is much like bi-wiring. Connect the speaker terminals from one module (channel) to one pair of terminals on your speaker. Connect another module, or one channel of a separate power amp., to the other pair of terminals on the speaker, so that two amplifier channels are connected

to that speaker; one for low frequencies and one for high frequencies. The treble (higher) terminals of your speaker should be connected to the speaker terminals of the amplifier module (channel) being used for the high frequencies, while the bass (lower) terminals of your speaker should be connected to the speaker terminals of the amplifier or module (channel) being used for the lower frequencies. 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.

Notes on making speaker connections

<

<

<

<

Do not make any connections to your amplifier while it is switched on or connected to the mains supply.

Always ensure that the volume control on your pre-amplifier is set to minimum before starting to make connections.

Before switching your P1000 on for the first time after connecting to speakers, please check all connections thoroughly. Ensure that bare wires or cables are not touching the amplifier in the wrong places (which could cause short circuits), and that you have connected positive (+) to positive and negative (-) to negative.

After making connections, turn the volume down to minimum on your pre-amplifier before switching the P1000 on. 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. Your dealer will be happy to help you.

Setting the amplifier gain

You may have noticed a small switch next to the speaker terminals for each channel on the rear of the product. This switch allows the gain of the amplifier to be set: move the sliders to the A, B, or C position, depending on the gain value that you require.

A: This position means that the P1000 has a gain of 31.5dB, which is the usual gain for Arcam amplifiers. Use this setting if the P1000 is to be used either on its own, or in conjunction with other amplifiers from Arcam.

B: This gives the P1000 a gain of 29dB, which is the gain used by THX™-compatible amplifiers. Use this setting the P1000 is to be used with other amplifiers that have a THX™ gain value, such as the Arcam P7. Note that the P1000 is not a THX™-rated product.

C: This gives the P1000 a gain of 26dB. Use this setting if the P1000 is to be used with other amplifiers that have this gain.

Although the gain for each channel can be set independently, it is very unusual that different channels would be set to have different gains. We recommend strongly that you set all amplifier channels to the same gain setting.

Connecting to a power supply

Mains lead

The P1000 is normally supplied with a moulded mains-plug already fitted to the lead. If for any reason the plug needs to be removed, it must be disposed of immediately and securely, as it is a potential shock hazard when inserted into the mains socket.

Check that the plug supplied with the unit 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.

Should you require a new mains lead, or the voltage accepted by the unit does not match your supply, please contact your Arcam dealer.

Plugging in

Push the IEC-plug of the power cable supplied with the unit into the POWER INLET socket in the back of the unit. Make sure it is pushed in firmly.

Put the plug on the other end of the cable into your power supply socket and switch the socket on
