KEY FEATURES & SPECIFICATIONS
MPA680us AMPLIFIER
(4x55W/2x150Wrms - MAX OUTPUT=680W)

The MPA680 amp brings multi-channel operation and flexibility to the entry level price points. Heavy on power and reliability, but including features for the most unique of installs, these amps really come through!

The MPA680 is a 4-channel design ideal for adding on 2 or 4 channels with tons of power in all modes but able to mate up with complementary subwoofer amplifiers for the ultimate satellite/subwoofer multi-channel system.

KEY FEATURES
Key features for this amplifier include:

  • RCA phono & terminal block style hi-level inputs.
  • Input sensitivity controls of 0.3 - 4.0 vrms for line level outputs or direct speaker level connections on the input.
  • Heavy aluminum heat sinks with extensive finage for maximum heat dissipation thus continuous operation under the hardest loads.
  • Load stability minimum of 2 ohms (non-bridged) offering incredible power output when driving parallel configurations.
  • Signal to Noise ratios >100dB to ensure clean signal amplification without background hiss or "grunge" on the audio signal.
  • "Passive" multi-mode capable allowing a derived 3-channel operation (2 high-pass satellites / 1 subwoofer) using outboard coils and capacitors.
  • Fixed and variable high-pass/low-pass filters with wide range frequency settings for maximum installation flexibility.
