CPB150 PowerBlock 150 Watt Stereo Guitar Amplifier
Congratulationsand thank you for choosing another Crate first in guitar amplification:
the Crate CPB150 PowerBlockTM 150 watt stereo guitar amplifier. The PowerBlock
packs a lot of power and patching options into an amazingly compact and light weight
package: 75 watts per channel @ 4 ohms, or 150 watts (mono) @ 8 ohms. With its
switch-mode power supply and Class D power section, the PowerBlock offers lots of
power, flexibility and tone, along with something no one thought you could get with such
a powerful performer: extreme portability! (The PowerBlock even comes with its own
padded travelling bag, which can be carried or slung on your shoulder, and even fits
neatly into the semi-open back design of Crate’s GT112SL speaker cabinet.)
The PowerBlock is housed in a light weight but virtually bullet proof anodized aluminum
chassis which also cools the amplifier when in use. The unit is protected against speaker
impedances below the recommended minimum, signal levels outside the proper operating
range for the unit, and extreme unbalanced stereo conditions. The front panel features three
bands of equalization, a gain and level control, and a headphone jack for private practice
sessions. The rear panel of the PowerBlock is loaded with speaker output jacks (for stereo
or mono use), a balanced XLR Line Out jack with level control, CD input jacks, and dual
purpose line in / effects loop jacks for adding external effects or for patching an external line
level signal into the PowerBlock. The PowerBlock also features speaker simulation circuitry
for enhanced sound at each of the audio outputs.
Designed by players and built for players, there’s really nothing else quite like your new
Crate PowerBlock! (In order to get the most from your new PowerBlock, please read
this user’s guide prior to its use.)
The Crate PowerBlock amplifier can drive up to four of our GT112SL cabinets, in stereo,
or drive a single Celestion speaker-loaded GT112SL to the hilt in mono mode.

control clockwise, overdrive distortion is
added to the sound.
Player’s note: One way to get a wide range of
sounds is to start with the PowerBlock’s Gain
control near fully clockwise and your guitar
turned way down. The resulting clean sound
“fattens up” as you bring up the volume on
your guitar.

: The PowerBlock is great for private
practice sessions - simply Connect a pair of
stereo headphones to this jack without con-
necting the amp to your speakers. The signals
at the Speaker Output jacks and the Line Out
and Effects Send jacks jacks (#9, 12, and 14,
rear panel) are not interrupted when head-
phones are used. (The signal at the head-
phones jack is enhanced by the speaker sim-
ulator circuitry for superior sound.)

frequency output of the amplifier.

cool blue when the amplifier is on.

frequency output of the amplifier.

Using the Effects Loop Jack:
The Effects Loop Snd/Rtn jack allows for virtually noise free connection of
external effects. You will need a stereo-to-dual-mono 1/4” adapter as
described in the illustrations below. This T/R/S jack is wired as follows: tip
= return, ring = send, sleeve = ground.
