Thank you for buying this quality Arcam product. This handbook covers the following items: < < < C31 pre-amplifier; P35 power amplifier; P1 power amplifier. This handbook is intended to give you all the information you need to install and use these products. The C31 is described first, followed by the P35 and the P1. Use of the CR-389 remote control supplied with the C31 is also described.

Avoid placing the unit in direct sunlight or near sources of heat or damp. Ensure adequate ventilation.
Recording loops The C31 is equipped with two recording loops, for use with recording devices (such as cassette decks, MiniDisc players, VCR’s etc.) 7 TAPE/PROC RECORD OUT – Connect these output sockets to the input sockets of your recording device (usually labelled RECORD or IN). English 8 TAPE/PROC PLAY IN – Connect the output sockets of your recording device (usually labelled PLAY or OUT) to these inputs.

The power light (next to the “C31 Pre-Amplifier” text) indicates the state of the amplifier: 1.
Recording an audio source The C31 allows listening to and recording from the same source, or listening to one source whilst recording another. The signal to be recorded is sent to both the TAPE and VCR output sockets. Selecting the source for recording The recording outputs can be configured in two ways: English 1. to allow recording of the source being listened to; 2. to allow recording of a particular (specified) source, regardless of what is being listened to.
Configuring your C31 pre-amplifier Introduction The C31 allows you to customise various features of the amplifier to fit your system. Use this diagram to help you navigate through the available configuration options. In the diagram below, the ENTER and SELECT buttons from the front panel are represented by the symbols and respectively. The control knob is shown as . Adjusting listening settings Normally, the display shows the current volume and the control knob is used to adjust this.
Using the remote control CR-389 Remote Control English The CR-389 remote control gives access to all functions available on the front panel of the C31. It also has controls to operate Arcam CD players and tuners. TUNER TUNER These buttons are used to control Arcam tuner functions. Note that the FM/DAB lights indicate into which mode you are switching the remote control. The lights only illuminate for five seconds to conserve battery power.

Amplifier Gain Switch (P1) This switch is to allow the gain of the P1 amplifier to be changed to suit your system requirements. With the switch in, the gain is set to standard ARCAM gain of 31.5dB. This is the normal setting, which allows the P1 to be used in systems where there are other ARCAM power amplifiers (excluding the Arcam P7). English With the switch out, the gain is set to ‘THX standard gain’.
Connecting loudspeakers Wiring strategies There are three different wiring strategies that can be employed to connect your amplifier to your speakers. The choice will be limited by what your speakers can support. < Single wiring Single wiring is the conventional wiring method of running a single cable per channel between the amplifier and the speaker. This is the easiest technique.
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 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.
Using your power amplifier P35 POWER AMPLIFIER SP1 SP2 POWER P35 Power Amplifier: Front panel P1 POWER AMPLIFIER POWER P1 Power Amplifier: Front panel POWER button Switches the unit on and off. The light indicates the status of the amplifier. When you switch your amplifier on, the light glows amber for a few seconds, during which time the speakers are disconnected. The light changes to green when the amplifier is ready for use. A red light means the amplifier is in stand-by mode.

Troubleshooting If you are having trouble with your amplifier, check the following items. English No sound Check the following: < < < < < Both the pre- and power-amplifiers are switched on. The pre-amp. is not muted (indicated on the C31 by “Muted” being shown on the front-panel). The selected source is generating audio (e.g., if CD is selected, then the CD is playing).
