Product details
The original idea, refined
Epicenter PRO focuses on bass restoration for enthusiasts who need more control than a basic knob. Balanced inputs and a line driver help preserve signal quality, while a switchable PFM subsonic filter (24 Hz or Bypass) protects subs from unloaded ultra-low content.

Maximum line-level input 10 Vrms with 7 kΩ input impedance. Output impedance 150 Ω. THD 0.03%, SNR >105 dB, response 10 Hz–22 kHz ±1 dB. Current draw 300 mA with a recommended 1 A fuse. Chassis 8″L x 5.5″D x 1.2″H; product weight 1.7 lbs.
