Additional Features

Of course, there is way more to the iD14 than what was listed previously.

Here is some additional information on this interface that you can check out!

1. 10-in 6-out interface

If you’re a big fan of being able to expand your equipment, you’ll definitely get hooked on the Audient iD14’s interface!

What sets this apart from most interfaces is that it includes more inputs and outputs!

Regular 2-in, 2-out interfaces, give you two channels to record and two channels to monitor.

Expanded interfaces give you EVEN MORE opportunities to record, like with a 10-in, 6-out interface.

2. iD Button

Don’t you just love multifunctional buttons?

The iD button is one of the most popular, and one of my favorite, aspects of Audient’s interfaces. It offers the following:

  • Volume control
  • Dim
  • Mono Sum
  • Polarity Reverse
  • Talkback

The volume control of the iD button also lets you convert it to a virtual scroll wheel, which helps you dial in settings and adjust faders!

3. Burr-Brown Converters

The Audient iD14 has powerful converters which offer high sound quality. This can help you pinpoint possible points of improvement even faster!

They also offer the following:

  • Dynamic Range (ADC): 120 dB
  • Dynamic Range (DAC): 126 dB

Did you know that the Audient iD14 has 4 outputs?

This means that you can use up to TWO sets of speakers to listen to your home recording!

You can also use the extra outputs to connect to an external headphone amp so that you can send your mix.

6. JFET Instrument Input

I recommend the iD14 f you want to emulate the inputs of classic valve amps.

The Audient iD14 has a powerful JFET instrument input that offers a stable sonic foundation for your guitar!

7. ADAT Input

The Audient iD14 supports both ADAT and SPDIF, which gives you the ability to add up to 8 extra microphone pre inputs!

These ensure that you have the perfect setup for holding music production sessions on a larger scale!

What Are Their Key Differences?

What Are Their Key Differences-

Now that I’ve rundown both devices, it’s time to see how one device is different from the other in terms of the following aspects:

  • Technical Specifications
  • Performance
  • Sample Rates
  • Latency
  • Pricing

Technical Specifications

The iD4 has the following technical specifications:

  • 2 x Multi-Segment LED Meter
  • 1 x 1/4″ TRS Unbalanced Headphone Output
  • 2 Inputs / 4 Outputs at 96 kHz (Analog)
  • 8 Inputs / 0 Output at 48 kHz (Digital)
  • No high pass filter

The Apollo Twin MKII has the following technical specifications:

  • 5 x Multi-Segment LED Meter
  • 1 x 1/4″ TRS Unbalanced Headphone Output
  • 2 Inputs / 6 Outputs at 192 kHz (Analog)
  • 8 Inputs / 0 Output at 48 kHz (Digital)
  • 4 Inputs / 0 Outputs at 96 kHz (Digital)
  • 2 Inputs / 0 Outputs at 192 kHz (Digital)
  • A 75 Hz high pass filter
  • Built-in processors that help you run plug-ins on your own without needing to exhaust your laptop’s resources

WINNER: Between the two interfaces, the winner is the Apollo Twin MKII!


One of the age-old questions essential for purchasing the best type of device is, “How well does it perform?”

The iD14 has the following technical specs:

  • 10 Hz to fs/2 ±0.1 dB (A/D D/A)
  • 20 Hz to 22 kHz ±0.1 dB (Min Gain for Microphone & Line)
  • 20 Hz to 22 kHz ±0.1 dB (Max Gain for Microphone & Line)
  • 101 mW into 30 Ohms (Headphone Power, Max)
  • 64 mW into 60 Ohms (Headphone Power, Max)
  • 39 mW into 600 Ohms (Headphone Power, Max)
  • 24-Bit (Bit Depths)
  • ADAT, Internal, S/PDIF (Sync Source)

The Apollo Twin MKII has the following technical specs:

  • 20 Hz to 20 kHz ±0.1 dB (Microphone, Line, Hi-Z)
  • 20 Hz to 20 kHz ±0.1 dB (Monitor, Line, and Headphone)
  • 80 mW into 600 Ohms (Headphone Power, Max)
  • 24-Bit (Bit Depths)
  • ADAT, Internal, S/PDIF (Sync Source)

While both devices include excellent components and benefits, determining the winner of this round would depend on the type of performance, you’re looking to get from them.

WINNER: Between the two interfaces, if you’re looking for the best type of performance, the winner is the Apollo Twin MKII!

Sample Rate

The sample rate for the iD14 ranges includes the following:

  • 44.1 kHz
  • 48 kHz
  • 88.2 kHz
  • 96 kHz

On the other hand, the Apollo’s rates can increase to 192 kHz.

While having higher rates might sound appealing, it’s important to consider that humans can often hear frequencies that range between 20 Hz and 20kHz. [R]

In addition to this, you would most likely convert the music files to either 44.1 kHz or 48 kHz after you’re done with the recordings, so I recommend sticking with one format for consistency.

WINNER: Between the two interfaces, the winner is the iD14!


In regards to latency, the iD14 processes

  • 6.52 ms at 44.1kHz (depends on the type of buffer size)
  • 4.65 ms at 96 kHz (depends on the type of buffer size)

On the other hand, the Apollo Twin MKII processes 1.1 ms at 96 kHz (input to output).

WINNER: Between the two interfaces, the winner is the Apollo Twin MKII!


One of the most important factors to consider before purchasing an interface is PRICE.

While the exact price can differ depending on your preferred supplier, the Audient iD14 is often sold at $229, while the Apollo Twin MKII is often sold at a whopping $1,099.

I’d normally say “you get what you pay for,” but the Apollo Twin MKII’s price is a big ask, so the iD14 wins here.

WINNER: Between the two interfaces, the winner is the iD14!
