The has the following features. 18-in/20-out USB3.0 Audio Converter The is 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 to an iPad. Since it also supports recording and playback at up to 24-bit/192kHz, it can also be used for the playback of high-resolution sound sources delivered with superior audio quality over the Internet. Attention to audio performance An asynchronous transfer system that is not impacted by computer jitter is used.The latest AD/DA converter, which supports 192 kHz, is used. So, the entire system reproduces the original audio faithfully. Built-in high-performance mic preamps The high-performance mic preamps are based on those developed for our H Series. Hi-Z input is supported. The gain can be raised by up to 60 dB, and +48V phantom power can be supplied. Flexible built-in mixer and dedicated mixer application The has a built-in mixer that allows you to freely route up to 20 output channels from among the 18 input channels and 20 computer playback channels. By using the application designed for this interface, you can make settings for the built-in mixer and monitoring effects from a computer. For details about , see the ZOOM website (http://www. zoom.co.jp/downloads/). Please read this manual carefully to fully understand the functions of the so that you can make the most of it for many years. After reading this manual, please keep it with the warranty in a safe place.
03 Usage and Safety Precautions Usage and Safety Precautions Safety Precautions In this operation manual, symbols are used to highlight warnings and cautions that you must read to prevent accidents. The meanings of these symbols are as follows. Warning Something that could cause serious injury or death Caution Something that could cause injury or damage to the equipment Other symbols used An action that is mandatory An action that is prohibited Warning Warning 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-19. Always hold the AC adapter itself when disconnecting it from an outlet. Warning 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 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 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. Usage Precautions 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 digital control, including the , electromagnetic interference could cause malfunction, corrupt or destroy data and result in other unexpected trouble. Always use caution. Rack mounting If you are unable to mount the in the rack you are using, remove the rubber feet from its bottom panel. 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. 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 the should malfunction or operate abnormally, disconnect it immediately. 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.

(→ P . 11) NOTE When shipped new from the factory, the AD/DA converter upsampling function is enabled. This will cause operation with a 4x sampling rate when the sampling rate is 44.1/48 kHz. See the Reference Guide to disable it. Upsampling When the original sampling rate is 44.1 kHz or 48 kHz, internal processing can allow operation at 176.4 kHz or 192 kHz (enabled when shipped new from the factory). This eliminates aliasing noise from the sound during A/D conversion and makes the sound with D/ A conversion even clearer than before.
