[. . . ] AVR600 Handbook AVR surround amplifier English Class II product This equipment is a Class II or double insulated electrical appliance. It has been designed in such a way that it does not require a safety connection to electrical earth (`ground' in the U. S. ). safety guidelines 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. [. . . ] Treble ­ Bass ­ These allow you to alter the bass and treble tone controls for all currently active speakers for each individual Room EQ ­ When the Auto Speaker Setup function is run it also calculates Room Equalisation coefficients to remove some of the worst effects of resonant frequencies of the room at the listening position. By default Room EQ is not applied to any of the source inputs, however you can enable them on a per-input basis as you wish. < Not Calculated: (Information only) Auto Speaker Setup has not been run or has errors so cannot be selected. < On: Room EQ is applied to the current source. < Off: Room EQ is not applied to the current source. Input Trim ­ Sets the maximum analogue input signal level (sensitivity) on this input before the ADC (Analogue-to-Digital converter) signal path clips. Options are 0. 5, 1, 2 and 4 volts RMS maximum input. For example, analogue sources with low output levels may benefit by choosing the 1V maximum setting, or the 0. 5V maximum setting if the source has a very low output. This helps maximise signal-to-noise performance of the AVR600 and also helps keep the various analogue sources sounding about the same level for any given AVR600 volume control setting. Dolby Volume ­Dolby Volume is an intelligent system that improves the perceived audio frequency response at lower listening levels and corrects for volume inconsistencies between sources (e. g. a rock radio station and a DVD) and between programming (e. g. < Off: (default) Dolby Volume is not applied to this input. < Cinema: enables Dolby Volume for this source and configures the input for audio which comes mostly from movie soundtracks. < Music: enables Dolby Volume for this source and configures the input for audio which comes from other sources (CD, TV, Satellite, Tuner, etc. ). Dolby Leveller ­ This setting of Dolby Volume controls how closely quiet and loud sources and programme content are matched to each other, based on the ear's perception of loudness. The range of values is 0 (minimal levelling) to 10 (maximum levelling). The default setting is 9, however we recommend < DV Calib. Offset ­ The Calibration Offset parameter of Dolby Volume allows you to compensate for speaker efficiencies and listening position. The default value is 0 and this should normally produce a good result when the AVR600 speaker levels are set using a sound pressure level meter. See the Dolby Volume section on page 42 for further information on Calibration Offset. Surround EX ­ Sets how the AVR600 should configure its decode mode when a Dolby Digital EX bitstream is received. Note that this setting only applies if you have Surround Back loudspeakers. [. . . ] < sometimes Dolby Digital DVD discs contain material at either the beginning or the end of the main movie that is not in full 5. 1 format, but in twochannel or Pro Logic decoding. < all cables are making a good connection. If necessary withdraw the cable from the connector and plug it fully in again (turn the power off before doing this). < the connections inside the source cable connector are not broken or badly soldered. < if the hum originates only when one particular source component is connected, that an aerial cable, or dish connection to this source is ground isolated.
