LINE OUT –
This ¼” jack provides an unbalanced signal that is derived after the power amp and output
transformer. This signal level is dependent upon the Preamp and Master Volume settings. This output jack
can be used for sending the Black Pearl 30’s® signal to another amplifier or recording device. The signal is
frequency compensated to emulate a similar tone coming through the amplifier’s speaker cabinet. It is ideal for
feeding a passive transformer isolated direct box for effective connection to a PA system, or for recording use.
EFFECTS LOOP –
This is a serial effects loop, meaning that the signal exits the send jack passes through
the attached processing device like a compressor or effect processor, and returns through the return jack.
There is a “normaling” switch built into the return jack that interrupts the “normal path” signal from the preamp
to allow the signal from the effects loop to enter the power amplifier. The send jack can be used as a preamp
out and the return jack can be used as a power amp in.
FOOTSWITCH JACK
– This ¼” jack is where the BP30’s single button foot switch is connected. A 20 foot
cable is attached to the heavy-duty steel footswitch. IMPORTANT: The front panel selector switch must be in
the FOOT SWITCH position for the footswitch to function.
FAN SWITCH –
Traditionally, Class A designs normally run hotter thus reducing power tube life. The Black
Pearl 30® offers a whisper quiet fan externally mounted on the bottom of the chassis. This fan reduces the
heat around the tubes and inside the chassis by approx 50 °F. A fan switch is provided for those who may
prefer to not use this feature.
IEC RECEPTACLE AND FUSE HOLDER
– The detachable power cord should be inserted here before the
cord is plugged into an AC power source. Within the bottom portion of this receptacle is a small drawer that holds
the mains power fuse. An extra fuse is included in this plastic housing. It may be necessary to use a small tool to
pry the small drawer open. Be sure to use the appropriately rated fuse for your AC mains voltage conditions.
WARNING:
• NEVER OPEN THIS FUSE HOLDER WITH THE POWER CORD PLUGGED IN.
• USE ONLY THE FUSE VALUE AS INDICATED IN THE VOLTAGE CHART.
• NEVER ATTEMPT TO DISABLE THE MAINS POWER FUSE.
LINE VOLTAGE SELECTOR SWITCH
– Changes the voltage of the AC power with which the amp will
operate. 115 volts is the standard in the USA and Canada. 230 volts is the standard for most of Europe and
South America. Consult the voltage chart if you plan to use this amp for a voltage other than how it was
shipped from the factory, so that the proper fuse can be inserted. The BP 30 is rated for operation from both 50
HZ and 60 HZ power sources.
SPEAKER CABINET (COMBO VERSION)
• The Black Pearl 30® cabinet is constructed from 9 ply and 13 ply birch plywood. The cabinetry construction
is precise and designed to enhance the rich rounded tone of the amplifier and the Eminence® Alnico Red
Fang™ loudspeaker.
• The open-back cabinet design further enriches the Black Pearl 30’s® classic tone.
GETTING STARTED
• The Black Pearl 30® ships with all tubes installed. There is no need to remove any packaging around the tubes.
• After un-boxing the amp verify that the AC input voltage selector switch matches the power in your area.
• Make sure you send in your warranty registration card.
• Read your owners manual. There is valuable information and safety tips in this manual and the knowledge
you learn here will translate into enjoyable quality tone for years to come.
