1 [USB] indicator
Lights up when the power is turned on and the unit is
communicating with the computer or iOS device.
The indicator flashes continuously when the computer or
iOS device does not recognize the device.
2 [HI-Z] switch
Switches the input impedance (on
O/off N).
Turn this switch on when connecting high impedance
instruments, such as an electric guitar or electric bass,
directly to the [MIC/LINE 1] jack. When you turn this
switch on, use an unbalanced phone plug for connection
between the instruments and the [MIC/LINE 1] jack. If you
use a balanced phone plug, this device will not work
correctly.
NOTICE
Do not connect or disconnect any cables while turning on the
[HI-Z] switch. Doing so can damage the connected device
and/or the unit itself.
3 [MIC/LINE 1/2] jacks
For connection to a microphone or digital instrument.
This jack can be connected to both XLR-type and phone-
type (balanced/unbalanced) plugs. The XLR type is set to
the optimum level for microphone connection and phone
type is for line connection.
4 [PEAK] indicator
Lights up according to the input signal. Lights up when
the input signal is 3 dB below the clipping level.
5 [+48V] indicator
Lights up when the [+48V] switch (phantom power) is
turned on.
6 TRANSFORMER switch
Switches the transformer circuit of the [MIC/LINE 1/2] jack
on and off.
NOTE
The unit features one transformer of analog circuitry for each front
input channel, created by Rupert Neve Designs® specifically for
audio interface use.

CAUTION
To protect your speaker system, leave the monitor
speakers turned off when turning the [HI-Z] switch
on/off. It’s also a good idea to turn all output level
controls down to their minimum. Neglect of these
precautions may result in loud noise bursts that
may damage your equipment, your ears, or both.

Proper use of the HI-Z or LINE inputs
HI-Z
Guitar and bass with passive pickups (not battery
powered)
LINE
• Effect device, preamp, direct box
• Guitar and bass with active pickups (battery powered)
• Digital instruments, such as synthesizer
Setting optimum recording levels
Adjust the gain knobs so that the [PEAK] indicator flashes
briefly at the loudest input volume.
Use of the TRANSFORMER switch
ON (lit)
Passing the input signal through the transformer circuit
results in sound with natural compression and saturation.
OFF (unlit)
This setting results in a well-balanced sound that is faithful
to the original, which is the feature of D-PRE.
