Installation & Operation

Connecting the DC520 to your audio
system is simple. Using standard RCA to
RCA audio interconnect cords, connect the
left and right 

jacks on the rear

panel to the 

jacks of your

receiver or preamplifier. Connect the

jacks on the DC520 to the 

jacks of your receiver or

pre-amp. 

Connect the power to a non-switched AC
wall output, or to the accessory outlet on
the rear of another audio device in your
system and you are ready to go!

NOTE: When using the accessory outlet on
another product to power the DC520 make
certain that it has the ability to power a
device that draws at least 14 watts of
current in addition to the requirements of
other devices that may be plugged into the 

accessory outlets. If you use a “switched”
outlet it is important to remember that the
host product must be turned on in order
for the DC520 to operate.

The DC520 may be used as a conventional
auto reverse audio cassette deck, playing
back tapes from either transport.

1. Check the tape for excessive slack before
use. If necessary, take up the slack by
inserting a pencil into one of the cassette
hubs and rotate the pencil to take up the
slack.

button for the

transport you wish to use.

facing down.

corresponding to the labeling on the
cassette), or reverse

to play the

opposite side of the tape. In any case the
tape will run into the direction in which
the arrow of the pressed 

button

shows.

movement may be momentarily stopped
