This section details the output levels of the H8 DSP channels as displayed by the software. Please note the
description of each one of the points marked with numbers in the image below.
By acting on one of the sliders belonging to the output channels, you can adjust the output level (-40 ÷ 0 dB)
for each channel. The sliders activate according to the output setup.
This area shows the output level of each single channel (-40 ÷ 0 dB), referred to the outputs slider position.
By pressing the “Mute” button, you can mute the corresponding output channels. By pressing the “Mute”
button again, the output will be activated.
By pressing the “Link” button, you can simultaneously adjust all the H8 DSP output levels.
By pressing the Link button again, the function will be disabled.
By pressing the “Solo” button the output channels, with the exception of the one already activated, will be
muted. By pressing the “Solo” button this function will be disabled.
By using the “Volume” slider, the general system volume can be adjusted (-60 ÷ 0 dB).
By using the “Sub Volume” slider, the Subwoofer output level can be adjusted(-12 ÷ 0 dB),
if the system features a Subwoofer.
WARNING: the output level adjustment as detailed in affects the system signal / noise ratio (whistle / background hiss).
We recommend that you always set the H8 DSP output level high and the amplifiers sensitivity low, so that
the amplifiers will be less affected by noises / background hisses.
Unfortunately, an excessive high output level may cause a on the processor outputs, especially if equalizations
with high gain are applied. We therefore recommend that you proceed as follows:
a- Set the amplifiers at the minimum sensitivity level (3-4 V RMS) if not yet done
(see 8.1.21).
b- Balance the emission level of the system channels by moving the sliders Making sure a mid level
centered at around -20 dB is maintained. Turn the output volume to an acceptable listening volume level.
Remark: if the system includes a mono Subwoofer, the sensitivity
of its dedicated amplifier needs to be increased by +3 dB
compared to the rest of the amplifiers (see the “Amplifiers
Sensitivity” chart). This empirical method takes many factors
into account and provides a better adjustment of the
“Sub Volume”.
