Tweeter Output Level
The GTC04 is a very efficient
tweeter. If there is a need to
lower the tweeter output level,
a pair of 4 ohm / 5 watt resistors
can be connected in series with
the GTC04 as shown in Figure 3.
To avoid short circuits, make
sure that heat-shrink tubing or
electrical tape is used to cover all
exposed wiring.
The in-line crossover acts as a
high-pass filter as well as a pro-
tection device that keeps the
tweeter from being over-exerted
by low frequencies that it was not
designed to reproduce. Under
normal circumstances this
crossover should not be bypassed
or removed for any reason.
Bypass the installed capacitor
only when using an outboard
active crossover or a custom-
built passive crossover set above
5kHz.
