If the equipment is on a portable rack it should be moved with great care, to avoid overturning the combination. 8. Cleaning Unplug a unit from the mains power supply before cleaning. The cases should normally only require a wipe with a soft, damp, lint-free cloth. Do not use paint thinners or other chemical solvents for cleaning. We do not advise the use of furniture cleaning sprays or polishes as they can cause indelible white marks if the unit is subsequently wiped with a damp cloth. 9. Power sources Only connect an unit to a power supply of the type described in the operating instructions or as marked on the product itself. The primary method of isolating these products from the mains supply is to remove the mains lead from the rear of the unit. These products must be installed in manner that makes this disconnection possible. These are Class 1 devices and must be earthed. 10. Power-cord protection Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention to cords and plugs, and the point where they exit from the unit. 11. Grounding Ensure that the grounding means of these products is not defeated. 12. Power lines Locate any outdoor antenna/aerial away from power lines. 13. Non-use periods When using the stand-by function, a small amount of current will continue to flow into the unit. Unplug the power cord of a unit from the outlet if it is to be left unused for a long period of time. 14. Abnormal smell If an abnormal smell or smoke is detected from a unit, turn the power off immediately and unplug the unit from the wall outlet. Contact your dealer for further advice. 15. Servicing You should not attempt to service these products beyond that described in this handbook. All other servicing should be referred to qualified service personnel. 16. Damage requiring service These products should be serviced by qualified service personnel when: A. the power-supply cord or the plug has been damaged, or B. objects have fallen, or liquid has spilled into the appliance, or C. the appliance has been exposed to rain, or D. the appliance does not appear to operate normally or exhibits a marked change in performance, or E. the appliance has been dropped or the enclosure damaged. Safety compliance These products have been designed to meet the IEC 60065 international electrical safety standard. C31/P38/P1 E-2 Thank you for buying this quality Arcam product.

E-16 n n n C31 pre-amplifier; P38 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 P38 and the P1. Use of the CR-389 remote control supplied with the C31 is also described. If your amplifiers have been installed and set-up by an authorised Arcam dealer, you may wish to go directly to the sections on how to use this equipment. Otherwise we recommend reading carefully the installation instructions for your products before proceeding. Safety Safety guidelines are set out on page 2 of this handbook. Many of these items are common-sense precautions but, for your own safety and to ensure that you do not damage the unit, we recommend that you read them. Environmental matters: This handbook is printed in the U.K. on recycled paper, and is itself fully recyclable and biodegradeable. The paper used is from the `Revive' range of papers, manufactured in the U.K. by Robert Horne. In Revive, 75% of the paper is de-inked post-consumer waste, with the remaining 25% being mill broke and virgin fibre. The recycled pulps used in the production of this paper are a combination of Totally Chlorine Free (TCF) giving zero AOX and Elemental Chlorine Free (ECF) giving a resultant AOX level of less than 0.5Kg per 1000Kg of pulp.

Do not place the unit in an enclosed space such as a bookcase or cabinet as both of these will impede air-flow through the unit. Connecting to other equipment The connections on the rear of the C31 fall into four groups: 1. dedicated audio inputs; 2. recording loops; 3. connections for power-amplifiers; 4. remote control and trigger connections. These groups are described below. General advice on connecting to other equipment n We recommend the use of high-quality interconnect cables to and from your amplifier to ensure the n Make sure that audio and power cables are kept as far apart from each other as possible. This reduces the risk of `noise' from the power cables bleeding into those for audio. best sound quality; cheap `bell-wire' interconnects may seem to be a good alternative, but they will reduce the overall quality of your system, and are a false economy. n n For each of the audio inputs/outputs that you wish to use, connect the terminal labelled L or LEFT (on Cables should be kept as short as is practical. the device to be connected) to the terminal labelled L for that input/output on the C31. Similarly, the terminal labelled R or RIGHT on the device should be connected to the R-terminal on the C31. Conventionally, stereo-phono leads have plugs that are coloured red for the right channel and white or black for the left channel, to aid channel identification. Audio inputs bl DVD ­ This input is intended for use with a DVD-player. Connect the stereo audio outputs of your DVD player to these sockets. bm AV ­ This input is intended for use with general audio-visual equipment, such as a VCR, digital TV/satellite receiver, or Nicam tuner. Connect the analogue audio outputs of the device to this input. bn TUNER ­ Intended for use with a radio tuner. bo CD ­ Intended for use with a CD-player. bp AUX ­ As with the `AV' input, this is intended for general use. Connect the audio outputs of any unit with a line-level output (tape deck, tuner, etc.), to this input. bq PHONO (if fitted) ­ As standard, no phono input is fitted to the C31. Phono inputs are provided on a separate plug-in module which your Arcam dealer or distributor can supply and fit. This module is compatible with most high-output moving-coil and moving-magnet cartridges (MM) and low-output moving-coil cartridges (MC). Once the module is fitted, MM or MC is selected via the MM/MC back panel switch. Why is this useful? The phono module (or an external phono amplifier) is required if you wish to connect a record player to the C31. This is because the low-voltage output of a record player requires a pre-amplification stage before the signal can be used. If you have already an external phono amplifier that you wish to use, connect this to one of the line-level inputs, such as the `AV' input. With the exception of the `phono' input, although these inputs are labelled for specific devices, all have the same characteristics and each may be used with any line-level product. The AUX input must not be used if the phono module is fitted. When this is fitted, AUX becomes an output carrying the phono signal at line-level. C31/P38/P1 E-4 Recording loops 7 TAPE/PROC RECORD OUT ­ Connect these output sockets to the input sockets of your recording device (usually labelled RECORD or IN). 8 TAPE/PROC PLAY IN ­ Connect the output sockets of your recording device (usually labelled PLAY or OUT) to these inputs. If you do not have a recording device, you can use this input for other (line-level) equipment, such as a CD-player, tuner, VCR, etc. second recording device. 9 VCR/TAPE2 RECORD OUT ­ These output sockets can be connected to the input sockets of a bk VCR/TAPE2 PLAY IN ­ Connect the output sockets of your second recording device to these inputs.
