BLACK BEAUTY – GETTING STARTED
Remove the AC cable from the accessory pack and connect it from the amplifier to a standard wall outlet. Make sure that the "Gain"
and "Master Volume" controls are set to the minimum position (fully counter-clockwise). Locate the power switch on the right side of
the front of the unit and turn the amplifier on. Upon powering up, don't be surprised if you hear a small pop. This is absolutely normal
and will not cause damage to your speaker system.
(Eliminating this "power on transient" would require a component called a relay. SWR chose not to incorporate this type of component
due to the fact that relays degrade signal quality and often fail, causing the unit to have no output and requiring a trip to a local ser-
vice center. If you wish not to hear the pop upon power up, locate the "Speaker On/Off" switch on the rear panel and set it to "Off"
before you turn the unit on. Be sure to remember to set the switch back to "On" afterwards, or you may find yourself wondering why
you don't hear anything.)
Plug your instrument into the desired input jack (refer to "Front Panel Features" for greater detail). Turn your instrument's volume up
to at least 75% of maximum and slowly adjust the gain control. Once you begin to play your instrument and you see the red light
(marked "preamp clip") over the gain control illuminate, back off the gain a bit. Now turn up the "Master Volume" and you should hear
the sound of your instrument amplified through the Black Beauty. For more detailed information, please read the entire manual care-
fully so that you can fully realize the potential of the your new Black Beauty.
For those who wish to use an extension speaker cabinet with the Black Beauty, please skip ahead to "Extension Speaker Output
Section."
