PHASE
The blend of the sub and speakers is best when they are in
phase with each other. The best way to adjust this is to sit in
the listening position and listen to the bass response on a
musical track as you make the adjustment. Pick a track that
has substantial bass. As you move the slider in the app, listen
for unwanted peaks and anomalies that sound unmusical.
Remember, the Deep
TM
subwoofer will sound best when the
bass it reproduces appears to come from the full-range
loudspeakers.
AUTO ON/OFF
This feature automatically turns the Deep
TM
subwoofer on
when signal is present and o when the signal is not detected
for a period of time. The default setting is auto on, which is
in a power-saving standby mode that continuously monitors
the inputs for any signals. The LED will be very dimly lit. When
a bass signal is detected through the RCA input, power is
automatically turned on and the LED will become bright.
If no bass signal is detected within a 15-minute period, the
subwoofer will return to standby mode. Sensitivity of the
auto-on function can be set from 1 - 10 mV. The correct
sensitivity depends on thepre-amp or AVR used. However, a
value between 3 and 6 is recommended. If AUTO ON/OFF is
deactivated, the DeepTM subwoofer will remain
on permanently.
PARAMETRIC EQUALIZER
The parametric equalizer gives you the ability to adjust the audio
output (within the Deep
TM
subwoofer range) to your preference.
The app lets you choose and adjust the center frequency,
bandwidth, and gain. One of the most common challenges with
a subwoofer is the natural resonance frequency of the room. The
parametric EQ will allow you to address this problem. To reduce
unpleasant resonance, identify the frequency causing it by using
a test disc with test tones in the bass frequency range. Searching
“audio test disc” on the internet will provide you with several
options. Start by playing the bass notes in sequence. When a
bass note sounds unnaturally loud, this is the room resonance
that you can reduce with the help of the equalizer. To do this, set
the
CENTRAL FREQUENCY
control to the frequency determined
by the test disc. Select a
“NARROW”
bandwidth and reduce the
GAIN
control until the bass note is reproduced with the same
apparent loudness as the other frequencies. To selectively boost
a particular frequency range, you should increase the bandwidth
slightly and then slowly adjust the
GAIN
, avoiding any unnatural
droning effects.
