9.4. Channel indicators
Each of the 4 input channels has two indicators. The green SP (Signal Present) LED
indicates the presence of a signal at the input selected with the active input selector.
If this LED does not light up when an audio source is delivering a signal, make sure
that the equipment has been properly connected, that the source you want to hear is
selected - channel source selection switches -, and/or that the GAIN control is
correctly adjusted.
The red CLIP LED indicates a risk of saturating the channel if the recommended
signal level is exceeded. This indicator may light up sporadically without risk to the
equipment but should never remain on continuously.
The PAIR button LED indicator shows the device pairing status:
 The PAIR LED blinks: Pair mode enabled, the device is visible (from the mobile
device Bluetooth
®
adjustment settings) and ready to establish connection.
 The PAIR LED is on: A Bluetooth® connection already done. The device is
paired.
 The PAIR LED is off (but the eCOMPACT4BT device is on): CH1’s line input is
selected.
9.5. Talkover function
When the Talkover function is activated, the input signal selected for channel 4 has
priority over the main mix bus, i.e. when a signal is detected at the priority input
(signal level above threshold), the mix bus signal is attenuated at the MAIN OUT and
SUB OUT. ALT OUT is not affected.
9.6. Outputs
The eCOMPACT4BT has two independent outputs, with their own volume control:
MAIN OUT and ALT OUT. It also has a SUB-OUT sub-bass or auxiliary output, which
delivers a mono copy of the MAIN OUT signal.
The ALT OUT signal is taken from the mix bus before the Talkover function is
triggered, so there is no attenuation by the Talkover function. This output can be
used as a recording output – REC OUT – which may or may not include (using ALT
OUT SEND) the signal that triggers the Talkover function.
When manipulating the main output level of the mixing console, care must be taken
to ensure that the CLIP indicators of the connected power amplifiers are never
permanently lit, but at most at the rhythm of the lowest frequencies that reach them.
