Harman Kardon CDR 26 Operation and maintenance manual

CDR 26 SPECIAL NOTICE
Under certain circumstances, the CDR 26 may operate differently than the
description in the owner’s manual.
In particular, the unit will not be able to make a digital recording from an
external source such as a CD player, DVD player or MiniDisc (MD) player
(as shown on page 20 of the owner’s manual) when that player blocks a
special electrical signal, called “Sub-Q,” from the digital output. This signal
contains some of the data needed to tell the CDR 26 that the original disc
has started playing, and without it the CDR 26 cannot begin a recording.
This is beyond our control, as some manufacturers design audio products this
way to prevent digital copies from being made. Should you find that a digital
recording cannot be made from an external playback source, you may always
use an analog connection to make the copy by using traditional RCA stereo
cables and pressing the Input Select Button on the front panel or remote control
until ANALOG appears in the Information Display.
This does not affect the CDR 26’s ability to make high-speed dubs using the
unit’s own internal playback deck, and in many cases you will not encounter this
problem at all, since it is related to the brand of playback deck being used.
