SP-20AB MANUAL
The SP-20AB’s compact size and 20 watts per
channel make it ideal for modu lar use in large
commercial installations with multiple small
speakers. Its power capacity is also just right
for driving the small near fi eld monitors used
in most recording studios as a comparison
with the main control room monitors - it can
power them without overpowering them.
The SP-20AB’s output is available through
either of two connectors: standard banana
jack binding posts for speakers, or through
a male XLR connector. The Satellite/Remote
XLR output allows the unit to become a
headphone driver, linking any number of
‘Furman HR-2 Headphone Remote Stations
together via standard microphone cables.
Each HR-2 station conveniently clips to a
mic stand and provides individ ual volume
controls for two sets of headphones. When
used for overdubbing or rehearsal, this setup
provides more than adequate loudness in
all headphones (even older high-impedance
models), and allows each musician to set his
or her own comfortable volume level. When
the overdubbing is complete and the musi-
cians remove their headphones, the SP-20AB
can also power the tape playback speakers
through the banana jacks, as selected by
pressing the SPEAKERS but ton on the front
panel. An additional headset may be plugged
directly into the SP-20AB’s front panel. A
volume control is provided for it.
The SP-20AB has a convenient input level
control on the left side of the front panel. A
pair of yellow LED’s - one for each channel
- light up whenever signal is present (threshold
-30 dBu). Another pair of red LED’s show an
overload con dition in either channel.

microphone cables. The HR-2 comes with
snap-on, snap-off mike stand clamp.
