Bridged loudspeaker connections
The GTA amplifi er can also be bridged for a mono confi gura-
tion. This allows the amplifi er to be used for one or several
subwoofers or mid-range drivers. In this confi guration, the
amplifi er combines the right and left channel to a single-
channel output (mono output).
Note:
The amplifi er can add the right and left signal information
only if the right as well as the left RCA connection were
carried out.
Caution:
In a bridge circuit, the amplifi er load must be 4 ohm or
higher. A lower load leads to an overheating or switch-off
of the amplifi er and can cause permanent damages.
Adjusting the type and range of the
frequency crossovers
With the GTA 2 Special, the type of frequency crossover (i.e.
"Low Pass" or "Hi-Pass") and the desired entry frequency can
be adjusted. For example, if a pair of subwoofers is to be
connected, the low-pass settings shown are required (Fig.
3). The entry frequency is dependent upon the frequency
range of the loudspeakers (see recommended frequency
range of the loudspeakers).
High-Pass
At a setting of 80 Hz, the amplifi er has a frequency range of
80 Hz to 25,000 Hz.
Low-pass frequency control
This control is active if the switch is in the position "Low-Pass",
and allows for setting the desired entry frequency.
Example:
At a setting of 150 Hz, the amplifi er has a frequency range
of 10 Hz to 150 Hz.
Bass boost
The bass boost control is used to adjust the bass response
of the amplifi er.
The adjustment range is from 0 dB to +12 dB.
