HFi100.2 2 CHANNEL AMPLIFIER APPLICATIONS

FULL RANGE STEREO

This is the most basic application for the HFi Series 2 channel amplifiers.

1. Interconnect cable checklist:

Connect the LINE INPUTS to the Radio/CD with good quality RCA cables.

2. Crossover Switch:

The X-OVER switch must be in the FULLposition.

3.Crossover frequency control checklist: N/A for full range operation.

4. MODE:

Should be in the STEREO position.

5. Line Level:

Refer to the section “Setting up systems after installation for best performance”

NOTE: Minimum final loudspeaker impedances:

4 & 2 Ohms stereo mode or 4-Ohms mono mode

This amplifier will not do 1 Ohm stereo or 2/1 Ohm mono operation.

MONO

This application illustrates the basic mono bridging method for all Hifonics amplifiers.

Interconnect cable checklist:

A MONO signal source is required, such as would be available from the mono sub bass output of an active crossover, whether stand alone, or built into a head unit or equalizer. Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the output stage of that source.

It is necessary to feed the SAME signal to both left and right inputs via a Y- adapter RCA cable. Connect the mono speaker positive terminal to the LEFT +, and its negative terminal to RIGHT -.
