Operation

Settings Menu

The Reference 6 has been designed 

with a simple, intuitive menu to allow 

adjustment of the various features of 

the preamplifier. To adjust the settings, 

press the ‘MENU’ button on the remote 

or front panel. If no further action is taken 

with the preamplifier or remote for five 

seconds, the Reference 6 reverts back to 

its normal operation screen. Continuing 

to press the ‘Menu’ button will toggle you 

through the different setting options: 

While a menu item is displayed, press 

‘ENTER’, followed by rotating the 

volume knob on the front panel, or 

using the volume up/down buttons on 

the remote to adjust the settings of 

that particular selecton. After making 

the appropriate change, pressing the 

‘ENTER’ button will confirm the new 

setting, and the display will show ‘OKAY’ 

for five seconds before reverting back 

to the normal operation screen.

Note

For the following menu settings, please refer 

to the menu tree on page 14 for examples 

of the front panel display.

Both the ‘MENU’ and ‘ENTER’ buttons (found 

on the front panel and remote), as well as 

the volume knob (or the up/down volume 

buttons on the remote) are used to make 

changes to the menu settings. Note that 

the ‘MENU’ button can also be used to 

back out of a menu selection, returning to 

the main settings options.

Auto Shutdown

The Reference 6 is equipped with an auto 

shut off feature, designed to turn the 

preamplifier off after a period of time 

during which it is not used. The auto shut 

off feature senses any interaction with 

the preamplifier, such as button presses, 

changing the volume, remote usage, etc.

To change/disengage the auto shutdown 

feature, press the ‘MENU’ button 

until the ‘AUTO SHUTDOWN’ screen 

is displayed. Using the volume knob 

on the front panel, or the volume up/

down buttons on the remote, you have 

the option for ‘off’ (no auto shutdown) 

or 1-8 hours. Once you have made a 

selection, press ‘ENTER’ to confirm. The 

display will show ‘OKAY’ before reverting 

back to the normal operation screen.

Note

The auto shutdown feature is not in the 

signal path of the preamplifier and has no 

deleterious sonic effect to music playback.
