Ecler WPmMIX-T - Manual

WPmMIX-T
FUNCTIONS DIAGRAM
1. Microphone input volume control.
2. Microphone input bass (100Hz) and treble (10KHz) tone adjustments
(
10dB).
3. Line input volume control.
4. Microphone input XLR connector (balanced signal). Sensitivity: -20/-40dBV.
5. Line input RCA connectors. Sensitivity: -10dBV (unbalanced signal).
Microphone and Line signals are mixed together according the relative levels
defined by their respective VOL controls. This mix is available at the unit’s
Euroblock connector output terminals (balanced signal, 0dBV line level).
Additionally, the Microphone signal can use the Talkover function to
automatically attenuate the Line signal once the Mic signal exceeds the
Talkover detection threshold (see the Configuration diagram for Talkover
activation details).
CONFIGURATION DIAGRAM
1. MICRO Sensitivity: -20 or -40dBV (default position) selection.
2. Talkover function (*): ON (jumper inserted, default position) / OFF (jumper
removed).
3. Phantom power for the MICRO input: ON (jumper inserted) / OFF (jumper
removed, default position.
To gain access to these configuration jumpers, the PCB at the back of the unit
must be removed pulling it out of its connectors and then inserted again after the
changes are done. This process must be done with the unit unpowered.
(*) Talkover attenuation, applied to Line input: 30dB.
Talkover hold time: 3 seconds.

(**) The WPmMIX-T needs an external power supply, able to deliver from 12 to 17VDC and 40mA per each
WPmMIX-T unit. The suggested standalone PSU is the Ecler WP-PSU, which can feed up to 20 WPmMIX-T units
(depending on voltage loses due to cable runs and sections).
General advice: as long as the WPmMIX-T has no magnetic shielding, it is strongly advisable to avoid installing it
near electromagnetic radiation sources and high voltage wirings.
