TAPCO TH-15A Features
REAR PANEL DESCRIPTION
• The TH-15A is designed to operate with a
+4 dBu signal when the LEVEL control is at
the U (center) position.
• The TH-15A can accept up to a +20 dBu
signal by turning down the INPUT LEVEL
control accordingly.
• NEVER connect the output of an amplifier
directly to the input of the TH-15A. This
could damage the active input circuitry
of the loudspeaker.
4. OL Indicator
The OL (overload) indicator lights when
the amplifiers in the TH-15A are near the
clipping point. It is okay if the OL indicator
blinks occasionally, because this means that
the transient peaks are just reaching the
maximum output of the amplifiers and you
are getting the most from your TH-15As.
If the OL indicator is blinking frequently or
lighting continuously, turn down the LEVEL
control [3] on the TH15A or turn down the
signal at it source (e.g., the mixing console)
until the OL indicator blinks occasionally or
not at all.

This is where you connect your signal to
the loudspeaker and make adjustments to
the frequency response of the speaker to
match the loudspeaker’s location and your
room’s environment.
1. INPUT
This is a female XLR-type connector that
accepts a balanced mic or line-level signal
from a mixing console or other signal source.
. OUTPUT
This is a male XLR-type connector that
produces exactly the same signal that is
connected to the input jack. Use it to daisy-
chain several TH-15A’s together off the
same signal source.
3. LEVEL
The LEVEL control adjusts the overall
signal level at the input to the built-in power
amplifiers. It ranges from Off ( ) to MAX
(maximum gain), with unity gain at the
center position (12 o’clock).
