E - Power Supply Input Socket - Plug the Power Supply
Umbilical Cord from the Power Supply into this socket. Simply
rotate the plug until you feel a connection being made with
the socket.The plug will then insert easily into the socket when
pushing the connection together. Screw on the locking ring
allowing it to “click” to secure the connection (see figure 7)
N o t e : Do not attempt to unscrew the Power Supply Umbilical Cord from the Power Supply.

Sonic Frontiers enhanced implementation of the I

S bus.

S • e eliminates the necessity of jitter inducing clock
encode and recovery circuitry since independent and direct
connection of audio data and system clock information is
achieved.
Utilizing the mil-spec 13W3 “D-sub” miniature connector
system, separate dedicated clock, audio data and control
signals are conveyed from the digital source to the Processor
3 via discrete wideband low VSWR multiple coaxial and
balanced interconnections. Ultra high performance Motorola
PECL technology is utilized, providing high speed for mini-
mum noise induced jitter (1nS speeds). The enhanced fea-
tures of this interface standard allow conveyance of status
bit flag information, automatically determining Master/Slave
clock source relationships and clock frequency division
ratios for optimum system performance.

S • e compatible inputs & outputs.
G - OPT-ST Optical Input (Glass Fibre) - This input will
accept a digital connection from a digital source’s Glass
Fibre Optical digital output.
H - OPT-TOS Toslink Optical Input (Plastic Fibre) - This
input will accept a digital connection from a digital source’s
Toslink (Plastic Fibre) Optical digital output.
I - AES/EBU Digital Input - This input will accept a digital
signal from a digital source’s AES/EBU XLR digital output. A
110 ohm balanced cable terminated with XLR plugs should
be used for this connection. NOTE: The XLR jack pin connec-
tors for the Processor 3 are configured as follows: Pin #1:
Ground, Pin #2: Positive (+) Polarity, Pin #3: Negative (–)
Polarity. See Figure 6.
J - COAX-BNC Digital Input - This input will accept a digi-
tal connection from a digital source’s BNC - Coaxial digital
output. The BNC - Coaxial cable impedance should be 75
ohms.
K - COAX-RCA Digital Input - This input will accept a digi-
tal connection from a digital source’s RCA - S/PDIF -
Coaxial digital output. The RCA - S/PDIF - Coaxial cable
impedance should be 75 ohms.
L - COAX-RCA Digital Output - This connector will output
a digital signal in S/PDIF format to an auxiliary processing
device. The S/PDIF Coaxial cable impedance should be
75 ohms.
M , O-COAX-RCA SE Analog Output (Right & Left) - If the
balanced outputs are not applicable for use, the RCA single-
ended (unbalanced) audio outputs should be used when con-
necting the Processor 3 to the RCA single-ended audio inputs
of a line level preamplifier, control amplifier, integrated
amplifier or receiver. (Left channel output of the Processor 3
connects to the left channel input of control unit and right
channel output of the Processor to the right channel input of
control unit.)
N , P- XLR Balanced Analog Output (Right & Left) -
These are balanced audio outputs and should be used
when connecting the Processor 3 to the balanced audio
inputs of a line level preamplifier, control amplifier, integrat-
ed amplifier or receiver, if these units are so equipped. (Left
channel output of the Processor 3 connects to the left chan-
nel input of control unit and right channel output of the
Processor 3 to the right channel input of control unit.) NOTE:
The XLR jack pin connectors for the Processor 3 are config-
ured as follows: Pin #1: Ground, Pin #2: Positive (+)
Polarity, Pin #3: Negative (–) Polarity. See Figure 6.
Q - Power Supply LED - This green LED lights when the
Power Supply is plugged in and switched on.
R - Power Switch - In the “O N” position, this switch turns the
Power Supply on. In the “O F F ” position, the Power Supply and
Processor are off.
Note: Be sure the Power Supply Umbilical Cord (T) that is attached to the Power Supply
chassis is plugged into the Processor chassis and the AC power cord is plugged
in at both ends before the Power Switch (R) is turned on. Failure to do this may
cause damage to the Processor.
S - Detachable AC Power Cord Socket - Plug the Power
Supplies' AC Power Cord into this socket (see Figure 8). The
Processor 3 is factory set for the correct operating voltage for
the area in which it is sold (see rear of power supply for volt-
age setting). If a different operating voltage is required, please
contact an authorized Sonic Frontiers dealer, distributor or the
factory directly.
T - Power Supply Umbilical Cord - This Umbilical Cord
exits the Power Supply to plug into the Power Supply Input
Socket (E) on the Main chassis (see Figure 8 for connection).
N o t e : Do not attempt to unscrew the Power Supply Umbilical Cord from the Power Supply.
