Control Functions - MTX TERMINATOR Series Manual

CONTROL FUNCTIONS

1. Gain Control - The gain control matches the
input sensitivity of the amplifier to the source
unit being used. The operating range is 200mv
to 6V.
2. RCA Inputs - The RCA inputs accept signal from
either low-level (RCA) or high-level (speaker)
inputs up to 6V. Source units need a minimum
200mV output for proper operation of the
amplifier.
3. Power / Protect LED - The LED illuminates Blue
when the amplifier is powered on and operating
normally. When the thermal protection circuit is
activated, the LED illuminates Red and the
output is muted. The LED will return to Blue
and the amplifier will resume normal operation
once it has cooled to a safe operating
temperature. The LED will briefly illuminate
Red if the short or over / under voltage
protection has been activated. The fault
condition must be corrected before the amplifier
will return to normal operating condition.
4. X-Over Mode and Frequency Control
(TN150.2 / TN300.4) - These controls are used to
adjust the frequencies played by the amplifier.
Use the switch to select Low Pass, Full Range,
or High Pass. In LP or HP mode, the crossover
frequency is variable between 40Hz and 400Hz.
5. Input Configuration Switch (TN800.5) - This
switch is used to select 4-channel or 5-channel
mode based on the number of RCA outputs
from the source unit. Select 4-channel if the
source unit only has 4 RCA outputs, or
5-channel when connected to a source unit with
a dedicated subwoofer output.
6. External Bass Control (EBC) Port (TN250.1 /
TN500.1 / TN1000.1 / TN800.5) - This port
connects to the included MTX EBC to remotely
control the output level of the amplifier (sub
channel only on TN800.5).

7 . Bass Boost (TN250.1 / TN500.1 / TN800.5 /
TN1000.1) - This control is used to adjust the
Bass Boost level from 0 - 12dB. The Bass Boost
frequency is centered at 45Hz.
8. Subsonic Filter (TN250.1 / TN500.1 / TN1000.1)
This control is used to filter out unwanted low
frequencies from 10Hz (Off) to 55Hz. This is
used more often with vented subwoofer
enclosures, but some sealed enclosures can
benefit from this as well.
9. Low Pass X-Over Frequency Control (TN250.1 /
TN500.1 / TN800.5 / TN1000.1) - This control is
used to adjust the Low Pass crossover
frequency. The crossover frequency is variable
between 50Hz and 250Hz.
10. Speaker Terminals (+ / –) - These terminals are
connected directly to the speakers / subwoofers.
Terminator Amplifiers will accept up to a
10 AWG speaker cable.
11. Power Terminal (+12V) - This terminal is
connected with a power cable and inline fuse
or circuit breaker directly to the positive terminal
of the vehicle's battery. Terminator amplifiers will
accept up to a 4 AWG power cable.
12. Remote Terminal - This terminal is connected to
the "remote" wire from the source unit and
is used to turn the amplifier on when +12V is
applied.
13. Ground Terminal - This terminal is connected
with a short ground cable directly to the chassis
of the vehicle. The ground cable must be the
equivalent gauge as the power cable. Terminator
amplifiers will accept up to a 4 AWG ground
cable.
14. Phase Switch - This allows you to invert the
phase of the amplifier outputs. In phase (0°) is
default, but out of phase (180°) can improve
bass response in some applications.
