4 – Connections
USB connection
Use the included USB cable to connect the unit to a computer as
shown in the illustration.
CAUTION
Some USB devices access the USB bus frequently. In order
to avoid audio signal dropouts, clicking and other noises,
we strongly recommend that you do not connect other USB
devices to the same bus that this unit is using. Connecting
USB keyboards and mice, however, to the same bus should
not be a problem.
Audio connections
Analog audio signals input into this device from mics, keyboards
and other audio equipment can be converted into digital
signals and transferred to the computer via USB. In addition, by
connecting speakers (through an amplifier if not powered)or
headphones to this unit, you can monitor audio signals that are
input to this unit and output from the computer.
CAUTION
Before connecting audio equipment, set the unit’s INPUT
1/2 and PHONES LEVEL knobs to their lowest values.
Failure to do so could cause sudden loud noises from
monitoring equipment, and this could damage the
equipment or harm hearing.
Microphones
Connect mics to the ANALOG (BALANCED) MIC IN 1/2 jacks on
the rear panel.
Follow the procedures below to turn phantom power on when
using a condenser mic that requires it.
Turning phantom power on for the ANALOG
(BALANCED) MIC IN 1 jack
Set the analog input selection button to mic for the Analog
1 channel on the MIXER page. Then, press the MIXER PANEL
button until the INPUT 1 +48V indicator lights.
Turning phantom power on for the ANALOG
(BALANCED) MIC IN 2 jack
Set the analog input selection button to mic for the Analog
2 channel on the MIXER page. Then, press the LINK LINE
button until the INPUT 2 +48V indicator lights.
CAUTION
• Turn phantom power on only when using a condenser
microphone that requires it.
• Turning phantom power on when a dynamic mic or other
mic that does not require it is connected could damage the
equipment.
• Do not connect or disconnect mics while phantom power is
on. Doing so could cause a loud noise and might damage
the equipment.
• Before turning phantom power on or off, set the PHONES
LEVEL knob and the master fader on the MIXER page to
their minimum values. Depending on the connected mics,
sudden loud noises from monitoring equipment could occur,
and this could damage the equipment or harm hearing.
• Supplying phantom power to some ribbon mics will break
them. If you are unsure, do not supply phantom power to a
ribbon mic.
• Turning this unit off resets the phantom power setting, so
phantom power will be off when the unit is turned on again.
Follow the procedures to turn phantom power on again if it
is necessary.
Digital connections with sound modules,
MD/CD players and other audio sources
Connect the digital inputs and outputs of these devices to the
DIGITAL (AES/EBU) IN/OUT jacks on the back of the unit .
NOTE
This unit can output AES/EBU and S/PDIF digital audio
signals.
Use the Mixer Panel MIXER page DIGITAL OUTPUTS FORMAT
buttons to set the output format.
CAUTION
To use a digital input, the Sample Clock Source setting must
be set to Automatic on the INTERFACE page of the Mixer
Panel. (This makes the connected device the clock master.)
If Sample Clock Source is set to Internal, signals will not
be able to be input through the DIGITAL (AES/EBU) IN
jack and the signal from the DIGITAL (AES/EBU) OUT
jack will be looped back within the unit unchanged as the
digital input. In this case, depending on the settings of the
computer application, the signal from the DIGITAL (AES/
EBU) OUT jack could loop and result in noise. An example
and countermeasure are described below.
Example
In a DAW application, this unit's digital input is assigned
to the input of a track and this unit's digital output is
assigned to the output. In this case, input monitoring of
that track will result in the following noise loop.
Track output w unit's digital output w unit's digital
input w track input w track output (beginning of loop)
Countermeasure
In order to prevent this loop, turn input monitoring off
in the DAW or set the input assignment for that track to
something other than this unit's digital input.
Analog connections with electronic instru-
ments and other audio equipment
Connect electronic instruments and other audio equipment to
the ANALOG (BALANCED) LINE IN 1/2 jacks on the back of the
unit .
Analog record players
The output of an analog record player cannot be connected
directly to this unit. To connect an analog record player to this
unit, a phono amp and equalizer must be connected between
them (or the output jacks of an audio amplifier that has phono
input jacks must be used).
Monitor speakers
Connect monitor speakers (powered speakers or an amplifier
and speaker system) to the ANALOG (BALANCED) OUTPUT L/R
jacks on the back of the unit.
Headphones
Connect headphones to the PHONES jack (standard stereo) on
the front of the unit.
