TAPCO TH-15A Features
REAR PANEL DESCRIPTION
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.
2. 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).
• 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.
5. HIGH EQ
This control gives you up to 15 dB boost or cut
above 12 kHz, and it is also flat at the center position
(U). Use it to add sizzle to cymbals, and an overall
sense of transparency or edge to the keyboards,
vocals, guitar, and bacon frying. Turn it down a little to
reduce sibilance, or to hide tape hiss.
6. MID EQ
This is a midrange EQ control that provides 15 dB
of boost or cut centered at any frequency between
100 Hz and 8 kHz. The MID EQ circuit is flat (no boost
or cut) at the center position. This frequency range
includes most vocals (male at
the lower end of the range and
female at the upper end of the
range), and the fundamentals
and harmonics for many
instruments.
. MID FREQ
This knob ranges from 100 Hz
to 8 kHz and determines the
center frequency for the MID
EQ filter. This allows you to zero
in on the precise narrow band
of frequencies you want to
have affected by the MID EQ.
8. LOW EQ
This control gives you up to
15 dB of boost or cut below 80 Hz.
The circuit is flat (no boost or
cut) at the center position. This
frequency range represents
the punch in bass drums,
bass guitar, fat synth patches,
and some really serious male
singers.
9. DIRECT/EQ Switch
This switch allows you to bypass the EQ section.
When the switch is out (DIRECT), the EQ section is
bypassed and the EQ knobs have no effect on the
signal. When the switch is pushed in (EQ), the EQ
controls can be used to tailor the frequency response
of the TH-15As.
10. POWER Switch
Use this switch to turn the active loudspeakers on
and off. The indicating LED above the POWER switch
lights when the POWER switch is on and AC power
is available at the linecord socket. A second power
indicator is located on the front of the cabinet.
