ADVANCED MANUAL / Bit One /
42
This section shows the settings of the output
levels of the Bit One channels as displayed
by the software. Following please note the
description of each of the points marked with
numbers in the image below.
9.11 OUTPUT LEVEL
When “Clip“ lights up, it indicates the
clipping regarding the output channel.
When this occurs, you will just have to
decrease the output level of the
corresponding channel or decrease the
equalization previously entered.
1
By acting on one of the sliders belongings
to the output channels, you can adjust the
output level (- 40 ÷ 0 dB) for each channel.
2
This area of the screen shows the output
level of each single channel (- 40 ÷ 0 dB),
compared to the slider position of the
output channels.
3
If you click on the “Mute” button, you can mute the
corresponding output channels. If you click again on
the “Mute” button, the mute function will be disabled.
4
If you click on the “Link” button, you can simultaneously
adjust all the Bit One output levels. If you click again on the
“Link” button, the function will be disabled.
5
By acting on the “Master Volume” function, you can
adjust the system general volume (-60 ÷ 0 dB).
6
By acting on the “Subwoofer Level” function, you can
act on the subwoofer output level adjustments
(-12 ÷ 0 dB), if the system features a subwoofer.

a) Adjust the amplifiers sensitivity level at the minimum (3-4V RMS).
b) Balance the emission level of the system channels by moving the cursors (2) paying attention to maintain a
mid level centred at around -20 dB. Turn the output volume to an acceptable listening volume level.
c) Set the desired output equalizations
(see section 9.11).
d) Insert a CD playing a highly dynamic track.
e) Select the “Link” function (5), move the cursor and increase the output channels level until one of the
“clipping” LEDs turns on (1); move the cursor back of at least 2-3 dB (check the value on one of the displays (3).
f) Increase the “Master Volume” (6) up to the maximum undistorted level taking it close to “0” dB.
g) In case the signal is highly distorted with the “Master Volume” at “0” dB, you will have to decrease the output
levels (2). If, on the contrary, no distortion occurs, you will have to increase the amplifiers’ sensitivity until the
first distortion symptoms show: by doing this, you will make the most of all the available power.
WARNING: the output level adjustment (2) affects the system signal / noise ratio (whistle / background hiss).
We recommend that you always set the Bit One output level at high level and the amplifiers’ sensitivity at low
level, so the amplifiers will be less affected by noises / background hisses.
Unfortunately, a too high output level makes the clipping LED’s turn on (1), especially if equalizations with high
gain are applied. Therefore we recommend that you proceed as follows:
Remark:
This procedure leads you to set the system at “zero dB undistorted”. This is not always the best solution,
since, if you listen to a track that has been registered at a lower level or with lower dynamics than the track used for
the setup, a loss in dynamics may happen. So a good compromise needs to be found, depending on the listener.
Note: if the installation includes a mono Subwoofer, the sensitivity
of its dedicated amplifier needs to be increased by +3 dB
compared to rest of the amplifiers (see the chart Amplifiers
sensivity).
This empirical method considers many aspects and will provide
an improved adjustment capability of the “Subwoofer Level”!
