Functional Instructions - Hifonics VXi2000D Owner's Manual

The LINE IN RCA jacks must be connected with the RCA output jacks of the headunit.
1
The optional BALANCED INPUT is unlike the regular RCA-cables insusceptible against interspersion and interferences of the
2
vehicle's electronics. You need therefor a Balanced-Line-Transmitter with a special cable, which can be connected between the
head unit and the amplifier. The Balance-Line-Transmitter is not included in delivery. Refer to the further information on page 29.
Never use the BALANCED INPUT and the RCA jacks LINE IN at the same time.
The LEVEL controller adjusts the input sensitivity of the amplifier, to adjust the audio signal of the headunit. The input sensitivity
3
is adjustable from 6 Volts (MIN) to 0.2 Volts (MAX).
The PHASE controller allows to adjust the phasing between 0° and 180°. Hence, you are able to adjust the subwoofer perfect
4
to the vehicle's acustics.
The EXTENDED BASS CONTROL controllers allow a extensive adjustment of the bass frequencies.
5
The SUB BOOST controller defines the bass bosst from 0 to 12dB.
With the FREQ RANGE controller you are able to adjust, on which frequency the bass boost (SUB BOOST) is effictive.
The range goes from 20 to 80 Hz.
With the Q-CONTROL controller defines the Q-Factor of the crossover continuously, so that the playback quality of the cut-off
frequency can be adjusted. Thereby you are able to adjust perfect transitions between the loudspeakers.
• WIDE equates a Q-Factor of Q 0,3 (arrow left below) = very wide frequency range.
• NARROW equates a Q-Factor of Q 1,0 (arrow right below) = very narrow frequency range.
• Q 0,5 / LINKWITZ-REILLY is the standard-setting, this means the arrow points up (12 o'clock position).
• Q 0,7 / BUTTERWORTH is located at the arrow position right (3 o'clock position)
The SUB SONIC controller (Subsonic filter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid
6
a mechanical and electical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz and depends on
the size of the subwoofer. Is this controller adjusted higher that the LP controller, no sound is hearable.
