DocumentDocumentIRIDIUM SERIES Mono Class A/B Amplifier GZIA 1.700 Owner´s manual (AWV2.0) Features · High-quality class A/B amplifier · 1 ohm stable · Variable high pass filter · Variable low pass filter · High-level input with auto-on function · Adjustable input sensitivity · Turn-on delay · Thermal protection · Short protection · Overload protection · Bass level remote control included IRIDIUM SERIES GROUND ZERO GZIA 1.700 General mounting instructions · As a precaution, it is recommended to disconnect the vehicles battery before mounting the amplifier. Note: For new vehicles, disconnecting the battery might cause various errors in your vehicle´s electric system that can be cleared only by authorized service partners of your vehicle´s manufacturer! Please ask your service partner first before disconnecting the battery! · The power supply wire (+12 V) has to be protected within max. 20 cm / 8" by a main fuse holder with a fuse value matching the recommendation for your amplifier Note: If there is more than one amplifier connected using this power wire, the main fuse value must be equal to the sum of the recommended fuses of all connected devices. However, make sure the diameter of your power wire will be enough for the required current! · If necessary, replace a defective fuse by a fuse with identical quality and value · Never drill holes to the vehicle´s gas tank, brake lines, to wirings or any other important vehicle parts! · Never pass wires over sharp edges or vehicle parts due avoid any kind of damage · Keep the wiring away from the antenna and electronic devices contributing to radio reception · Lay the power supply wiring always separated from speaker wiring to avoid disturbance · The amplifier contains a temperature protection circuit that turns the device off in case of overheating. After a certain cooling time, it will turn on automatically. To avoid heat build-up, enough air supply for cooling must be provided. Never cover the surface of the amplifier´s heatsink entirely · The amplifier should NEVER be mounted onto a vibrating part or surface such as a subwoofer enclosure. This might lead to malfunction due to loosened electrical parts inside the amplifier. · Some amplifiers offer a high-level input option, however if a pre-amplified output (RCA) is available (at the head unit), it is strongly recommended to make use of them.

Frequencies above the selected crossover point will be filtered (40 Hz to 4000 Hz) To setup the crossover for the required use of the amplifier FLAT HPF LPF (BP) entire frequency range will be reproduced only mid/high frequencies will be reproduced only low frequencies will be reproduced. The HPF is activated simultaneously resulting in a band pass filter To adjust the required crossover point. Frequencies below the selected crossover point will be filtered (5 Hz to 500 Hz) Controller to adjust the input sensitivity Input sockets to connect RCA wires Important note: High-level and RCA inputs should never be used simultaneously! This may cause serious damage to the amplifier Head units without RCA pre-amplifier output signal, can be connected using the high-level input to connect the speaker output of the head unit directly. If used, the amplifier turns on automatically (auto-on feature) The remote input of the power supply terminal remains unused Important note: High-level and RCA inputs should never be used simultaneously! This may cause serious damage to the amplifier POWER (green) ok (correct operation) PROTECT (red) error (protection mode) To connect the wired remote control To adjust the bass boost level ( 0 to +12 dB @ 45 Hz) IRIDIUM SERIES GROUND ZERO GZIA 1.700 Trouble shooting guide Symptoms No audible sound Device does not turn on No sound on one channel Device turns off at medium / high volume Status LED turned on red Check / Cause Does the POW LED turn to green?
