demanding requirements with regard to sound quality and
sound impression. This is achieved by the consistent use of
Carver low-range speakers or woofers. This new speaker

with a 0.5 V CD changer (old) or a 2.0 V CD changer (new) and
switch over the input accordingly.
A 6-CD changer is additionally available for the E85.
A radio with a cassette drive can no longer be ordered.
