Resumen del manual
Note: Before pressing either of the speaker selector buttons, be sure the AMP One's level controls are set at the minimum position. Phones You can connect headphones to the AMP One 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 One'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. Power Meters These meters indicate the output level of your AMP One. When the AMP One is powered up, the meters will be softly lit, indicating standby mode. Once the unit's power supply is stabilized, its meters will brighten completely. Input Level Controls These knobs adjust the incoming signal level and thereby act as volume controls. We recommend that these be set to max and your signal source (receiver, CD player, preamplifier, etc.) be used to adjust the volume. Hooking up the Wires (Back Panel) Audio signals travel out of one component and into another. All of your connections should also go from out to in. 1 Input Jacks Connect the line out jacks from your signal source (receiver, CD player, preamplifier, etc.) to the input jacks on the AMP One. Note: "Line In" and "CD In" jacks cannot be used simultaneously. 2 Bridging Switch (refer to wiring diagram) In addition to providing 80 watts RMS per channel in the stereo mode, your AMP One can be used as a high power mono amplifier, providing over 200 watts RMS. This can be accomplished by sliding the bridging switch from the stereo position to the mono position. For mono applications, use only the right channel input. Similarly, use only the right channel input level control. Note: Be sure to observe the correct speaker connections for bridged applications. Because of the high power output in this mode, we recommend initially setting the right level control at "min", and then adjusting the volume to the desired level. 3 Speaker Terminals More than one pair of speakers can be used with the AMP One. We have provided two pairs of speaker outputs, labeled Spkr A (left & right), and Spkr B (left & right). The speaker terminals are color coded. Red posts indicate positive (+) terminals and black posts indicate negative (–) terminals. Be sure to connect the positive output terminals of your AMP One to the positive input terminals of your speakers and the negative output terminals of your AMP One to the negative input terminals of your speakers. Note: Refer to the wiring diagrams on the next page for proper connection of speaker cables. - Stereo Setup In this configuration, the bridging switch is off for stereo operation. Connect the line out jacks from a stereo preamplifier to the line in jacks of your AMP One. Next, connect your speakers to the terminals marked Spkr A (observing proper polarity: red for "+", and black for "-"). Connect a second pair of speakers to the terminals marked Spkr B. Select between the A and/or B speakers using the front panel speaker selector buttons.

Connect the line out from a preamplifier to the right line in of your AMP One. Connect your mono speaker to the terminals of your AMP One, following the example in the diagram opposite. Use the right level control on the front panel to adjust the volume.
