UNPACKING 1. Open the box and remove the top layer of foam. The following items will now be visible: 1 REFERENCE 64 D/A PrOcessor 1 REFERENCE 64 Power Supply 1 Power Coupler 1 AC power cord 1 AT&T.
ASSEMBLY ASSEMBLY INSTRUCTIONS 1. The processor is designed to sit directly on top of its companion Power Supply. There is a mechanical interlock built into the front feet of the processor and the chassis cover of the Power Supply. The units are secured together in the rear by the power coupler.
ASSEMBLY 5. Locate the Processor/ Power Supply coupler assembly. This assembly can only be installed in one direction. The wider portion of the assembly with the mal~ connectors goes into the female connectors inthe center of the Power Supply. The female connec- tors on the power coupler go into the Processor’s male connectors.
PLACEMENT PLACEMENT Before you install the REFERENCE 64 into your system, we recommend that you follow these guidelines in choosing the location. This will facilitate a clean, trouble-free installation. 1. Although well shielded, the Processor should not be placed in close proximity to hum-sensitive components (ioe.
AC POWER AC POWER CONSIDERATIONS NOTE: While the REFERENCE 64 has superb regulation and does not require a dedicated AC Circuit, we strongly advise against connections through extension cords or multiple AC adaptors. High quality 15 amp grounded AC strips are acceptable.
CONNECTIONS INPUT AND OUTPUT CONNECTIONS CAUTION: When making connections to this component or any other, make sure the power amplifier is OFF and the preamplifier is in the MUTE or STANDBY mode. 1. Connect the AC Mains cord to the back of the REFERENCE 64 Power Supply and plug the power cord into th AC Mains.
CONNECTIONS 2. Connect the REFERENCE 64 analog output to the line level input of your preamplifier. The REFERENCE 64 is equipped with two analog output configu- rations" Single-ended via RCA connectors and Balanced via XLR connectors.
CONNECTIONS 3. The Left and Right channel RCA outputs are labeled on the back panel. The balanced outputs are not labeled. The balanced connector closest to the Left RCA output is the left channel output and the connector closest to the RCA right output is the right balanced output.

CONNECTIONS - TAPE MONITOR INPUTS AND OUTPUTS 1 Digital only tape output: Intended for CD-R or DAT 2 Digital monitor inputs using auto selection system 1 AT&T normally active, priority over coax input 1 coax selected by default system The digital signal at the tape output is the active digital input signal selected.
CONNECTIONS DIGITAL SOURCE TO D/A CONVERTER INTERLINK CONSID- ERATIONS Care should be taken in selectihg the type of cable used to link the digital source to your Processor, We suggest the AT&T wide-band width fiber optic cable be used. The AT&T format has a bandwidth of approximately 50 MegaBit.
CONNECTIONS ’"’ ’" ,’ TIMESYNC TimeSync is a proprietary interlink system that enables a Krell CD transport and REFERENCE 64 to link and run on the CD transport clock. The TimeSync system can only be had on specific Krell transports.
CONNECTIONS The operation of the Processor utilizing the TimeSync feature requires that the data input be selected first and then the be selected. The TimeSync and the DATA TimeSync input input selected must be from the same source.
CONNECTIONS HOW TO CONNECT AT&T CABLES: a. Remove the plastic cover from the outside of the AT&T transmitter (located on Transport) and receiver (located on Pro- cessor). b. Locate the slot on the top of the AT&T receptacle. c. Locate the key on the top of the AT&T cable.
OPERATION INPUT SELECT SWITCHING The REFERENCE 64 has multiple digital inputs. Each input has its own input switch and direct path to the digital Processor.
OPERATION SOURCE AND MONITOR SELECTION The SOURCE button directs the signal from the Processor input selection section to the DAC and analog output stage. The source button must be depressed to listen to the selected input through the main audio system.
OPERATION OPERATING INSTRUCTIONS 1. Select an input with the Input switch. Notice the Signal LED will illuminate when the digital ~ource is turned on and has linked with the Processor. Once this link is complete, the Processor is ready to pass a signal.
OPERATION NOTE: While your REFERENCE 64 will perform beautifully from the moment you turn it on, it requires a minimum warm-up period of 8 hours before it begins to show its strongest sonic qualities.
QUESTIONS AND ANSWERS Q. My CD player has both fiber optic and coaxial outputs. Which one should I use? A. Given a choice, we prefer the’AT&T optical link due to its ability to completely isolate the grounds between the digital source component and the Processor.
QUESTIONS AND ANSWERS Q. I am not getting any sound through the Processor. What could be wrong? A. Most likely there has been a simple mistake in installation. Check all connections IN and OUT of the Processor. Is the digital source component powered? Check all power connections.
QUESTIONS AND ANSWERS Q. While listening to my REFERENCE 64 1 experience occasional periods of silence through my speakers. Is my Processor malfunc- tioning? A. Drop outs are caused by two primary reasons. First, drop outs can be caused by data corruption.
