Krell Chorus 7200 XD
DESCRIPTION
7-Ch Power Amp with iBias Tech
Featuring the KRELL XD Upgrade
The “XD” upgrade for the Chorus/Duo/Solo amplifiers reduces the output impedance to less than half of its original value. This lower output impedance better damps unwanted speaker vibrational modes. Changing the output impedance also necessitated re-compensating each amplifier stage to achieve optimal critically damped transient response. This ensures that the amplifier accurately follows the dynamics of the input signal.
