Monoblock Power Amplifier

Amplifier Owner’s Manual

TI2500.1 - TI1500.1

INPUT

Connect preamp signal cables from the head unit to these terminals.

OUTPUT

Provides a full range signal for an additional amplifier. There is no signal loss if using this output.

CROSSOVER FREQUENCY

Controls the lowpass crossover point for the speaker outputs.

REMOTE MONITORING DISPLAY (RMD)

Connect optional RMD Voltage Display to this port

LEVEL

Used to reach maximum amplifier power with a wide variety of headunits.

SUBSONIC CROSSOVER FREQUENCY

Controls the highpass crossover point for the speaker outputs to eliminate extreme low frequencies.

BASS BOOST

Variable bass boost from 0 to +18dB @ 45 Hz.

LOW PASS LEVEL CONTROL (LPL)

This port is for connecting the optional remote level control (LPL44). This allows up to 20dB of volume adjustment. This is not a bass boost, it controls the level of the low pass signal.

PEAK INDICATOR

Lights when the amplifier reaches near maximum output. Under normal operation the peak indicator should be flashing during the peaks of the music. Peak indicator should not stay lit for long periods of time (more than 2 or 3 seconds), if this is the case you need to reduce system volume or level of the amplifier.

PROTECT INDICATOR

Lights red if there is a problem with the audio system. For example, speaker wire is pinched/shorted together or the amplifier is running too low of an impedance.

12V+

This must be connected to the fused positive terminal (+12V) of the car’s battery. The fuse must be located within 18 inches of the battery.

SPEAKER OUTPUTS

Used to connect the amplifier to speakers. Minimum impedance is 1 ohm.

REMOTE

This must be connected to switched +12V, usually a trigger wire coming from the head unit or ignition.

GND

This must be connected to the negative terminal of the car’s battery or bolted to a clean, unpainted part of the chassis of the vehicle.
