nstallation
I
Because the DR-1 dissipates very little heat, ventilation is not an important consideration, allowing greater flexibility for custom or built-in installations. Of course, reasonable judgement must be exercised to see that
the DR-1 does not obstruct ventilation required by amplifiers or other
equipment in the system. The unit must be mounted horizontally.
All DR-1s sold in the United States are configured for operation on a
60Hz ac power line producing between 108 and 126 volts. Export
versions of the DR-1 will have the correct operating voltage and frequency clearly marked on the back panel of the unit, near the ac power
cord. In all cases, the actual line voltage should be within + 5/- 10% of
the nominal rated voltage.
Electromagnetic Interference (EMI)
Considerable care has been taken in the design of the DR-1 to minimize
it’s susceptibility to radio frequency interference and other forms of EMI.
Choice of materials, physical layout, grounding practice, and power
supply design have all been specified with a view to reducing the impact
of electromagnetic fields on the performance of this unit, and to assure
that it does not radiate fields that might interfere with the operation of
other units.
Care in installation can often avoid EMI induced problems. The following
practices should generally be observed in any application, and will be
especially important where EMI may be a problem.
Audio interconnect cables should be kept as short as possible (3 meters
or less), and shielded cable should be used (cable which has two center
conductors, and a separate external shield connected at only one end).
Physical location and cable "dress" can be an important factor in minimizing hum pickup. The installation should situate the DR-1 away from
the preamplifier and other sources. Power (ac mains) cords should be
dressed to remain at least 4" (100mm) away from audio signal cables,
and from coaxial digital cables.

CONNECTION
The outputs from the DR-1 are digital signals only. You must have a D/A
(digital to analog) converter in order to provide an analog signal that your
stereo system can use. The DR-1 comes standard with a coaxial (RCA)
output connector. Use a coaxial digital cable to connect this output to the
digital input of your D/A converter. If your DR-1 is equipped with the
Professional Output option, it also has available connectors for AT&T
glass fiber optic cable or balanced (XLR) transmission lines. The choice
will depend on the available inputs on your D/A converter as well as
personal preference.

The DR-1 has special features to assist you in making tape recordings
of your favorite cds. These features are provided solely to assist you in
making legal copies of cds for your own private use. They are not
intended to facilitate illegal copying of copyrighted material.
One particularly useful feature is peak search, which will locate the
loudest passage on a cd and play it continuously (from 2 seconds before
the peak to 2 seconds after), allowing you to set the recording levels on
your tape recorder. To initiate this process, press the button labeled
peak. The process can be concluded by pressing STOP, or o/c.
The DR-1 will also determine for you how many tracks will fit on each
side of a tape, and set up a program to play only those tracks. To use
this feature:
-- press STOP if the cd is playing;
-- press edit to activate edit mode (display shows "EDIT") - this
selects the "normal" edit mode.
-- two modes are available: EDIT (normal) and OPT(imal). EDIT
- will determine which tracks fit on each side of the tape and
will stop on the last track. Tracks will be recorded in the order
in which they appear on the CD. OPT - will calculate the
number and order in which the tracks should be recorded to
best utilize available recording time.
-- if desired, use the << and >> buttons to display OPT(imal), or
CANCEL, or EDIT (normal). With the desired mode displayed,
press EDIT to select. Selecting CANCEL will exit edit mode.
-- the display will now show "C90" which is the default setting.
