WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated `dangerous voltage' within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. [. . . ] If the C31 is switched off while the display is set to `off', the display will be set to `dimmed' when the C31 is switched on again. 9 REF - this toggles the volume display mode between `Standard', `Fine', and `Reference' (these are described on the next page. When the `Reference' volume display is selected, the light above the Ref button is illuminated. bk TRIM - gives direct access to the "Trim" menu item. C31/P38/P1 E-7 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. Press SELECT once to enter the configuration menu, then press it repeatedly to cycle through the menu items. When you have found the setting that you wish to adjust (the setting is shown on the display), it can be adjusted by using the control knob. Press ENTER to store the change you have made and return to default (volume) mode, or press SELECT again to move to the next setting. Note that the menu will time-out after a short period of inactivity, with the display reverting to the current volume. The following items are available for adjustment: Volume Resolution ­ There are three volume-display options to chose from: `Standard', `Fine' or `Reference'. Standard and Fine represent different levels of volume-control sensitivity; the Reference setting gives absolute increments in 0. 5dB steps. Input Trims ­ Input trims are used to compensate for variations in output levels of different source equipment. If, for example, your CD player is louder at a given volume display value than other inputs, you can attenuate it by using this setting so that it matches your other components. Use the source-select buttons to select the input you wish to adjust, then the control knob to set (increase or decrease) the input volume for that source. `On' Volume ­ This can be used to limit the maximum volume the amplifier operates at when it is first switched on: the C31 comes on at the (reduced) "Max. If this item is set to `Disabled', the C31 always comes on at the last used volume, even if this is very loud. Processor Mode ­ Processor mode enables you to fix the gain (volume setting) of your C31. The C31 (in combination with a power amp. ) can then be used to drive the front left and right speakers of a surround-sound system, when fed from a separate processor. The volume of the entire system can then be controlled using the processor. Feed the sound from the processor into the TAPE input, then set the gain of the C31 to match the amplifiers that drive your other loudspeakers. Reset ­ this restores all amplifier settings to their factory defaults. C31/P38/P1 E-8 CR-389 Remote Control 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 These buttons are used to control Arcam tuner functions.
