Remote Control; Connection Of The Vca Control - Ecler AMPACK2-70 Manual De Instrucciones

4.3. Remote control

AMPACK provides VCA remote control terminal strips for the volume of each channel,
labelled as REMOTE CONTROL on its front panel.
The combined usage of the rotary potentiometers located at the front panel (9) and the
remote VCA (12) control determines the final value of the signal's attenuation for each input channel.
Therefore, a certain value can be fixed for the signal attenuation using the rotary so that the remote
control via VCA will not exceed this value and viceversa, that is, the two controls are connected in
series.

4.4. Connection of the VCA control

The signal remote attenuation level for each input channel can be set using 3 types of external
devices connected to REMOTE CONTROL ports on the front panel:
a) Using a remote potentiometer with nominal resistance between 10kΩ and 50kΩ.
b) Using a device that generates a control voltage from 0 to 10V DC.
c) Using remote relays/dry contacts.
NOTE: you can connect a maximum of 16 REMOTE CONTROL ports in parallel to the
same hardware control potentiometer. It is essential to assemble all grounds from
amplifiers these ports belong to.
Cables can be up to approximately 500 meters, using a minimum section of 0.5 mm
