AMPLIFIER GLOSSARY TECHNICAL AND FUNCTIONS
1. "Front" RCA audio input
Use high-quality Genius stereo RCA cables, connect the
signal from the audio player to the amplifier's RCA inputs.
2. "Front and Rear" Gain Level
Adjust the "pre-amplified" gain level of the amplifiers. The
minimum sensitivity level is 0.2V, while the maximum level
is 6V.
3. "Front and Rear" High Pass Crossover
Adjust the frequency setting of the High Pass Crossover. The
range of the adjustable frequency is 20Hz-400Hz press the
frequency multiplier switch x 10, example 20Hz x 10 =
200Hz - 400Hz x 10 = 4Khz. And select your desired
frequency. The lowest frequencies that are filtered in the
audio signal. (All the frequency below the setting will be
filtered). All audio signals above the set level will be up to
20Khz.
4. "Front and Rear" Low Pass Crossover
Adjust the frequency setting of the Low Pass Crossover. The
range of the adjustable frequency is 50Hz-500Hz press the
frequency multiplier switch x 10. Example 50Hz x 10 =
500Hz - 500Hz x 10 = 5KHz and select your desired frequen-
cy. The frequencies higher than the setting, are filtered in the
audio signal. (All the frequency above the setting will be
filtered). All audio signals below the set level will go to 20Hz.
5. "Front and Rear" Crossover Selector
Activate the "High Pass", "Band Pass Filter" or the Crossover
FLAT (Full).
6. Selector 2Ch - 4Ch
The 2CH position. Allows you to use the RCA input of CH1 -
CH2 (Front) to output stereo audio through the 4 channels of
the amplifier.
- 12 -
CAUTION:
enter the unit code player radio.
GKE-120.4D
The 4CH position. Allows you to use the RCA input CH1-CH2
(Front), CH3-CH4 (Rear) to output stereo audio through the 4
channels of the amplifier independently.
7. "Rear" RCA audio input
Use high-quality Genius stereo RCA cables, connect the signal
from the audio player to the amplifier's RCA inputs.
8. LED POWER indicator
When the amplifier is on and in operating condition, this LED will
light blue.
9. LED Protection Indicator
If the amplifier activates the protection mode, this LED will light
red.
10. Powering the Amplifier
The B (+) and GND (GND) power supplies use a 4 AWG gauge
while the remote uses a 12 AWG gauge input (the REM terminal
is used to remotely turn the amplifier on and off when a Voltage
12V)
11. Speaker Terminals
The loudspeaker terminals are nickel plated that allows the
connection of cables of maximum size 10 AWG for the power of
the horn. NOTE: The configuration of each channel must be
checked by qualified personnel.
12. Frequency Range Multiplier
Pressing the switch increases the crossover frequency of all
channels by factor 10. Example, if we set the frequency (Hz) to
180Hz, and press the multiplier switch to change the frequency
to 1800Khz.
This function is executable in both the HPF-LPF position.
13. Protection Fuses:
2 x 40amp fuses.
