DM714 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.
AES/EBU Digital Inputs (female XLR) 12 AES/EBU stereo in-
puts.
Parallel AES/EBU Digital Inputs (female DB25) Three 8-chan-
nel digital connectors function in parallel with XLR digital in-
puts, and should not be used simultaneously with the XLR in-
puts. See “DM714: Pinout for Female DB25 Connector” on
page 21 for pinout diagram.
Auxiliary Analog Inputs (female XLR) Two balanced analog in-
puts on XLR connectors. Input sensitivity is set from the front
panel.
Auxiliary AES/EBU Digital Input (female XLR) Stereo AES/EBU
digital input on one XLR connector. Functions in parallel with
the auxiliary S/PDIF input and the two inputs should not be
used simultaneously.
Auxiliary S/PDIF Digital Input (RCA) Stereo S/PDIF digital in-
put on one RCA connector. Functions in parallel with the aux-
iliary AES/EBU input and the two inputs should not be used si-
multaneously.
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.
