Power
This is the PREMIUM PR:O powered cabinet's on/off button. The Limiter/
Status LED lights up green to indicate the cab is powered up.

Gain
Use this knob to adjust the input gain to match the incoming signal's level.
Adjusting volume levels with the Gain knob:
The +4 dBu (center-notched) position is the factory default setting. It is
tuned to achieve the right balance of levels between the mid/ high unit and
subwoofer. If necessary, turn the Gain knob to adjust the balance of levels
between the mid/ high unit and subwoofer(s) to suit the incoming line
signals.

Mic/Line Selector
When connecting a microphone, you can optimize the input's gain level by
setting this switch to Mic. This setting provides a 30 dB boost.
When connecting a line-level source such as a mixer, audio playback device,
or electronic musical instrument, set this switch to Line.

Input
Route the incoming audio signal into this electronically balanced,
combination XLR/ 6.3 mm (1/4") input (pin 1 = ground, 2 = +, 3 = -).

Limiter/Status LED
This dual-color LED serves as a status indicator for the PREMIUM PR:O
powered cabinet (green = power on, red = limit/error). The LED briefl y
fl ashes red to tell you the limiter is responding to signal peaks.
Caution! If the Status LED stays red during operation, the cabinet is being
overloaded. Turn down the signal level! If you are not routing a signal in
and the Status LED stays red, the system has detected a fault.

Auto Standby
PREMIUM PR:O mid/ high units have a power-saving function that can be
activated and deactivated. The power amp switches to standby mode when
the button is set to On and the unit does not receive a signal for about four
hours (consumption <0.5 watts). To power the PREMIUM PR:O cabinet
back up again, simply set its Power button to Off for fi ve seconds and then
back to On. Mid/ high units will remain up and running if you disable Auto
Standby by setting this button to Off .

Tone
The Tone knob adjusts the frequency response to suit the given application.
Setting the knob to the center position defeats the fi lter.
Turning the Tone knob counterclockwise towards Music
attenuates by up to -6 dB a broad midrange band with a center
Music
frequency of 2500 Hz, thereby taking the edge off the sound.
The overall volume is not aff ected.
Turning the Tone knob clockwise towards Speech activates a
80-to-200 Hz low-cut fi lter, which enhances clarity for speech
Speech
applications and reduces subsonic noise.
The X models (PR: O 10 XD, PR: O 12 XD, PR: O 15 XD) are also tuned to
minimize feedback and distortion at high volume levels.
●
8
Flat/Boost Selector
Setting this switch to Flat conjures the optimum linear
frequency response for live performances and for operation in
Flat
combination with subwoofers.
Setting this switch to Boost pumps up the bass. This boosts a
broad band of bass frequencies in the kick-drum range between
Boost
70 Hz and 80 Hz and extends the low-end response.
●

Thru
This passive parallel output routes the signal routed into the front-end
Input back out again (pin 1 = ground, 2 = +, 3 = -).

Mains
Use the factory-included power cord to connect this socket to a wall outlet.
