Warning

Operation using an AC adapter

Never use any AC adapter other than a ZOOM AD-19.

Do not do anything that could exceed the ratings of outlets and

other electrical wiring equipment.

Before using the equipment in a foreign country or other region

where the electrical voltage differs, always consult with a shop that carries ZOOM products and use the appropriate AC adapter.

Alterations

Do not open the case or modify the product.

Caution

Product handling

Do not drop, bump or apply excessive force to the unit.

Be careful not to allow foreign objects or liquids to 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 c ould be splashed by

wa te r.

Do not use in places with frequent vibrations.

Do not use in places with much dust or sand.

AC adapter handling

When disconnecting the power plug from an outlet, always pull on

the plug itself.

Disconnect the power plug from the outlet when the unit will not

be used for a long time and whenever there is lightning.

Connection cables and input/output jacks

Always turn the power OFF for all equipment before connecting any

cables.

Always disconnect all connection cables and the AC adapter before

moving the unit.

Volume

Do not use at a loud volume for a long time.

Interference with other electrical equipment

In consideration of safety, the has been designed to minimize its emission of electromagnetic waves and to suppress interference from external electromagnetic waves. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves could result in interference if placed nearby. If this occurs, place the

and the other device farther apart.

With any type of electronic device that uses digit al control, including the

, electromagnetic interference could cause malfunction, corrupt or

destroy data and result in other unexpected trouble. Always use caution.

Cleaning

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

Breakdown and malfunction

If the unit becomes broken or malfunctions, immediately disconnec t the AC adapter, turn the power off and disconnect other cables. Contact the store where you bought the unit or ZOOM service with the following information: product model, serial number and specific symptoms of breakdown or malfunction, along with your name, address and telephone number.

FCC regulation warning (for U.S.A.)

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from

• that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Introduction

Thank you very much for purchasing a ZOOM LiveTrak ( ). The has the following features.

12-channel digital mixer & multitrack recorder

The combines a digital mixer with 12 total input channels (8 mono and 2 stereo), a multitrack recorder that can simultaneously record up to 14 tracks, and a 14-in/4-out

USB audio interface. Compact and lightweight, this digital mixer is easy to transport and can even be used with PA systems for live performances in rehearsal studios, cafés and other small venues.

High-quality mic preamps

The has high-quality mic preamps built-in for 8 channels. The high-quality analog inputs, which can provide +48 V phantom power, have a −128 dBu EIN rating and +60 dB

maximum input gain. In addition, channels 1 and 2 also support Hi-Z input, while channels 3 to 8 have PAD functions (26 dB attenuation), enabling them to accept high levels of input.

5 MONITOR OUT channels

In addition to the MASTER OUT, the also has 5 MONITOR OUT channels. The MONITOR OUT mixes can be set separately for each output. Since these support head-

phone output, headphones are all that are needed to send different mixes to each performer.

Digital mixer that can be operated intuitively

Opening menus is not necessary with the . Every mixer parameter can be controlled with knobs and keys just like an analog mixer. Each channel has a 3-band EQ,

and the mono channels have compressor functions. The mixer also includes high-quality send effects. In addition, up to 9 mixer status scenes can be saved in the unit.

Recorder can simultaneously record 14 tracks and play 12 tracks

The can simultaneously record every channel and the master fader stereo signal output for a total of 14 tracks. Since the recorded data is saved in 16/24-bit, 44.1/48/96

kHz WAV format, the files can easily be copied to a computer and used in a DAW. In addition, overdubbing and punching in/out can be done as expected with a multitrack recorder.

14-in/4-out USB audio interface

The can be used as a 14-in/4-out USB audio interface. The signals from each input and the master fader output can be recorded in a DAW. In addition, signals output

from a computer can also be assigned to a stereo channel. Class compliant mode, which enables connection with iOS devices, is also supported.
