Electro-Voice ZxA1 Series Owner’s Manual

LIMIT
The LED brief blinking indicates the power amplifier is operated at its limits. Short-term
blinking is not critical because the integrated limiter keeps distortion under control. Constant
lighting of the LED indicates the sound is negatively affected. Reducing the output volume is
strongly recommended.
MASTER
Level control for adjusting the power amp’s overall amplification. The level control affects
the volume of the line input and microphone input. To prevent distortion and clipping of
pre-linked mixing consoles, the control should generally be set to a value between 0 dB and
+6 dB.
MIC
Level control for adjusting the microphone input level independent of the master level.
MIC IN
XLR input for low level signals like microphones. The MIC IN and LINE IN may both be used
at the same time as a 2-channel mixer.
WITH SUB/FULL RANGE
When depressed, activates a 100 Hz highpass for use with a subwoofer, or if the ZxA1 is
used as a floor monitor. A pen or paperclip is needed to depress the switch to WITH SUB
mode.
LINE IN
Electronically balanced input for the connection of high-level signal sources like mixing
consoles or signal processors. Connections can be established using 1/4-inch TRS or
XLR-type connectors.
MASTER OUT
Output connector to send the signal to another speaker or subwoofer. The output is the sum
of both the MIC IN and LINE IN.
POWER
AC switch for switching the ZxA1’s power ON or OFF. The LED lights after turning the
power ON. If the LED is not lit upon turning the power on, make sure the AC cord is
correctly connected and the outlet is properly working.
MAINS IN
AC connection is established via an IEC-connector. A 10 ft (3 m) long AC cord with fitting
IEC-plug is supplied. Locking IEC power cords may also be used.
