Hfi100.2 2-Channel Amplifier Applications; Full Range Stereo / Mono - Hifonics HFi100.4 User Manual

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.
FULL RANGE
STEREO LINE INPUT
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 -.

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.
