2. Description of DuaFire
2.1 Front Panel
The front panel has the following connectors and controls from left to right:
Input 1:
the first input channel is provided as balanced XLR input (
MIC IN
) for microphones and
1/4"-input (
LINE IN
) for line level signals. You can only use one of the two input connectors at a
time. The input level is controlled by the
GAIN
knob with peak LED next to it. Above the gain
knob is the
+48V
phantom power switch with LED that needs to be enabled if you are using a
condenser microphone. For a dynamic microphone, phantom power does not have to be enabled.
Input 2:
the second input channel is provided with a 1/4" connector (
LINE / HI-Z IN
) that can be
used for line level signals or high impedance instrument signals (like a guitar). Next to it is the
GAIN
knob to control the input level. With the
HI-Z
switch, you can switch between line level and
instrument / guitar signals.
Headphone Out:
the
HEADPHONE
output with 1/4" connector and gain control is located on the
right side (directly under the
POWER
LED).
2.2 Rear Panel
The rear panel has the following connectors and controls from left to right:
Power Connector:
even though DuaFire is bus-powered, it might be needed to connect an external
power supply (e.g. when DuaFire is connected to a PC with a 4-pin FireWire port). The power
supply gets connected to the
DC IN
port.
FireWire port:
the
FIREWIRE
connector is used to connect DuaFire to the computer.
