SPECIAL CONNECTIONS USING TWO
MODEL TA-16 AMPLIFIERS
NOTE: The following setups should only be made
with two TA-16 Amplifiers (or one TA-16 Ampli-
fier and one TA-27 Amplifier). Making these con-
nections between one TA-16 Amplifier and an
amplifier of another manufacturer may cause
damage to one or both amplifiers.

CROSS CONNECTION OF TWO
REVERBERATION UNITS
For greater versatility of special effects from
two instruments, the reverberation units of
amplifiers #1 and #2 can be cross connected as
shown below. Only the connections of the output
cables between the amplifiers and reverberation
units are changed. The reverberation input cable
connections remain unchanged. When instrument
AMPLIFIER #I
TWO AMPLIFIERS CONNECTED IN PARALLEL
By connecting an instrument to two TA-16 Am-
plifiers in parallel, as shown, you will obtain
an increased power output. This larger output
power will give you greater coverage of extra
large areas.

#1 is played (into amplifier #1), the undelayed
reverb signal will come out of the speakers of
amplifier #1 and the delayed signal will come
out of the speakers of amplifier #2. When
instrument #2 is played (into amplifier #2), the
undelayed reverb signal will come out of the
speakers of amplifier #2 and the delayed reverb
signal will come out of the speakers of am-
plifier #1.
