best-cheap-audio-interface-for-amp-simulators

One day, a good recording session goes wrong when our good old audio interface / sound card suddenly stops working without prior symptoms, then we need to find a cheap replacement as soon as possible with only $100 left on our bank account. So, the hunt for the best cheap audio interface / sound card begins….

We realized that with such a small budget we can’t expect much, but at least there’s some minimum criteria we need to set. Anyhow, here are our criteria for the (cheap) new audio interface:

  • Less than $100
  • Decent, good instrument pre-amp(s) for its price will be critical since we use it mainly for amp simulators.
  • Good driver for both Mac and Windows.
  • Can handle as small latency as possible* (critical for amp simulator users)
  • Not overly complicated to setup and use. We play guitars not a tech admin aren’t we?
  • Decent monitoring output a.k.a. transparent. so you can hear your processed guitars better
  • Small and portable. Until we have enough money to get a much better quality audio interface/ sound card, it will serve as a portable backup audio interface for mobile purposes. e.g. playing live with amp simulators
  • USB 2.0 connection, just because an Audio Interface / Sound Card with thunderbolt or firewire ones will cost pretty much higher.
  • On the technical sides, here’s some specifications that needs to be present, or nice to have:
    • Input:
      • Microphone  input with  pre amplifier for using Microphone with or without phantom Power (+48v) to a studio condenser microphone via an XLR socket
      • Instrument  input – TS/TRS cable for guitar and other line signal sources, HI-Z input. Subjectively, we prefer Hi-Z instrument input with 1 MΩ impedance (Based on our experience this gives the best clarity and sound when using amp simulators).
      • MIDI – connecting MIDI keyboards , drumpads, MIDI controllers. Not any amp simulator users need one, but it’s nice to have one.
    • Output:
      • Headphones monitoring the audio with Headphones
      • Monitors stereo outputs on back of the audio interface for Studio Monitors
      • USB Interface for connection to your computer

*Some notes on low latency drivers:
Depends on your CPU power.  For playing guitars, really low latencies will increase CPU usage. You may experience audio artefacts a.k.a “crackles” and “pop’s”. But any of current modern CPU processors should be able to handle the audio stream. We are using i3 and i5 processors at the moment from the “third generation” of Intel Processors and apparently, they are powerful enough 🙂


**Some important tips for better performance and low latency (Useful when you using a Laptop and playing amp simulator)

Make sure you use USB 2.0 port!

Go to general power management of your computer:
Start > Control Panel > System and Security > Power Options.
Power Scheme to High Performance

For Power Options, change advanced power settings:
Hard disk > Turn off hard disk after > Setting (Minutes) = Never
Sleep > Sleep after > Setting (Minutes) = Never
USB settings > USB selective suspend setting > Setting = Disabled

Processor power management > Minimum processor state > Setting = 100%


Behringer U-Phoria UMC204HD ($79.99)

CONS:

  • No Driver! although ASIO4ALL can be used.
  • Some users report the DI inputs do not sound good with high-Z instruments.  But that’s subjective…
  • please try with your guitars and respected amp simulators. It depends on your guitar and pickups!
