CONTROL FUNCTIONS
13. X-over mode and frequency Control (4-ch)
These controls allow control over the frequencies played for the rear channels.
There is an option for Low/BandPass, Full Range or High Pass. In HP mode, the frequency
range is from 15Hz to 500Hz. In LP mode, the frequency range can be switched from 50Hz
to 800Hz, or 250Hz to 4kHz. In the higher range, the LPF can be set at 4kHz for a midbass
while the front channels are also set at 4kHz for a tweeter resulting in a 2-way xover and
eliminating the need for a passive xover. Even with a set up like this, the midbass can still
be protected by the HPF which is not defeatable. It can be set anywhere in the 15Hz to
500Hz range creating a bandpass filter for the midbass by eliminating any damaging lower
frequencies in the subbass region.
14. Bass Boost Level switch (4-ch/mono)
This switch can boost bass level by 0dB, 6dB or 12dB. The boost frequency is
centered at 50Hz.
15. Input mode switch (4-ch)
This function is for switching the rear channels' signal path. When switched to 4CH,
all 4 RCAs inputs are required. When switched to 2CH, the rear channels get their signal
input from the front channels in parallel.
16. X-over mode and frequency Control (2-ch)
These controls allow control over the frequencies played for TX2.350 & TX2.500.
There is an option for Low Pass, Full Range or High Pass. In LP mode the frequency range is
from 50Hz to 200Hz, In HP mode the frequency range is from 15Hz to 200Hz.
17. Power Indicator
This LED will light up when amplifier works properly.
18. Protection Indicator
The red LED will light up or be flashing if there is a fault presented to the amplifier.
Please disconnect the amplifier and resolve the fault before reconnecting the amplifier.
