      Zoom TAC-2 Two Channel Thunderbolt Interface (109986430)

Bus-pwered audio interface.

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

    As reviewed by Aaron on 10/6/2014

    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.
