$199.00
Overview
The AudioControl EPICFOUR is a compact Class D 4-channel amplifier rated for 100 watts RMS x 4 at 4 ohms and 200 watts x 4 at 2 ohms (14.4 V), with 400 watts x 2 when bridged at 4 ohms. A variable high-pass filter, hex-screw terminals, and smart auto-reset protection support clean full-range or multi-channel installs. Pair it with EPIC monoblocks when you want matching AudioControl power for speakers and subs.
Product details
Four channels of Class D power
EPICFOUR uses a high-current Class D design that is 2 ohm stable. At 14.4 V AudioControl rates 100 W x 4 into 4 ohms, 200 W x 4 into 2 ohms, and 400 W x 2 bridged into 4 ohms. Frequency response is 10 Hz to 22 kHz, and signal-to-noise is 90.1 dBa referenced to 100 W at 4 ohms.
High-pass filter and solid terminals
A 12 dB/octave Linkwitz-Riley high-pass filter is adjustable from Off through 50 Hz to 500 Hz for speaker protection and system tuning. Line-level inputs accept 500 mV to 12 V RMS. Direct-wire hex-screw terminals take 4 AWG power and 8 AWG speaker wire.
Install footprint
The chassis measures 9.41 inches long by 6.1 inches wide by 2.01 inches high without connectors. An 80 amp fuse is recommended. Smart auto-reset protection covers over-current, under/over voltage, DC offset, and over-temperature. Note: unlike EPIC monoblocks, EPICFOUR does not include an ACR-E remote or Epicenter Link harness.
