Congratulations on your purchasing of a McLELLAND Mix-Lite USB Audio Interface.
Please take a few moments to read the entire manual, and be sure to retain this document for
future reference. Please read and observe all safety instructions detailed on each page.
INTRODUCTION
The McLELLAND Mix-Lite USB audio interface is designed as an audio interface between analog
and digital audio sources, recorders and a computer with USB 1.1 or 2.0 connection. It is suitable
for use on stage and in the sound recording studio as well as for home recording and multi-media
applications. Microphone signals, high-impedance instrument signals, analog line signals and
digital signals can be transmitted with superior sound quality to a computer where they can be
edited, mixed and published with corresponding production software. The audio interface is
compatible to PC and Mac and requires no setup thanks to its plug & play functionality.
The interface features two combo inputs for microphones and high-impedance music
instruments, an input for units with line level(e.g. CD players) as well as an input for digital audio
signals. For the analog inputs the amplification can be adjusted and for phantom-powered
microphones +48V phantom power can be switched on.
The audio signals coming from the computer and the preamplified analog input signals are
available at two 6.3mm jacks as well as at an adjustable 3.5mm headphones output. Additionally,
there is a digital output for the audio signals coming from the computer. The power supply for the
unit is made via the USB interface. Alternatively the supplied power unit or the 9V battery may be
used for an operation independent of the computer.
This product is allowed to be operated with 9V AC/DC, 150 mA and was designed for indoor use
only.

1. USB port:
Type B connector, for connecting a computer. The audio data, digitized in the interface, is sent
to your computer via this USB port. It also acts as power supply for the Mix-Lite.
2. Mix control:
Selects and fades the signal for the analog outputs of the audio interface:
• left position PREAMP: preamplified signal of the input sources.
• right position CPU: audio signal coming via the USB connection.
• center position MIX: both signal sources(PREAMP and CPU) can be heard.
3. Monitor output:
3.5mm jack for connecting stereo headphones.
4. Level control:
For adjusting both the monitor output volume and main output volume.
5. S/PDIF IN:
Coaxial input(RCA) for connecting a signal source with digital output and supported sampler
frequency.
6. RCA IN:
Stereo RCA line input for connecting a signal source with line level(e.g. CD player)
7. S/PDIF OUT:
Coaxial output(RCA) supplies a digital audio signal output.
8. Main output:
Analog outputs(6.3mm jacks), supply the preamplified sinal of the input sources and/or an
audio signal coming from the computer(depending on the position of the control MIX). A
monitor system or units with line level input such as mixer, recorders or amplifiers may be
connected here.
9. +48V phantom power switch:
On/off switch for +48V phantom power at the XLR inputs.
NOTE: When phantom power switched on, no microphones with unbalanced output
must be connected as these microphones may be damaged.
10.9V AC/DC power input:
For connecting the supplied power unit to the unit.
11.9V battery:
For power supply of the audio interface using a 9V battery.

1. Both microphones and high-impedance music instruments such as electric guitars or electric
bass guitars can be connected to the Mic/Instrument inputs:
• Connect microphones(balanced or unbalanced) via XLR plugs or 6.3mm jacks. Balanced
cables provide +6 dB more output and guarantee a better protection against interference in
case of long cable runs.
• For phantom-powered microphones a +48V phantom power can be switched on. Connect
high-impedance music instruments via 6.3mm jacks.
2. For connecting a signal source with line level output(e.g. CD player) use the stereo RCA IN
connectors(white jack = left, red jack = right).
3. For the amplification or recording of the preamplified signals of the Mic/Instrument inputs
and RCA IN and the signals from the computer connect a PA amplifier for speakers or
subsequent units with line level to the R/L balanced 6.3mm jacks OUTPUT.
4. Use the USB cable to connect the audio interface to an available USB port on your computer.
The audio interface is compatible with both PC and Mac computers and requires no
installation procedure or drivers for the correct functioning.
5. To monitor the analog input signals and the signals from the computer connect stereo
headphones with 3.5mm plug to MONITOR output. Alternatively, a monitor system such as
desktop speakers may be connected to the output.
6. For connection of a digital audio signal in S/PDIF format use the S/PDIF IN jack. The input
can only be used in connection with a computer.
7. A subsequent digital audio device with S/PDIF input can be connected to the S/PDIF OUT
jack to pickup the signals from the computer. The output can only be used in connection with
a computer.
8. For an operation independent of the computer the audio interface can also be supplied with
power via the supplied power unit or battery:
• Connect the cable of the power unit to the power input 9V AC/DC and the power unit to a
power outlet. Use the unit only with the supplied power unit. Always disconnect the mains
connector when you wish to change connections, move the unit to a different place or if it is
not used for a longer period.
• To insert the battery remove the battery cover. Insert the 9V battery as indicated in the
battery compartment. Close the compartment again with the cover. If the audio interface is
not used for a longer period(approx. 1-2 weeks), please remove the battery to prevent
damage in case of battery leakage.
NOTE: Batteries are hazardous waste which need to be disposed of appropriately. If
the device is to be disposed, the batteries have to be removed first. Make sure that the
poles are correct when inserting the battery. Never let batteries lying around openly as
there is the danger that these can be swallowed by children or domestic animals.
Immediately consult a doctor when batteries are swallowed! Leaking or damaged
batteries can cause irritations when getting into contact with the skin. In this case use
appropriate protective gloves. Make sure that the batteries cannot be short-circuited,
thrown into the fire and be charged. There is a danger of explosion. Should any liquid
enter the device nevertheless, remove the batteries immediately.

OPERATION
1. Switch on the audio interface with the POWER button. The button lights red.
2. As soon as the audio interface is switched on it is recognized by the computer as USB audio
device.
3. With the button MIC/LINE adjust the Mic/Instrument inputs to the connected sources:
• button pressed: input switched to high-impedance instrument level.
• button released: input switched to microphone level.
4. When using phantom-powered microphones, switch on the +48V phantom power at the XLR
inputs. For this purpose, press the PHANTOM +48V button. The +48V phantom power LED
lights red.
NOTE: If the phantom power is switched on, no microphones with unbalanced output
must be connected. Otherwise these microphones may be damaged. During the
stabilization phase(approx. 1 minute), you must not change any connection.
5. With the Mic/Instrument L/R controls and RCA IN control adjust the amplification for the input
sources to such an extend that the corresponding Signal LED lights green. The overload
indication Clip LED should not light or only light shortly during signal peaks. If it lights
permanently. turn back the corresponding control.
6. With the MIX control adjust the desired signal source for the analog outputs of the audio
interface:
• left position PREAMP: preamplified signal of the input source.
• right position CPU: audio signal coming via the USB connection.
• center position MIX: both signal sources(PREAMP and CPU) can be heard.
7. Adjust the desired main output volume and headphone volume with the LEVEL control.
