Single wiring

The A28 is designed for bi-wiring, which is why there are duplicate speaker terminals on the back. For

single wiring, we recommend that you use the lower set of speaker terminals on your amplifier. If each

speaker has more than one pair of connecting terminals, use the terminals labelled

for each speaker.

Connect the positive terminal of the right speaker connection on the amplifier (coloured red and labelled

) to the positive terminal of your right speaker. Similarly, connect the negative terminal of the amplifier

(coloured black and labelled with

) to the negative terminal of your speaker. Repeat the process for the left

R–

speaker, using the amplifier terminals labelled

and

If your speakers support bi-wiring, then there is a strip of conductive metal on the speakers connecting the

low-frequency terminals to those for the higher-frequencies; this mUST NOT be RemOVeD in a single-

wired system.

bi-wiring

Bi-wiring is performed in the same way as single wiring except that, for each speaker, a pair of cables are

used to connect the amplifier to each speaker.

Follow the instructions given for single wiring; then perform the same actions, this time connecting the

upper set of speaker terminals on your amplifier to the terminals labelled

speaker. Please refer to the illustration.

Speakers that support bi-wiring have a strip of metal on the speakers connecting the low-frequency

terminals to those for the higher-frequencies; this mUST be RemOVeD in a bi-wired system.

bi-amping

Bi-amping requires the use of two amplifiers per channel. Normally, your A28 is used to drive the high-

frequency (treble) speakers, while a power-amplifier (such as a P38) is used for the lower (bass) frequencies.

Connect your A28 to the speakers as described for single wiring, with the exception that the A28 should be

connected to the speaker terminals labelled

or 'High Frequency' . Then connect the power amplifier (P38,

for example) to the

or 'Low Frequency' terminals, as in the diagram. A pair of audio interconnect cables

are also required to connect the pre-amp outputs of the A28 to the power amp inputs of the P38.

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.
