Using the Controls
Power
This front panel button switches the AMP Two on or off. A multicolored LED indicates its power status.
To use the Auto On feature, leave this front panel switch in the on position.
Speaker Selector
The AMP Two has two pairs of speaker outputs. Press button A to activate the A outputs. Press button B to
activate the B outputs. Both A and B outputs may be used simultaneously, provided the combined impedance
does not fall below 2 ohms.
Note: Before pressing either of the speaker selector buttons, be sure the AMP Two's level controls are set at the minimum position.
Phones
You can connect headphones to the AMP Two using a standard
1
⁄4" stereo phone jack. To deactivate the
speakers while you listen through headphones, simply turn off the A and B speaker selector buttons.
Meter X0.1
This switch increases the sensitivity of the meters by a factor of ten, which is useful for monitoring the
AMP Two's output at low volume. In other words, the meters will display ten times the actual power output
when this feature is active. A red LED in this switch indicates activation.
Peak Limiter
The peak limiter modulates high frequencies at high volume, protecting your speakers from damage or
distortion. A red LED also indicates activation of this feature.
