[. . . ] H A N DBOOK AVR250 Arcam AVR250 surround sound receiver English Français Deutsch Nederlands Safety guidelines CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN ATTENTION RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR CAUTION: To reduce the risk of electric shock, do not remove cover (or back). Refer servicing to qualified service personnel. 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. [. . . ] In comparison, some movie soundtracks can appear to be very quiet, as many directors like to keep the maximum levels in reserve for special effect sequences. The volume can be controlled over a range of 100dB in 1dB steps. Muting the volume Pressing the MUTE button will mute the output of the AVR250 to the speakers and from the `pre-amp out' connectors (the output to the record loops remains unaffected). `MUTE' will be shown on the display while in this state. Press MUTE for a second time (or adjust the volume) to exit the mute state. Front panel display In normal operation, the display shows the current volume setting, with the source shown on the lefthand side of the display. Smaller illuminated areas indicate the audio input type (digital or analogue) and the digital stream type (if applicable). If the processing mode changes (for example, from Dolby Pro Logic decoding to Dolby Digital 5. 1), then this will be displayed in large letters for about two seconds. Changing the display brightness It is possible to select the illumination level of the front panel display. Press DIS on the remote to cycle through the three illumination levels (Off/Dim/Bright). AVR250 E-19 English Input selection To select a particular source, press the corresponding button on the front panel or on the remote control. There are eight inputs available: DVD, Sat, AV, PVR, VCR, Tape, CD and DVD-A (multi-channel). In addition, AM and FM radio reception can be selected from the built-in tuner. Any picture signal associated with the selected input is switched to the monitor output. On selecting a source, the AVR250 will attempt to use the digital input in preference to an analogue input, assuming a digital signal is detected for the source. If you want to override the digital input and select the analogue input instead, however, this can be achieved by pressing and holding the button for the selected source for at least two seconds. The processing mode and `Stereo Direct' functions are remembered and recalled for each input. The digital input and high quality video input associated with each source may be configured in the device menus. The DVD-A input is intended for direct analogue pass-through of DVD Audio or SACD surround sources. Apart from volume control and level trim, no processing is performed on this input. Tape operation The TAPE button selects the audio from a cassette deck connected to the TAPE IN phono sockets of the AVR250. Pressing the TAPE button will select audio from the tape input; the TAPE LED will illuminate, together with the LED of the previously selected input. Illuminating the tape and source LEDs indicates that the tape loop is active and indicates the source that will be recorded. Example: If you want to record from the CD input: n n Select the CD input; Press the TAPE button ­ you can now listen to the sound returned from the recording device. In the case of a three-head cassette deck, this will be the audio as recorded onto the tape. Note that selecting a different source from CD will cause the recording to change to this new source. VCR/PVR Operation The AVR250 has VCR and PVR record loops for audio and video (Composite and S-video only). These are configured to allow recording of the source that you are watching. n n Pressing the VCR or PVR button selects audio and video from the VCR/PVR input. The VCR/PVR LED will illuminate, together with the LED of the previously selected input. Illuminating the VCR and source LEDs indicates that the tape loop is active and indicates the source that will be recorded. [. . . ] The returned frequency is calculated as follows: AM freq. (kHz) = (((1000's & 100's) ­ 0x30) * 100) + ((10's & 1's) ­ 0x30))) FM freq. (kHz) ­ 0x30) For these reasons, this command may return values that cannot be translated into ASCII characters.
