Introduction
2-in/2-out USB3.0 Audio Converter
Theis an audio converter with a SuperSpeed USB3.0 interface.
In addition to supporting Windows and Mac, using class compliant mode it can also be connected toan iPad. Since it also supports recording and playback at up to 24-bit/192kHz, it can also be used for theplayback of high-resolution sound sources delivered with superior audio quality over the Internet.

Attention to audio performance
The entire system reproduces the original audio faithfully. An asynchronous transfer systemthat is not impacted by computer jitter is used along with the latest AD/DA converter, which
supports 192kHz.

Built-in high-performance mic preamps
The high-performance mic preamps are based on those developed for our H Series. Eachinput also supports Hi-Z connections. The gain can be raised by up to 60 dB, and +48V
phantom power can be supplied.

Warnings
Alterations
Do not open the case or modify the product.

Operation using an AC adapter
Never use any AC adapter other than a ZOOM AD-14.
Always hold the AC adapter itself when disconnecting it from an outlet.
Do not do anything that could exceed the ratings of outlets and otherelectrical wiring equipment or supply power other than AC100V.
Before using the equipment in a foreign country or other region where
the electrical voltage differs from AC100V, always consult with a shopthat carries ZOOM products and use the appropriate AC adapter.

Precautions
Product handlingDo not drop, bump or apply excessive force to the unit.
Be careful not to allow foreign objects or liquids enter the unit.

Operating environment
Do not use in extremely high or low temperatures.
Do not use near heaters, stoves and other heat sources.
Do not use in very high humidity or where it could be splashed by water.
Do not use in places with frequent vibrations.
Do not use in places with much dust or sand.

Connection cables and input/output jacks
Always turn the power OFF for all equipment before connecting anycables.
Always disconnect all connection cables and the AC adapter before
moving the unit.

In consideration of safety, thehas been designed to minimize its
emission of electromagnetic waves and to suppress interference from external
electromagnetic waves. However, equipment that is very susceptible to interferenceor that emits powerful electromagnetic waves could result in interference if placednearby. If this occurs, place theand the other device farther apart. With
any type of electronic device that uses digital control, including the,electromagnetic interference could cause malfunction, corrupt or destroy data andresult in other unexpected trouble. Always use caution.

Usage and Safety Precautions

Usage and Safety Precautions

Cleaning
Use a soft cloth to clean the exterior of the unit if it becomes dirty. If necessary, usea damp cloth that has been wrung out well. Never use abrasive cleansers, wax orsolvents such as alcohol, benzene or paint thinner.

Temperature considerations
Continuous use of this interface for long periods of time, for example, might cause it
to become warm. This is normal as long as it does not become too hot to touch.

Breakdown and malfunction
If theshould malfunction or operate abnormally, disconnect it immediately.
Then, contact the retailer where you purchased it or Zoom support and provide thefollowing information: product model, serial number and details of the symptoms
of malfunction or abnormal operation, as well as your name, address and telephone
number.
