5.3. BC-2522 DOUBLE LINE STEREO INPUT MODULE.
5.3.1. Functional description
The Double Line Stereo Input Module BC-2522 permits the connection of two stereo inputs
A and B. These lines are connected to (18) INPUT A (L) and (19) INPUT A (R) for the left and right
Line A channels and (21) INPUT B (L) and (22) INPUT B (R) for the left and rigth Line B channels,
selection is by switch (1) INPUT A/B. If the selector is at rest input A is active, when the selector
is depressed input B is selected.
The gain of the selected input is adjusted with potentiometer (3) GAIN.
It is possible to convert this signal to mono by activating switch (2) ST/MONO
Switch (4) HFF activates a radiofrequency filter. (100 Hz).
With the aim of avoiding saturation a led indicator (5) CLIP illuminates on reaching
maximum signal level. If required this signal can be monitored by activating Push-button (13) PFL
ON, to send it to the pre-listen bus. This status is confirmed by the illumination of led indicator
(14).
Potentiometer (8) BALANCE regulates the left/right channel output signal balance. This function is
activated when switch (9) BALANCE ON is activated.
The output signal can be directed to the following outputs whenever the operative channel
selector (15) CHANNEL ON is activated:
Master 1, adjusts the send level with fader (16) and pushing the switch (10) MASTER 1
Master 2, adjusts the send level with fader (16) and pushing the switch (11) MASTER 2
Telephone buses 1 and 2, adjust the send level with fader (16) and pushing the switch (12)
PHONE.
This signal can also be sent to the following auxiliary outputs:
Auxiliary 1, the send level is adjusted with potentiometer (6) AUX 1 if working with the Auxiliary 1
send programmed pre-fader or the send level is adjusted with fader (16) once the send level to
Auxiliary bus 1 is set with potentiometer (6) AUX 1 when working with the send to auxiliary 1
programmed as post-fader and whenever the channel operative selector (15) CHANNEL ON is
activated.
Auxiliary 2, the send level is adjusted with potentiometer (7) AUX 2 if working with the Auxiliary 2
send programmed pre-fader or the send level is adjusted with fader (16) once the send level to
Auxiliary bus 1 is set with potentiometer (7) AUX 2 when working with the send to auxiliary 1
programmed as post-fader and whenever the channel operative switch (15) CHANNEL ON is
activated.
The position of the programming bridges and their functions are described in Section 7 of
this manual.
