Bridged, 4 ohms: 200 watts x 2 chan.
CEA-2006 Compliant Amplifier
Features C.L.E.A.N. Set-up with 10-step set-up procedure
w/ input/output clip detection and indicator LEDs
Pulse Width Modulated MOSFET power supply
LED power (blue) and protect (red) indicators
Stealth top mounted control panel
Soft start turn-on
4, 3 or 2 channel operation
Nickel-plated RCA level inputs
Nickel-plated captive C-clamp terminals
High level input capable with Auto Turn-On circuit (RFIF2SW required, sold separately. Up to TWO adapters needed for this amplifier.)
3-way protection circuitry (thermal, overload, and speaker short protection)
On-board differential inputs eliminates noise picked up by the signal cable
Integrated Transâ�?¢ana technology simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality
MESHA3 reduces MOSFET temperatures, lowers distortion, increases durability, and prolongs the output device life span
DSM (Discrete Surface Mounted Components) utilize 1% tight-tolerances improving efficiency of the circuit and lowers operating temperature and potential for noise - similar to circuit boards designed by aerospace manufacturers
