9. Monaural input terminal [1, 2, 3, 4] (XLR-3-31 or equivalent)
Electronically balanced input terminal.
(Pin 1: Ground, Pin 2: Hot, Pin 3: Cold)
Use XLR-3-12C or equivalent for connection.
Input sensitivity (–50/–36/–10/+4 dB) and phantom power (+48 V) ON/OFF
settings can be performed by a PC using the D-2000 Setting software
supplied with the D-2008SP.
Notes
• Be sure to turn off the phantom power (+48 V) when using an unbalanced microphone or equipment
such as a CD player or effecter other than a microphone. As doing otherwise may cause damage to the
unit.
• To insert or remove a condenser microphone that requires external power source, turn down the fader of
the corresponding channel, turn off its channel and the phantom power (+48 V), then wait at least 1
minute before inserting or removing. As doing otherwise may cause damage or failure to this module
and microphone.
• Noise may be produced when or after the phantom power (+48 V) is turned on or off. Be sure to turn on
or off the phantom power (+48 V) after turning down the fader of the corresponding channel and turning
off the channel.
Also, never operate the fader nor turn on and off the channel for 1 minute after turning on or off the
phantom power (+48 V).
• Current consumption of the phantom power supply must be 5 mA or less per channel.
10. Ground lift switch
When the D-2008SP is connected to other equipment, a ground may
create a loop, potentially generating hum noise. In such cases, the ground
loop can be cut off by setting the DIP switch on the circuit board to the
LIFT position.
Note
When shifting the DIP switch, never touch other parts on the circuit board.
