AC line connection
A sticker on the rear of the unit indicates the nominal voltage setting for the unit as it left the Symetrix factory. If
this does not correspond to the voltage setting for your locale then do not attempt to apply power to the 6000.
Instead, return the unit to your local Symetrix distributor for modification.
The 6000 is shipped from the Symetrix factory with a detachable AC power cable (IEC standard) included.
Depending on the intended destination, the power plug is either the US type (intended for 117 VAC use), or the
Europlug type. If the power cable's plug is not right for your locale, then please contact your local Symetrix dis-
tributor for the proper cable.
Once you have determined that the 6000’s operating voltage matches that of your locale and you are ready to
begin, follow these steps:
Plug the socket end of the power cable into the recessed AC power receptacle on the back of the 6000.
Plug the other end of the power cable into a three-hole grounded outlet or power strip.

WARNING
The 6000 is intended to be electrically grounded. It has been provided with a three-wire grounding
plug - a plug that has a third (grounding) pin. This plug will fit only a grounded AC outlet. This is a safety feature. If
you are unable to insert the plug into the outlet, contact a licensed electrician to replace the outlet with a properly
grounded outlet. Do not defeat the purpose of the grounding plug!
Mounting in an equipment rack
The 6000 occupies one rack space (1U) in a standard equipment rack with a width of 19" (48.3 cm), a depth of
7.8” (19.8 cm), and a height of 1.75” (4.45 cm). Allow at least 4” (10.16 cm) behind the unit for the protrusion of
connectors. We recommend you take care not to mount the 6000 next to devices that emit large electromagnetic
fields, such as audio power amplifiers. To do so may comprise the noise performance of the 6000. The 6000 has
been designed to conform to mechanical guidelines as described in EIA Standard RS-310-C and IEC Recommen-
dation 297.
Analog audio input connections
The 6000’s audio input connections are via standard female XLR jacks located on the rear panel. For optimum
system performance we recommend that the 6000 be connected to balanced signal sources. If this is not practical
in your situation, then you may connect to unbalanced sources. The following diagram illustrates recommended
cable wiring practices.
