Decibel Eleven Split Personality Amp Switcher Class-A, all discrete, high impedance buffer -eliminates losses due to splitting and allows driving long cable runs without high frequency loss. Second output is transformer isolated and includes a ground lift switch to eliminate the noise and hum from ground loops High quality transformer -provides extremely flat frequency response even when driving lower impedance line inputs Second output includes a phase reversal switch -corrects any polarity mismatch between two amplifiers MIDI Control -allows remote access to 128 custom presets using MIDI program changes and/or direct switch control using MIDI continuous controller messages
