Active Partners
The Apollo Twin Quad MKII sounds incredible. Analog-to-Digital conversion takes place in the 24-bit realm, at speeds of up to 192 kHz, delivering audio of the highest fidelity. Noise, distortion, and other conversion artifacts are effectively eliminated. Plus, the Thunderbolt platform is rock-solid, offering more stability than that of USB or FireWire – and near-zero levels of latency. More than an interface, the Apollo Twin Quad MKII is a supportive collaborator, bringing its own processing power to the party. Inside are four SHARC floating-point DSP processors from Analog Devices. Their extra processing power really comes into play when using UAD plug-ins, as they won’t bog down your computer’s CPU.

All are Welcome
The Apollo Twin Quad MKII offers a variety of inputs in a host of configurations. Inputs 1 and 2 feature XLR/Balanced TRS 1/4" combo jacks that can accept a low-impedance (Lo-Z) mic signal or a balanced/unbalanced line level signal. Up front is a convenient high-impedance (Hi-Z) jack, allowing an instrument such as an electric guitar to connect directly to the interface. Configurable in the included Console software, the optical input can read up to eight channels of incoming digital audio in ADAT or S/PDIF formats.
Unison Enabled
Unison compatibility allows the software and the hardware to interact in new and creative ways, delivering an astounding level of audio accuracy and fidelity when using UAD plug-ins to recreate the sound of classic preamps. Unison-enabled hardware preamps – such as those found in the Apollo Twin Quad MKII – can change their electronic characteristics at the circuit level to more accurately satisfy the needs of the emulation software.

Whether your UAD software is emulating a preamp design from Manley, Neve, SSL, API, or Universal Audio, vital characteristics of the original circuitry — such as input impedance — are recreated in the hardware before digital conversion takes place. And once again, the processing power of the Apollo Twin Quad MKII handles much of the heavy lifting for your computer’s CPU.

Preamp Performer
The onboard mic preamps – in addition to being Unison compatible – offer a surprising range of control, available at the touch of a button. From the Universal Audio Apollo Twin Quad MKII itself, you can choose the Mic or Line input; engage a low-cut (75 Hz) filter; apply phantom power; add a 20dB pad; reverse the phase; or combine both inputs as a stereo pair.

Monitor Maven
The Apollo Twin Quad MKII provides impeccable sound quality at the input stage and delivers glorious, pristine audio on the way out. The level knob – the only knob – feels solid and inspires confidence. A surrounding halo of LEDs point to the current setting.

Switching from the Preamp Mode to the Monitor Mode calls up a host of additional features. The talkback module features a built-in mic that can be used to talk to the talent or to slate tracks for production. The dual-function TALK button allows momentary of toggle operation of the talkback module. The DIM button drops the monitor level to a more comfortable level for conversation, without the need to physically change the output level setting (knob). Like the Talkback button, the DIM button provides momentary or toggle operation. Pressing the ALT button switches the Main Monitor mix to an alternate set of outputs. The MONO button sums both channels to a mono signal, and the MUTE button kills the main outputs. The MONITOR SELECTED indicator conveniently switches to RED, to remind you that the MUTE function is on. The Mute feature does not affect the headphone output.

Out and About
The Apollo Twin Quad MKII is equipped with two sets of outputs – Monitor Outputs 1 & 2 and Line Outputs 3 & 4. Both sets of signals are delivered through balanced TRS 1/4" jacks. The Monitor outputs are controlled by the Monitor Level and the additional Monitor button functions. Line Outputs 3 & 4 can be configured using the included Console software.

What is your opinion of this product?
Unison is incredible technology! The best sounding plugins on the market, with no latency, powered by a solid piece of hardware, with improved converters, expanded DSP power, and improved functionality! What’s not to like?

Truly the best. Perfect in every way
What is your opinion of this product?
While it is true that the sound quality and the plugins are as good as advertised, the size and multiple purposes of the interface make it the ultimate for its price range and grade. If you aren’t working in the studio, but you need that kind of bang, this is the one. Watch out though, if you are new to universal plugins, they are that good and that expensive. Look for preamps, compressors and eqs to make your recording that much more legit.

Nice, but For PCs there are issues
What is your opinion of this product?
PC users be very wary as this device needs a add in Thunderbolt 3 card that costs anywhere between $100 -$299 and then you have to buy another $100 adapter from Thunderbolt 2 to Thunderbolt 3 adapter so the investment is close to another $200 or $300 just to get going. The product is very nice, but for PC users its much more expensive to get up and going.

Absolutely phenomenal
What is your opinion of this product?
The way I listened to music was completely changed when I decided to get this wonderful work of art. Perfect for everything I need it for, not to mention that the preamps on this are top quality and make anything you put through it sound crisp and clean. So glad I waited for the MK2 to come out! UA really outdid themselves this time!
