IZA 2120-LZ front panel
POWER switch – ON/OFF AC power.
Power LED – Solid blue LED indicates the unit is ON. Blinking blue LED indicates the unit is in standby mode.
INPUT SIGNAL LED – LED is green from –37 dBu to 11 dBu, LED goes red over 11 dBu. MASTER LEVEL set at 5.
OUTPUT LIMIT LED – LED is green from –46 dBFS to –2 dBFS, LED goes red over –2 dBFS, approximately 80 W/channel. For
each output, 120 watts is 0 dBFS.
AUX INPUT – 1/8" (3.5 mm) stereo line-level input connector. A cable insertion mutes INPUT A and INPUT B for priority override.
Pages can still be made from the PAGE INPUT. AUX INPUT does not have any gain adjustment, therefore, all gain adjustments must
be done from the external source device.
INPUT A/B Switch – Allows selection of rear line-input channels A or B.
TREBLE/BASS Controls – Allows tonal adjustments of both outputs simultaneously. These are 1st order shelving filters that provide
±6 dB adjustment at 7 kHz and above (TREBLE) and 100 Hz and below (BASS). They have a slope of approximately 6 dB/octave.
MASTER LEVEL Control – Controls the overall system volume for both the loudspeakers and the AUX OUTPUT when the AUX
OUTPUT DIP switch is set to VARIABLE. If the AUX OUTPUT DIP switch is set to FIXED, the AUX OUTPUT maintains maximum
level.
Note: When using a REMOTE volume connection, the front panel MASTER LEVEL control becomes disabled. See “Remote control
connections” on page 29 for more details.
