Coda S5.5 Stereo Amplifier



The S5.5 is a high-bandwidth, pure Class A stereo amplifier. External control allows the S5.5 to be bridged into a high-power monoblock. Internal relay switching provides distortion-free selection of balanced or unbalanced inputs. Input switching and true-standby bias toggle are controllable either from the front panel or optional remote control.
