[. . . ] Please refer to the ‘Operating instructions’ and ‘Amplifier setup’ section of this manual for more information. 9 Bass and Treble Press to release and rotate to allow subtle adjustments to the tonal balance of the sound. 10 Phones Direct Allows for the connection of stereo headphones with a ¼” Jack plug. Headphones with an impedance of between 32 and 600 ohms are recommended. When the headphones are connected, the loudspeaker relays are released switching off the output to the loudspeakers (speakers A and B). 3 This control gives the audio signal a more direct path to the power amplifier stage of your amplifier, bypassing the tone control circuits for the purest possible sound quality. The Bass/Treble icon (b t) appears in the display when the bass and treble circuit is active (in circuit) and is not present when they are bypassed. Note: Direct can be set on or off individually for each input. This setting is recalled each time a source is selected. 11 Speaker A/B Press to scroll through the speaker sets connected to the loudspeaker terminals on the back panel (speaker sets A, B or A and B). This can be used for listening to an extra set of loudspeakers in another room. Please note that care should be taken when choosing speakers if two loudspeakers are going to be used on each channel. If the combined resistance measured on the loudspeaker terminals is too low the amplifier may not switch out of Standby mode until a suitable load resistance is detected. For more information refer to the CAP5 section of this manual. Note: When using two pairs of speakers, use speakers with a minimum nominal impedance of 16 ohms. 4 Volume Use to increase/decrease the level of the sound from the outputs of the amplifier. This control affects the level of the loudspeaker output, the pre-amp output and the headphone output. It does not affect the Tape Out connections. The Volume control is also used in navigating the 851A System Configure menus on the front panel display. Please refer to the ‘Operating instructions’ section of this manual for more information on some functions of these buttons. Mode Press to switch between Volume and Balance modes. Press and hold to enter the 851A System Configure menu. 5 Infrared sensor Receives IR commands from the supplied Azur remote control. A clear unobstructed line of sight between the remote control and the sensor is required. 6 & 7 Source select buttons Push the appropriate input selection button to select the source component that you wish to listen to (highlighted by a solid circle on the display). The signal selected is also fed to the Rec Out sockets so that it may be recorded. The input should not be changed whilst recording (but the recorded signal can be checked using the Rec input). Note: Repeatedly pressing the Source 1 or Source 2 buttons will toggle these inputs between ‘Balanced’ and ‘Unbalanced’ source input. 6 azur Remote control The 851A is supplied with an Azur Navigator remote control handset that duplicates the front panel control functions and is also able to control Azur CD players and in particular the matching 851C. The supplied AAA batteries must be fitted before the remore control can be used. The Azur handset buttons function as described in the following paragraphs. [. . . ] Commands on this input operate the unit only and are not looped out demodulated on the Control Bus Output. An RS232C port is also featured which allows the 851A to be controlled by C. I. In addition the units feature ‘direct’ IR/Control codes as well as toggle codes for some of their features to simplify programming custom installation systems. Special direct On/Off and Mute commands can be accessed on the supplied remote control for teaching into C. I. [. . . ]
