Output Mode: Turn an Encoder knob to select DUAL or BRIDGE
(Bridge Mono). You will be prompted to confirm your choice. Press
an Encoder knob to confirm your choice. DUAL is the default. The
Bridge indicator on the front panel will illuminate when the amplifier
is bridged.
Input Y: Turn an Encoder knob to select STEREO or Input Y. You will
be prompted to confirm your choice. Press an Encoder knob to confirm
your choice. When Input Y is enabled, Channel 1's input signal feeds
both channels. STEREO is the default.
Speaker Preset: A preset is a group of DSP and amplifier settings
for a particular speaker. Turn an Encoder to view presets 1 through
10. Press the Encoder to recall the preset. For more information on
presets, see Section 4.3.
In the example shown below,
• Preset 7 was last recalled (it’s not flashing).
• Preset 7 has been modified (indicated by “changed”).
• The Preset name is “Vertec VT4881 MF.”
• The Channel-1 label is “MF – 1&2.”
• The Channel-2 label is “MF – 3&4.”
Attenuator Link: Allows either attenuator (Encoder) to control
both channels. Push an Encoder knob to select Independent or
Linked. Once the attenuators are linked, any difference in channel
attenuation will be maintained.
Clip Limiter: Limits the output signal to prevent clipping. Press
an Encoder knob to select ON or OFF. ON is the default.
Peak Voltage Limiter: Limits the output voltage to an amount
that you set, either OFF or 0 to 200 volts. Press the Encoder to turn
on the Limiter. Once it’s on, turn the Encoder to set the voltage.
When done, press Menu/Exit, Next or Prev.
Average Power Limiter: Limits the output power to an amount
that you set, from 0 to 8000 watts. Press the Encoder to turn on the
Limiter. Once it’s on, turn the Encoder to set the power. When done,
press Menu/Exit, Next or Prev. Additional controls, such as
attack and release, are available through IQwic.
Pink Noise Generator: Adjust the noise level from 0 dB to -100
dB (off) in 0.5 dB steps by turning Encoder 1 or 2. The level can be
adjusted only when this menu option is visible. Moving to another
menu turns off the noise generator. The default setting is –100 dB.
Attenuator Limits: You can set the maximum attenuation from 0
dB to –100 dB. No confirmation is needed. This feature allows you to
set an upper limit on the attenuators. Once set, the attenuation cannot
be adjusted above this level.
NOTE: The attenuator setting must be below the attenuator limit that
you are trying to set. For example, if the attenuator is set at –3 dB,
you cannot set the attenuator limit below –3 dB unless you also
decrease the attenuator level.
CH2 Sensitivity: Sets the input sensitivity of Channel 2. Turn an
Encoder knob to change the input sensitivity.
Note: If you do not see the sensitivity you need, try changing the
Maximum Analog Input level in the Advanced Features Menu
(described later). This makes different sensitivities available.
