There are two settings for the AUTO switch:
1) AUTO
The subwoofer can be turned ON and OFF using the Remote Control, UNLESS there
is a signal present – in which case the 3-segment DALI display will flash ‘ON’ to
indicate a signal is present. When the main power switch is on, the subwoofer
amplifier will turn on whenever an input signal is detected on one of the line inputs.
When a signal is not detected for approximately 20 minutes, the subwoofer amplifier
will automatically go into standby-mode.
2) MANUAL The subwoofer can ONLY be turned ON and OFF by using the Remote Control.
P O W E R
The POWER button is the main ON/OFF switch. We recommend switching OFF the system when
it is not to be used for long periods. When changing connections, always disconnect the mains
voltage to the subwoofer. We recommend that you ALWAYS turn off the DALI MENTOR SUB with
the Remote Control BEFORE turning off the mains switch.

If DALI MENTOR SUB is overloaded, the built-in safety circuit will cut the power off. If this occurs
let it cool down before turning it back on. The built-in safety circuit is not a guarantee against
damage as a result of overloading.

Clean the cabinet with a soft, dry micro-fibre cloth. If the cabinet is dirty, wipe with a soft, damp
(well-wrung) micro-fibre cloth with mild all-purpose cleaner.

The surfaces of the subwoofer are made of wood veneer, which are sensitive to sunlight.
Therefore the surface may fade over time. To reduce colour fading, avoid exposing the subwoofer
to direct sunlight.

First push VOL and then adjust the volume by pr or - so that the bass matches the level
of the main speakers (Level range 0-30 dB). You should be able to appreciate the DALI MENTOR
SUB's contribution to the sound, without it ever being over-powering. Bass must be tight and
accurate, so that the subwoofer reproduces the exact amount of bass present in the music/
soundtrack, no more no less. If installing the DALI MENTOR SUB in a surround system, it is
practical to select a fixed level on the DALI MENTOR SUB and adjust subwoofer output using the
surround (pre-)amplifier's setup function.
If bass levels are set too high, distortion will reduce the quality of your listening experience. Please
note that the position of the subwoofer will have major influence on its sonic contribution.
C R O S S O V E R F R E Q U E N C Y A D J U S T M E N T
The crossover frequency adjustment is only necessary when using the LEFT/RIGHT line inputs.
Once the volume level is decided, you can start on the equally important adjustment of the over-
lap between the main speakers and the DALI MENTOR SUB. First press FREQ and then adjust using
+ or - until you can hear that the bass is even and with no drop-outs (Frequency range 40-120
Hz). You may have to re-adjust the volume again to optimise performance.
P H A S E A D J U S T M E N T
First press PHASE and use + or - to toggle between the 0°, 90°, 180° or 270° phase settings. Try out
different settings and if necessary re-adjust the VOLUME and CROSSOVER frequency. Select the
position that provides the smoothest transition between the main speakers and the subwoofer. The
choice may be difficult, so please experiment extensively in your search for the best sound. In any
case, it is a great idea to use the Memory function on the Remote Control to compare settings and
to listen to the system for a few days before making any final adjustments.
M E M O R Y S E T T I N G S & P R E S E T S
The DALI MENTOR SUB Remote Control offers three user-defined memories, allowing you to
optimise the performance for (e.g.) surround (movie) and 2-channel stereo (music) playback
according to your desired settings: Press and hold the desired memory button (1, 2 or 3) on the
Remote Control for 3 seconds to store a user-defined preset. Briefly press 1, 2 or 3 on the Remote
to select any preset you have previously stored.
NOTE
When using two MENTOR SUBs, the best results
are normally achieved by positioning the two subs
relatively close to each other (1 – 2 meters).
