Hum noise may be generated when external
equipment is connected to the unit. Connecting
this terminal to the functional ground terminal of
the external equipment may reduce the hum
noise.
Note
This terminal is not for protective earth.
8. Speaker output terminals (with a terminal cover)
[OUTPUTS (DA-250D), OUTPUTS 100V (DA-250DH)]
Connect speaker cables to these terminals.
9. BRIDGE ON/OFF switch (DA-250D only)
[BRIDGE, ON

Setting this switch to ON transmits the Channel 1
input signal to both channels 1 and 2. (PARALLEL
mode)
Note that output signal levels can be individually
adjusted with each channel's Input level control
(3).
Setting this switch to OFF (factory-preset)
transmits each channel's input signal to each
corresponding channel. (STEREO mode)
Note
Be sure to first turn off the Power switch (1)
when changing this switch setting.
11. Input terminals [INPUTS]
Electronically-balanced input terminals.
Each removable terminal block (3 pins) is
internally connected in parallel to the
corresponding XLR type connector.
• Removable terminal block (3 pins)
H: Hot, C: Cold, E: Earth
• XLR type male connector (XLR-3-31 equivalent)
Pin 1: Earth, Pin 2: Hot, Pin 3: Cold
If a straight plug hits the rack's rear cover or
wall behind the rack when it is used for
connection, use the L-shaped plug instead.
