D6 Amplifier, Hardware manual
Status indication
The switch incorporates a green LED indicator which indicates three
different states – ON, MUTE and STANDBY.
- LED illuminates permanently ⇒ ON (unmuted)
The D6 is ready for use.
- LED regular flashing (1:1 duty cycle): ⇒ MUTE
The corresponding channel of the D6 is muted however the power
amplifiers remain powered but receive no signal from the controller.
A connected loudspeaker is therefore still damped.
- Regular short flashes (1:8 duty cycle): ⇒ STANDBY
In Standby mode the loudspeaker outputs are electronically isolated
and the D6 idles, drawing minimal mains power. Only the most
essential functions are provided. Display and network remain
functional, the display illumination will be switched off after 10 s.
Note: When the D6 is set to STANDBY (or the mains power is turned
off) the movement of the loudspeaker cones in the cabinets connected is
no longer damped by the power amplifier output. This removal of the
damping makes them susceptible to excitation by other loudspeakers in
the surroundings. Audible resonances may occur, and even absorption
of low frequency sound energy as the undamped loudspeakers act like
a "bass trap". To permanently mute single subwoofer cabinets when
others are operated at the same time it is therefore preferable to use
the MUTE function instead of STANDBY. The Standby mode, however,
can be of advantage with mid/high systems, because it will remove any
residual noise from the system.
3.1.3. LEVEL/PUSH MENU (Digital rotary encoder)
Operation, configuration and status viewing of the D6 are all accessed
via the front panel digital rotary encoder - LEVEL/PUSH MENU [3]. In
the main menu the encoder acts as a level control. Pushing or turning
the encoder gives access to different menu levels or enables
configurations or values to be entered.
Brief press
Alternating between level control of channel A or B.
Long press (approx. 1 s)
Access to the menu level. A detailed description of the D6 menu
structure and access is given in the D6 Software manual, which is also
provided with the D6.
