PA-20mkII & PA-150
TASCAM's PA-20mkII and PA-150 power amps
are designed to offer affordability and reliability
for installed or portable applications. The amps
have balanced and unbalanced inputs for
flexible integration into any system. Front
panel level controls make for easy adjustments
for audio levels. For increased power on mono
application, both amps can be bridged. The
PA-20mkII also offers a convenient headphone
jack on the front panel.

The PA-20mkII and PA-150 offer professional features
at an affordable price point, fitting a number of
applications:
Home Studio
The PA-20mkII offers suitable power for near field
monitors, or for driving consumer speakers when
testing different listening conditions. The addition of
the headphone jack allows for easy personal monitoring
at night, in apartments, or during overdubs.
The PA-150's increased power can drive more
demanding near-field monitors, mid-field monitors, or
small public address systems.
Installations • Kiosks
The PA-20mkII's compact size and light weight is ideal
for portable systems, or permanent installations.
Whether the task is multimedia kiosks or small
background music systems, the PA-20mkII offers
plenty of power without taking up a large mount of
space or making additional noise.
For more entertainment driven kiosks which are using
sound to attract people's attention, or for systems that
need to overcome more ambient noise, the PA-150 will
deliver the power needed without taking tremendous
energy drain, or creating excessive heat.
