C. FCC COMPLIANCE STATEMENT

WARNING: Changes or modifications to this unit not
expressly_ approved by t_h,e party responsible for compli-

ance could void the user s authority to operate the equip­ment.

Note: This equipment has been tested and found to com­ply with the fimits for a Class B digital device, pursuant

to Part 15 of the FCC Rules. These limits are designed to
provide reasonable .protection against harmful interfer-

ence in a residential-installation. This equipment gener­ates, uses, and can radiate radio frequency energy and if
not installed and used in accordance with the instructions
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does

cause harmful interference to radio or television recep­tion, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of-the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and

receiver.
Connect the equipment into an outlet on a circuit

different from that to which the receiver is
connected.

Consult your dealer or an experienced radio~V
technician for help.

The user may find the following booklet prepared by the
Federal Communications Commission helpful:
"Television Interference Handbook"
This booklet is available from the U.S. Government
Printing Office, Washington DC 20402.
Stock No. 004-000-00450-7

WARNING: The use of non-shielded analog output
cables and non-shielded digital input’ cables if coax is
used for the digital input (fibre optic interconnect need

not be shielded) will invalidate the FCC Certification of
this device and may cause interference levels which

exceed the limits established by the FCC for this type of
device.

UNPACKING AND ASSEMBLY

1. Open the box and remove the top layer ofprotective

foam. The following items will now be visible:

1 SBP-32X processor
1 ACpower cord
1 Packet containing,~the Owners Reference and warranty

card

Note: If any of these items are not included please con-

tact your authorized dealer immediately for assistance.
Save all packing materials. If you must ship your
SBP-32X in the future rep.ack the unit in its original

packaging to prevent transit damage.

E. BASIC INSTALLATION
AND CONNECTIONS

Before you install the SBP-32X into your system we

recommend following these guidelines in choosing the

location. This will facilitate a clean, trouble-free installa­tion.

CAUTION: When making connections to this component
or any other, make sure ttie power amplifier is OF1~ and

the preamplifier is in the MUTE or STANDBY mode.

1. Although well shielded, the processor should not be

placed in close proximity to hum-sensitive components
(i.e. PREAMPS, TURNTABLES, TUNERS, etc.)

2. As with any high quality component, ensure that the
vent openings in the chassis are i~ree from obstruction,

allowing the processor to dissipate heat created by,!ts
highly regulated power supply and high bias class A"

output stage.

3. Run the male end of the AC cord from the processor
location to a nearby wall socket. This will be easier to

accomplish no, w, as the component itself is not in the
way. Do not plug the AC cord into the wall socket at this
time!

dNOTE: While the SBP-32X has superb regulation and

oes not require a dedicated AC circuit, we strongly

advise against any connections through extension cords
or multiple AC adaptors. High quality 15 amp grounded
AC strips are acceptable.

3

CAUTION: Do not remove or bypass the ground pin on
the end of the AC cord. This may cause RFI (radio fre-

quency interference) to be induced into your playback
system.

4. Connect the Digital Output from a Krell CD Turntable
or any digital source to the Digital Input on the back

paneI of your processor..Ygur SBP-32X will accommo­~late digital input from eitlaer the coaxial or fibre optic

outputs of any CD, DAT or Satellite broadcast source.
Note: Care should be taken in selecting the type of cable

used to link the digital source to your processor. If co­axial cable is to be used it should be non-capacitive and

have a bandwidth in excess of 10MHz to prevent drop­out errors.

Notei I.f a fibre optic cable is selected we strongly recom­mencl that it be a-high quality quartz fibre cable. An

additional benefit ot~ filSre optic cable is a reduction of

ground loop problems that often occur in audio systems.

5. Connect the appropriate OUTPUT of the SBP-32X to
the line level INPUTof your preamplifier’ The red
banded connector indicates the right channel and the
white indicates the left.

The SBP-32X is equipped with two output configura­tions: Single-ended via RCA connectors and Balanced

via XLR connectors. If your preamplifier has high level
balanced inputs we recommend the balanced outputs of
the processor be used. There are considerable sonic
benefits associated with balanced operation.

NOTE: both outputs can be used to simultaneously feed
two different systems.
