Z-3-120 and
Z-3-240 Series zonal acoustic amplifier
|
|
|
|
|
 |
|
Modern Z-3-120 and Z-3-240 zonal acoustic amplifiers are
designer for amplification installation. They are equipped
7-point graphic equalizer, adapted to cooperation with 100V and
70V loudspeaker set line of total impedance of 4Ω. WS amplifiers
can cooperate also with fire equipment and Warning Sonic Systems.
An anti-damage protecting system of the finishing stage are used in
case of: output short-circuit, overload and power factor
overheating.
The amplifier has:
 |
Microphone-line input with overpriority
blocking all other inputs |
|
|
Symmetrical microphone input I with Phantom
power supply to be turned on and voice priority blocking other
inputs – XLR socket. |
|
|
Symmetrical microphone input II with Phantom
power supply to be turned on – XLR socket. |
|
|
Input III switchable: symmetrical microphone/
symmetrical line – Jack socket |
|
|
Tape recorder input IV, playback – Cinch
socket |
|
|
Input V CD playback – Cinch socket |
|
|
Input for recording – Cinch socket |
|
|
INSERT output/input – Jack socket |
|
|
Loudspeaker line outputs ( 4Ω, 70V, 100V ) |
|
|
Zonal controllable outputs 3 x ( 0 - 120W
/240W ) |
|
|
Power supply 230V/50Hz and 24V DC
