Chapter 2: AM713 and MA703 Converters 7
AM713 Back Panel
Input Voltage Selector This red switch allows the unit to oper-
ate in either 110/115 VAC or 220/230/240 VAC environ-
ments. A fuse must also be changed for 220/230/240 VAC op-
eration. Units are shipped set and fused for 110/115 VAC.
Power Connector (IEC) and Fuse Tray The IEC power connec-
tor accepts standard IEC power cords. The fuse tray contains
both the active fuse and a spare fuse for 220/230/240 VAC op-
eration. For information on changing the fuse see “220, 230,
240 VAC Operation” on page 2.
Analog Inputs (female XLR) 24 balanced, analog inputs on
XLR connectors. Input sensitivity is set from the front panel.
Auxiliary Analog Inputs (female XLR) Two balanced analog in-
puts on XLR connectors. Input sensitivity is set from the front
panel.
AES/EBU Digital Input (female XLR) Stereo AES/EBU digital in-
put on one XLR connector. Functions in parallel with the aux-
iliary S/PDIF input and the two inputs should not be used si-
multaneously.
S/PDIF Digital Input (RCA) Stereo S/PDIF digital input on one
RCA connector. Functions in parallel with the auxiliary
AES/EBU input and the two inputs should not be used simul-
taneously.
AES Sync In (female XLR) Master clock input for the converter
when using AES as Sample Rate Source.
AES Sync Thru (male XLR) Outputs the same signal connected
to AES Sync In.
Word In (BNC) Master clock input for the converter when us-
ing Word Clock as Sample Rate Source.
Word Out (BNC) Outputs a Word clock signal synchronized to
the Sample Rate Source. In the presence of an external Word
clock input, this connector provides a regenerated version of
that input signal. Without an external sample rate source, this
connector outputs the internally generated clock signal.
MADI Out (BNC) Outputs the digital audio signal.
• 1–24: Analog inputs
