[. . . ] All other servicing should be referred to qualified service personnel. Damage requiring service The appliance should be serviced by qualified service personnel when: A. the power-supply cord or the plug has been damaged, or objects have fallen, or liquid has spilled into the appliance, or the appliance has been exposed to rain, or the appliance does not appear to operate normally or exhibits a marked change in performance, or the appliance has been dropped or the enclosure damaged. CAUTION: To reduce the risk of electric shock, do not remove cover (or back). WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. [. . . ] Racks and stands Only use a rack or stand that is recommended for use with audio equipment. If the equipment is on a portable rack it should be moved with great care, to avoid overturning the combination. A90/P90 2 Safety compliance This product has been designed to meet the IEC 60065 international electrical safety standard. Installation: P90 power amplifer + R/CH1 ­ + L/CH2 ­ SP2 AUDIO LINK + CTR/CH3 ­ SP2 CTR/CH3 TRIG OUT VOLTAGE SELECT 230V 4 ­ 16 OHMS SP1 L R SP1 IN OUT 4 ­ 16 OHMS AUDIO IN REMOTE IN OUT POWER INLET + R/CH1 ­ + L/CH2 ­ + CTR/CH3 ­ Optional Third Channel Module ­ provides a third 90W channel suitable for Home Cinema or multi-channel audio use. Connecting to power, loudspeakers and other equipment Follow the installation instructions for the integrated amplifier on pages 4 and 5. AUDIO IN ­ Connect this input to the output sockets of your pre- Remote switching By making a connection from the REMOTE IN socket of the P90 power amplifier to the TRIG OUT socket of the A90 integrated amplifier, you can use the A90 to switch the power amplifier on and off. If configured in this way, the front panel POWER button of the A90 (or the POWER/STANDBY button on the remote control) switches both amplifiers on and off together. This facility allows you to conceal the power amplifier yet still control it. The connecting cable required is a 3. 5mm to 3. 5mm jack lead (stereo or mono) and it is possible to connect several power amplifiers to an A90 by `daisy chaining' from TRIG OUT of one P90 into the REMOTE IN of the next. amplifier or the PRE OUT sockets of an integrated amplifier. MONO LINK ­ The power amplifier can be adapted to provide two mono loudspeaker outputs from a single input. Pull out the link supplied and use it to connect the L and R AUDIO OUT sockets together. Using one power amplifier per loudspeaker will enable you to bi-amplify bi-wireable loudspeakers. This is particularly beneficial for top quality stereo installations with a separate pre-amplifier, or where amplifiers are provided for the left, centre and right channel loudspeakers in a five speaker Dolby Pro Logic or Dolby Digital system. "Daisy chaining" ­ The power amplifier can be connected to further power amplifiers to drive more speakers (e. g. Connect the extra power amplifier inputs to the AUDIO OUT sockets on the power amplifier, left to left, right to right. Three channel option The power amplifier can be upgraded from stereo to three channels by adding a Third Channel Module: in this case, the model is designated P90/3. The module offers extra loudspeaker terminals together with a third set of AUDIO IN and OUT phono sockets and converts the P90 into a 3 x 90W (RMS per channel into 8) amplifier suitable for Home Cinema or multi-channel audio use.

When you switch your amplifier on, the light glows amber for a few seconds, during which time the speakers are disconnected. The power light may flash if a fault has occurred, with the colour of the flashing light indicating the nature of the fault: green ­ a D. C. offset fault has occured amber ­ a thermal fault has occured (the amplifier is too hot) red ­ a short circuit fault has occured (this can happen if the speaker cables are not connected correctly and are making contact with each other or with the chassis) red and amber ­ more than one fault has occured. Except for a thermal fault, if one of the above faults is detected by your amplifier the unit waits for six seconds before checking to see if the fault has cleared. If the fault clears within six seconds, then the unit continues operation; otherwise the unit shuts itself down. In the case of a thermal fault, the unit waits until its sensor temperature lowers before resuming operation. SP1 and SP2 These buttons allow you to select and deselect the main (SP1) and secondary (SP2) sets of speakers attached to your amplifier. An indicator light shows which set of speakers are currently selected. [. . . ] 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. 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. This means that designs and specifications are subject to change without notice. NOTE: All specification values are typical unless otherwise stated.
