Description

The PBK15BT™ is a two-way sound reinforcement system based on a heavy-duty 15" woofer and a 14Ti™ titanium
diaphragm dynamic compression driver mounted on a medium coverage horn. It’s sleek modern appearance coupled with
excellent performance offer an outstanding package.

The lightweight yet rugged injection-molded plastic enclosure with molded-in stand mount cup facilitates portable use for live
music or PA sound. The rounded profile cabinet has three handles for ease of portability. A black powder coated perforated
steel grille provides woofer protection and a professional appearance.

The PBK15BT speaker system power amplifier is a low-distortion reliable passive air-cooled unit providing 450W peak
available power for the system.

Cooling is provided via a large heat sink for low-noise and reliable operation under any conditions.

Line Input is via a female XLR with balanced input and two RCA phono jacks to the preamp/EQ electronics, and a level control.
Mic input is via a female XLR with balanced input, and a 1/4" phone jack. A Line Output has a male XLR and a 1/4" phone jack
connector. These outputs allow linking of additional speaker systems, or feed of the signal to a powered subwoofer, etc.

Additionally, a USB/SD/FM/BLUETOOTH input port is provided to allow playback of MP3 files via a USB thumb drive.

ApplicAtions

The Peavey PBK15
or musical playback.

A typical signal source for the line-level inputs of the Peavey PBK15BT would be a sound reinforcement mixing console (mixer)
or the output from a CD player, MP3 player or tape deck. A dynamic microphone can be connected to the Mic Input and used
as well.

BT has a variety of applications such as sound reinforcement, public address, side fill system, karaoke

VoltAGe selection process

CAUTION: Always disconnect AC power cord from unit, or AC power
source before attempting to change fuse/voltage selector position!

WARNING!: Before AC power is applied to this device,
always insure proper operating voltage selection is
engaged to match AC power source being used.

Fuse holder tray (2) may select 110-120V AC or 220-240V AC by
aligning the arrow on bottom right of the IEC jack assembly with
the fuse holder arrow of the proper voltage range. To change
voltage range selection, remove fuse tray and flip tray over 180
degrees and re-insert into fuse holder. The fuse tray can be
removed by inserting a small flat blade screw-driver near the top
center edge of the fuse tray, and gently lever the fuse tray out.
The fuse tray will push outward and be sticking out approximately
1/4", then grasp the tray and pull it out all the way.

The fuse should be changed to the correct amperage rating. For
an input power voltage range of from 110VAC to 120VAC, use a 3.15
amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which
conforms to the international fuse classification "T3.15A". For an
input power voltage range of from 220VAC to 240VAC, use a 2.0
amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which
conforms to the international fuse classification "T2.0A".

The IEC power cord that is correct for your locale can now be
plugged into the IEC receptacle (3), and the Power switch (1)
activated to turn on the powered PBK15BT speaker system.

ON-OFF SWITCH (1)

This rocker switch supplies AC power to the PBK15BT™ when
switched to the ON position. The ON position is with the top side
of the switch pushed “in" or nearly flush with the rear panel.

FUSE (2)

The unit is AC power line fuse protected from overloads
and fault conditions with a slow-blow 5 x 20mm 250V fuse.

This fuse is located within the base of the IEC power cord
connector (2), just below the IEC connector blades. If the fuse
fails, THE FUSE MUST BE REPLACED WITH THE SAME TYPE AND
VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO
PREVENT VOIDING THE WARRANTY!

The fuse in the Peavey PBK15BT can
delay type 5 x 20 mm size 250V rated fuse.

For 110-120VAC operation, a fuse rated at 3.15 amps and 250V should be used, which conforms to the
international fuse classification "T3.15A".

For 220-240VAC operation, a fuse rated at 2.0 amps and 250V should be used, which conforms to the
international fuse classification "T2.0A".

be replaced with a time-

If the unit continues to blow replacement fuses, do not keep replacing them, it should be taken to a qualified
service center for repair.

To replace the fuse, be sure to remove the IEC power cord from the IEC socket. The fuse holder tray is located
beneath the IEC socket cavity. Pry the fuse holder tray out with a small flat blade screwdriver placed under the
center of the top edge of the fuse tray, and gently lever the fuse tray out. The fuse is held in a clip in the fuse tray,
and should be removed and replaced with a fresh 5 X 20mm 250V type fuse of the appropriate current rating.

Then, once the fresh fuse has been put in place, re-insert the fuse tray into the IEC connector assembly, making
sure that the voltage range selection is correct (see above section) and make sure it is fully seated and flush
with the outside of the IEC connector assembly.

IEC POWER CORD CONNECTION (3)

This receptacle is for the IEC line cord (supplied) that provides AC power to the unit. It is very important that
you ensure the PBK15BT™ has the proper AC line voltage supplied. You can change the voltage for your
PBK15BT by following the instructions above under the section VOLTAGE SELECTION PROCESS.

Please read this guide carefully to ensure your personal safety as well as the safety of your equipment. Never
break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a
ground pin, a suitable grounding adapter should be used and the third wire should be grounded properly. To
prevent the risk of shock or fire hazard, always be sure that the mixer and all other associated equipment are
properly grounded.

POWER LED (4)

Illuminates green when the power switch is on and power is present

MIC INPUT (5)

The Mic level input is of the low impedance type. The jacks are a female XLR and a 1/4" phone connector. Gain
is much higher than the line level inputs.

THIS INPUT SHOULD NOT BE USED FOR LINE LEVEL SIGNAL INPUT, AS IT WILL OVERLOAD AND DISTORT,
DESPITE THE MASTER VOLUME CONTROL OR THE MIC GAIN CONTROL BEING TURNED DOWN !

LINE LEVEL INPUTS (6)

The line-level inputs are of the medium impedance type. The female XLR jack is a balanced type, and a pair of
RCA phono connectors is available. Note the RCA jacks do not denote stereo operation, the signal from both
jacks is summed together into one signal that is fed to the speakers.

LINE OUT jacks (7)

These jacks are intended for the use of linking multiple PBK15BT in a line or to provide a feed to a powered
subwoofer, or other electronics that needs to receive a full range version of the input signal. The connectors
available are a male XLR jack, and a 1 / 4" phone jack.

CLIP LED (8)

It turns Red when the power amp clips or overloads.

MIC GAIN (9)

Controls the gain for the microphone inputs.

LINE IN LEVEL (10)

Controls the gain or output level of the line level input signal.

MASTER VOLUME CONTROL (11)

It is used to directly set the system output level for a given set of input channel input signals.

TREBLE CONTROL (12)

The Treble control provides a boost or cut of higher frequency content, such as cymbals, so that the tonal
balance can be adjusted depending on the signal source. Do not use excessive boost when playing sound at
loud levels, as the boost is not needed then.

BASS CONTROL (13)

The Bass control provides a boost or cut of lower frequency content, such as bass guitar, so that the tonal
balance can be adjusted depending on the signal source. Do not use excessive boost when playing sound at
loud levels, as the boost is not needed then.

USB CONTROL PANEL (14)

Controls the playback of MP3 files through the USB port

DISPLAY (15)

Digital display for USB MP3 functions

USB PORT (16)

For connection of a USB thumb drive for MP3 file playback.

DO NOT PLUG A USB CABLE FROM A COMPUTER INTO THIS PORT!

The PBK15BT™ USB MP3 input, and/or the computer USB output can be damaged as a result.
