Introduction

Thank you very much for purchasing a ZOOM TAC-8 Thunderbolt™ Audio Converter.

The TAC-8 has the following features.

18-in/20-out Thunderbolt™ audio converter

The TAC-8 audio converter uses Thunderbolt™, the latest generation of high-speed interface technology. With this, we have realized a system with low latency that was not possible using USB 2.0. Since it supports recording and playback at up to 24-bit/192kHz, it can also be used to play back high-resolution sound sources and deliver them 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 TAC-8 MixEfx mixer application

The TAC-8 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 TAC-8 MixEfx application designed for this interface, you can make settings for the built-in mixer and monitoring effects from a computer.

For details about TAC-8 MixEfx, see the ZOOM website (http://www.zoom.co.jp/downloads/).

Please read this manual carefully to fully understand the functions of the TAC-8 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.

Sampling rates and inputs/outputs

Sampling rate	Analog inputs/ outputs	S/PDIF inputs/ outputs	ADAT inputs/ outputs	Total inputs/ outputs
44.1 or 48kHz	8/10	2/2	8/8	18/20
88.2 or 96kHz	8/10	2/2	4/4	14/16
176.4 or 192kHz	8/10	2/2	2/2	12/14

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 / 48kHz . See the TAC-8 MixEfx 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.
