Description

Arachnid Amplifiers are the next step in amplifier fundamentals. Monoblock models take every advantage afforded by Class D switching amplifier technology, a compromise of power and efficiency. Each monoblock can power a paralleled pair of 2-ohm subwoofers, or a single 1-ohm load. A bridged/strapped pair of Arachind monoblocks combine their 1-ohm strength to a 2-ohm load. Regardless of the configuration, Arachnid amplifiers pave the road of reliability and longevity you expect from Soundstream.

1-OHM MINIMUM IMPEDANCE STABILITY
An amplifiers impedance stability is its ability to continuously power speaker(s) of no less than the given impedance per channel, without the risk of damage. Subwoofers are available in a variety of voice coil configurations and impedances, so be sure yours will be no less than 1-ohm.

LOW LEVEL RCA INPUT & PRE-AMP OUTPUT
Connect the low level (pre-amp) audio output of the car stereo to the amplifier, using good quality twisted pair RCA interconnect cables. The amplifiers pre-amp output daisy-chains the audio signal to multiple amplifiers of complex audio systems.

ACTIVE 12DB/OCTAVE CROSSOVERS & PHASE SHIFT
Active crossovers built into an amplifier are the most efficient type of crossovers to use in car audio systems. Active crossovers protect speakers from damage by harmful frequencies, and preserve optimum performance.

MILITARY GRADE FR-4 PCB W/ MOSFET POWER SUPPLY
FR-4 circuit board substrate is a woven fiberglass cloth impregnated with an epoxy resin, providing good electrical insulation properties and heat resistance exceeding 260OF. MOSFET power supply is the stable & efficient conversion of a vehicles Direct Current (DC) power to Alternating Current (AC) power for speakers.

DASH MOUNT CONTROL
Dash mountable control is included with this amplifier can be mounted anywhere in the vehicle, but near the driver seat is recommended. The gain level of the Arachnid monoblock can be adjusted on-the-fly to accommodate various music styles & your listening preference.

DIRECT SHORT, THERMAL, & OVERLOAD PROTECTION
Conventional amplifier circuitry include a self-preservation mode, which temporarily shuts down the amplifier, protecting it from stress and risk of damage. Protection triggers include speaker output direct short, speaker impedance less than the amplifiers stability, or other unknown conditions causing the amplifier internal temperature to rise to unsafe levels.
