Amplifier Owner’s Manual
TI2 1000.4
4 CHANNEL POWER AMPLIFIER
FRONT AND REAR INPUTS
Connect preamp signal cables from headunit to these inputs. The front and rear inputs must be used, if only the front input is used then the rear speaker outputs will have no output signal.
HPF/LPF CROSSOVER FREQUENCY
Controls the crossover points for the speaker outputs.
SENS
Used to reach maximum amplifier power with a wide variety of headunits.
X-OVER CONFIG
FLAT: Crossovers are turned off
HPF: High pass crossover is on
LPF: Low pass crossover is on
LP/BP: Low and high pass crossovers are both on, creating a Bandpass (BP) filter for midbass/midrange drivers. If running a subwoofer the HPF now becomes a subsonic filter, to turn off the HPF/subsonic filter set it to 20Hz.
Note: The front HP and rear LP crossovers extend to 4kHz, so its possible to run a component speaker system fully active. The tweeters would be powered by the front channels and the midbasses by the rear channels. Be sure to check with your speaker’s manufacture for the correct tweeter and midbass crossover points to avoid speaker damage.
+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.
REMOTE
This must be connected to switched +12V, usually a trigger wire coming from the head unit or ignition.
GROUND
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.
REMOTE MONITORING DISPLAY (RMD)
Connect optional RMD Voltage Display to this port.
SPEAKER OUTPUTS
Used to connect the amplifier to speakers. Ti2 1000.4’s minimum impedance is 4 ohms bridged or 2 ohms stereo. Use the Left + and Right - to bridge the channels.
CLIP INDICATORS (located on top of the amplifier)
Lights when the amplifier reaches near maximum output. Under heavy use the clip indicators should be flashing during the peaks of the music. The clip indicator should not stay lit for long periods of time (more than 1 or 2 seconds), if this is the case you need to reduce system volume or the SENS of the amplifier.
