Connect preamp signal cables from the head unit to these terminals.
CROSSOVER FREQUENCY
Controls the lowpass crossover point for the speaker outputs.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45Hz.
REMOTE BASS LEVEL CONTROL (RBC)
This port is for connecting the remote subwoofer level control. This allows
up to 20dB of volume adjustment. This is not a bass boost, it controls the
level of the low pass signal.
NOTE: This control is not compatible with the Phoenix Gold LPL44 level
control.
SENS
Used to reach maximum amplier power with a wide variety of headunits.
SUBSONIC CROSSOVER FREQUENCY
Controls the highpass crossover point for the speaker outputs to eliminate
extreme low frequencies.
OUTPUT
Provides a full range signal for an additional amplier. There is no signal loss if
using this output.
+12V
This must be connected to the fused positive terminal (+12V) of the car’s
battery. The fuse must be located within 18 inches of the battery.
REMOTE
This must be connected to switched +12V, usually a trigger wire coming
from the head unit or ignition.
GROUND
This must be connected to the negative terminal of the car’s battery or
bolted to a clean, unpainted part of the chassis of the vehicle.
NOTE: Visible through the plexiglass cover, a single blue power LED is located in the lower corner of all Z ampliers.
Connect preamp signal cables from headunit to these inputs. The front
AND rear inputs must be used, if only the front input is used then the rear
speaker outputs will have no output signal.
CROSSOVER FREQUENCY
Controls the crossover point for the speaker outputs.
SENS
Used to reach maximum amplier power with a wide variety of headunits.
CONFIG
FLAT: Crossovers are turned o
HPF: High pass crossover is on
LPF: Low pass crossover is on
+12V
This must be connected to the fused positive terminal (+12V) of the car’s
battery. The fuse must be located within 18 inches of the battery.
REMOTE
This must be connected to switched +12V, usually a trigger wire coming
from the head unit or ignition.
REMOTE MONITORING DISPLAY (RMD)
Connect optional RMD Voltage Diplay to this port.
SPEAKER OUTPUTS
Used to connect the amplier to speakers. Z500.4 minimum impedance
is 4 ohms bridged or 2 ohms stereo. Use Right + and Left - to bridge the
channels.
GROUND
This must be connected to the negative terminal of the car’s battery or
bolted to a clean, unpainted part of the chassis of the vehicle.
NOTE: Visible through the plexiglass cover, a single blue power LED is located in the lower corner of all SD ampliers.
