ZXi60.4+1K 5-CHANNEL AMPLIFIERS
The 4 channel amps have the same features as the 2 channel models accept that there are 2 sets of
controls.
1 set for channels 1 & 2 and 1 set for channels 3 & 4.
In addition, the 4 channel models have a Mode switch. Switch to 2 channel if you only have 1 set of
RCA’s in CH 1/2 and the unit will automatically supply signal to channels 3/4. Select 4 channel if you
are providing RCA’s to channels 1/2 and 3/4.
The X-OVER slide switch selects the internal crossover functions:
-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting
simplifying daisy chaining of amplifiers.
-HP: Selects the built in HIGH PASS filter, variable from 10 Hz to 15kHz.
-FULL: Bypasses all crossovers for full frequency range operation.
-LP/BP: Selects the built in LOW PASS , variable from 30 Hz to 150Hz.
LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 6V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy
chain multiple amplifiers from one signal.
BASS EQ: Fixed 45Hz bass boost variable from 0dB to 10dB.
Note that the LOW PASS signal is MONO.
-In the LP/BP position, the HIGH PASS filter acts as a
subsonic filter.
-When the LP/BP mode is selected, a 0 to +10dB, at 45Hz,
BASS EQ is also switched in.

CH1/2 CH3/4
The ZXi60.4+1K has three sets of inputs:
Line inputs on RCA jacks for channel pairs 1&2, 3&4, and MONO channel 5. These inputs can be used in
various combinations, to suit the application, depending on the settings of the INPUT MODE switch, and
the X-OVER switches for channels 1&2, and channels 3&4, respectively.
INPUT MODE slide switch:
- In the CH2 position, ALL five amplifier inputs are selected from the CH1/CH2 RCA jacks. Channel 5
receives a mono mixed signal.
- In the 4CH position, channel pair 1&2 receive input signal from RCA jacks CH1 and CH2, and channel
pair 3&4 receive input signal from RCA jacks CH3 and CH4. A mono mixed signal from these four RCA
jacks are also fed to channel 5.
- When 5CH DISCRETE is selected, each channel receives an input signal from its respective input RCA
jack. Channel 5 has two jacks on its LINE INPUT, which are summed together.
CH1/2 X-OVER slide switch:
- HI: Selects the HIGH PASS filter, variable from 10Hz to 15KHz.
- FULL: Sets this pair to full range operation.
CH3/4 X-OVER slide switch:
- HI: Selects the HIGH PASS filter, variable from 10Hz to 15KHz.
- FULL: Sets this pair to full range operation.
-LP/BP: Selects the built in LOW PASS , variable from 30 Hz to 150Hz.
CH 5:
- The channel 5 functions were chosen to be very specific to mono bass operation, and not switchable:
- The LOW PASS filter has a variable range from 30 Hz to 150 Hz.
- The BASS EQ gives a bass boost, 0 to +10 dB, at 45 Hz.
