9.2. Monitoring
The eCOMPACT4BT is equipped with an audio and visual monitoring system
through headphones and VU meter.
The PHONES OUT signal is the same as that sent to MAIN OUT and SUB OUT (main
mix bus signal).
You can select the signal to be displayed on the VU meter between the main mix bus
signal (present on MAIN OUT and SUB OUT) and the ALT OUT mix bus signal.
9.3. Channel gain and equalization
These controls allow you to adjust input sensitivity level and tone for each channel
individually.
After connecting the various audio inputs, the GAIN controls of each input should be
used to obtain an optimal signal strength and maximum signal-to-noise ratio, so that
they can be used properly as sound sources in the installation. To do this, try to
maximize the volume controls of the audio players before adjusting the gain on the
eCOMPACT4BT. Use the level indicators on the front of the unit (VU meters) for
correct gain adjustment, ensuring that signal peaks are normally in the area near
0 dB (orange area in VU meters) and very exceptionally above it ("red" area,
saturation or clipping).
GAIN controls provide a ±30 dB adjustment range.
The 3-band tone controls (treble, midrange and bass) provide a ±30 dB range. Be
careful not to overload the speakers.
