PortaBass Amplifier
In the world of high performance bass amps, Ampeg amplifiers stand alone. In true Ampeg tradition, the
PBC228 offers you more power, performance and tone than any other bass amplifier in its class. The outstand-
ing features which set your new amplifier apart from the competition are listed below.
MDT POWER AMP / SWITCH-MODE SUPPLY: Micro Dynamic Technology amplifier circuitry and a
switch-mode regulated power supply provide maximum power in a small lightweight package – the effi-
ciency of these designs eliminates the need for heavy heat sinks, transformers and filter capacitors
THREE BAND ROTARY EQ: Three bands of equalization and a selectable middle frequency provide
optimum tone control
TWO SEPARATE CHANNELS: Change instruments without swapping instrument cables or read-
justing amp controls
ULTRA LOW, ULTRA HIGH SWITCHES: Enhances flexibility and tone control
EFFECTS LOOP: Send and Return jacks are combined with an Effects Blend control for virtually
noise-free use of your favorite effects
TRANSFORMER BALANCED LINE OUTPUT: XLR jack with level control, ground lift, and a
pre/post-EQ switch – for patching into house consoles, mixing boards, or external power amplifiers
ULTRA-PORTABLE COMBO POWER: Two 8” neodymium speakers combined with the lightest,
strongest materials available add up to the biggest-sounding little combo imaginable
PROUDLY MADE IN THE U.S.A.
