Owner’s Enjoyment Manual

No Sound

1. Check “Power” and remote turn on for

proper  voltage. (Is power light on?)

2.Center the fader control.
3. Turn up “Input Gain” control.
4.Check ground connections.
5. Is the “Aux” button in the wrong

position?

Hiss

1. Turn down amp gains
2.Turn down amp gains
3. Turn down amp gains
4.Adjust source unit output

Distorting

1. Adjust equalization levels

Speakers

2.Adjust gain levels
3. Lower volume level of source unit

Whine

1. Check impedance of source grounds to

or Buzz amplifier grounds for resistance.

2.Change isolation selection of

grounding jumpers. See page 7, #13.

2kHz: 

  Our ears are most sensitive to the octave centered

at 2 KHz.  Reducing it can prevent ear fatigue while boosting
it will add immediacy, presence and “attack”.

8kHz:

  The 8Khz control is the sparkle in the musical

spectrum.  What is sometimes perceived as ear piercing treble
is actually much lower than this in the high midrange areas.
The tips of women’s vocals, snare drums, some synthesizer,
higher brass and woodwinds are in this area.

Para-BASS: 

 One equalization control to cover all your

various bass needs...we don’t think so.  The unique Para-BASS
control in the FOUR.1 is flexible enough to satisfy the bass
requirements of audiophiles or true “bassheads”.

Sweep:

  Pick a frequency between 40 and 80 Hz.  The

lowest of lows and the frequencies you feel more than hear
live in the 40Hz range.  If you want tighter, kick in the pants
bass, you will probably head more into the 80Hz range.  As
you change frequencies the Para-BASS control automatically
adjusts the bandwidth or “Q” to the optimum level.
