Switches the unit between Standby mode (indicated by dim power LED) and On (indicated by bright power LED). Standby is a low power mode where the power consumption is less than 10 Watts. The unit should be left in Standby mode when not in use.
Note: As default the 840A V2 ramps the volume up or down when switched on and when going into Standby mode. This feature can be turned off if desired; please refer to the ‘Amplifier setup’ section of this manual for more information.
2Phones
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).
3Speaker 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 one pair of speakers, use speakers with a nominal impedance of between
4Mode
Press to switch between Volume and Balance modes. Press and hold to to enter the 840A V2 System Configure menu.
LCD used to control the 840A V2. Please refer to the ‘Operating instructions’ and ‘Amplifier setup’ section of this manual for more information.
9Bass and Treble
Press to release and rotate to allow subtle adjustments to the tonal balance of the sound.
10Direct
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 ( 
) 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 settting is recalled each time a source is selected.
11Volume
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
As the 840A V2 uses a very high quality passive resistor ladder switched by relays to achieve volume and balance, audible control clicks can be heard from the unit when the volume or balance is adjusted.
The Volume control is also used in navigating the 840A V2 System Configure menus on the front panel display.
5Infrared 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 Input 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 Tape 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 tape input Tape Monitor).
Please refer to the ‘Operating instructions’ section of this manual for more information on some functions of these buttons.
