X-Four; Features And Operational Controls - ESX X-TWO Benutzerhandbuch

The LINE OUT RCA jacks provide a linear fullrange audiosignal to supply an additional amplifier.
1
The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit. All 4 LINE INPUTS must be connected.
2
If there is only one stereo signal with two jacks available, you must use two Y-connectors to splice the signal.
The LEVEL INPUT CH1/2 and CH3/4 controllers adjust the input sensitivity of the amplifier to align the audio signal of the head
3
unit for the regarding channel pair (Channel 1/2 or Channel 3/4). The input sensitivity is adjustable from 6 to 0.2 Volts.
The HIGH PASS CH1/2 and CH3/4 controllers adjust the cut-off point of the frequency range to below for the regarding channel
4
pair (Channel 1/2 or Channel 3/4). The cut-off frequency is continuously adjustable from 10 Hz to 150 Hz.
The HIGH PASS controller works in the LP/BP mode as subsonicfilter and eliminates the lower frequencies (Bandpass-Mode).
NOTE: If this controller is turned to a higher value than the lowpass controller, no sound is hearable.
The CH1/2 and CH3/4 X-OVER switch selects the required operation mode of the amplifier on the regarding channel pair (Channel
5
1/2 or Channel 3/4).
Position LP/BP: Lowpass mode (The higher frequencies will be eliminated. Adjustable by the lowpass controller.)
The HIGH PASS controller works in this operation mode as subsonicfilter and eliminates the lower frequencies (Bandpass-Mode).
NOTE: If this controller is turned to a higher value than the lowpass controller, no sound is hearable.
Position HP: Highpass mode (The higher frequencies will be eliminated. Adjustable by the highpass controller.)
Position FULL: Fullrange mode (The whole frequencies will be amplified).
The LOW PASS CH1/2 and CH3/4 controllers adjust the cut-off point of the frequency range to above for the regarding channel
6
pair (Channel 1/2 or Channel 3/4). The cut-off frequency is continuously adjustable from 30 Hz to 150 Hz.
The BASS BOOST CH1/2 and CH3/4 controllers adjust the bass boost enhancement continuously from 0dB to +12dB at
7
45 Hz for the regarding channel pair (Channel 1/2 or Channel 3/4).
