In today's world, speed is everything. The blazingly fast Zoom TAC-2 interface uses the latest Thunderbolt technology for ultra-low latency and the ultimate in high-quality audio, up to 24-bit/192kHz. Lightweight and portable, the TAC-2 is also easy to use, with a single large rotary knob controlling all parameters.

Thunderbolt: The ultimate in high-speed connectivity
More than twice as fast as USB 3.0-not to mention twenty times faster than USB 2.0 and twelve times faster than Firewire 800-Thunderbolt is the interconnection technology of the future. Co-developed by Apple and Intel Labs, it allows signal to be transferred at an incredibly fast 10 gigabits per second, which means virtually no latency.* Thunderbolt interfaces such as the TAC-2 are also unaffected by computer jitter (slight variations in timing), so there's no need to connect an external master clock source.

The TAC-2 performs 4-times upsampling during both analog-to-digital and digital-to-analog conversion. In other words, when the sampling frequency is set to 44.1kHz or 48kHz, the TAC-2 processes the signal at high resolution 176.4kHz or 192kHz. For A/D conversion, this means less aliasing noise; for D/A conversion, this means increased clarity and fidelity.

* Latency time in the TAC-2 is just 4.17 msec round trip when operating at a 44.1kHz sampling rate with a 64 sample buffer size.

The Ins and Outs
The Thunderbolt port on the rear panel carries digital signal to and from your computer as well as carrying power to the TAC-2. Two combo XLR/TRS inputs are provided for the connection of mic- and line-level signals, and there's a handy Hi-Z (high impedance) unbalanced input on the front panel for direct connection of passive electric guitars and basses using a standard ¼" guitar cable. The TAC-2 also offers two balanced TRS output jacks which allow you to connect the TAC-2 to your monitors, as well as a dedicated ¼" stereo headphone jack.

The TAC-2's single rotary control knob is used to set input, output and headphone levels and to provide +48 volts of phantom power to the selected input, allowing you to use the TAC-2 with any kind of microphone, from low-cost dynamics to expensive studio-quality condensers. Seven-position LEDs show continuous signal strength as well as input/output overload clipping.

Zoom TAC-2 MixEfx
TAC-2 MixEfx is a free Macintosh application designed specially for the TAC-2. With TAC-2 MixEfx, you can set mix parameters and add high-quality effects such as reverb and echo. Other features include a low cut filter, phase reverse, AUTO GAIN control for each input. There's also a LOOPBACK function that allows you to blend the input signal and playback signal for zero latency. TAC-2 MixEfx has three memory slots for saving user settings with quick recall.

A One Trick Pony, minus the trick


from Los Angeles

Comments about Zoom TAC-2 Two Channel Thunderbolt Interface:

At 128 buffer and 96 sample rate OSX/Live9 the recorded rtl latency was 6ms, (greater than the RME UCX usb interface). Any lower settings and click/pops occur if you actually have any real plug ins loaded. The Tac2 "reports" a round trip latency of 2.67 to Ableton preferences. But real world (minus computer process time) =6ms. To suggest that "thunderbolt is 20x faster than usb 2.0" as an marketing ploy? I ask of Zoom faster how? Width or Ping time? 2 channels is a raindrop in the width of thunderbolt so how could the Tac2 utilize thunderbolts strength? It is not faster, its actually slower. The loopback function is a good idea but you need spare channels for such as thing. I mean your monitor becomes the loopback so how in Tarnation do you listen? I need something that's portable for playing out. And struggle justifying buying the TAC2 over just using the headphones jack which is only slightly slower on a mac. If it at least had an extra channel of output for click track or aux monitor it might be useful I think Tac 3 and 4 might be coming out soon. Will wait for those before considering. In the meantime will return this one In fairness however, if you only need a small 2 channels at a good low latency for reasonable $$ this will work.
