Here are the Best Studio pre-amp reviews on SoundReview.
These can be used to power certain Studio mics, headphones, guitars and synthesizers. As a matter of fact, the Zoom Tac-2R, provides functionality for not only mics, but direct inputs for guitar and synthesizers with an included midi output. When recording tracks in your home studio, the light weight design helps you add to the mix without taking up too much desk space.
It’s important to realise, pre-amps such as the Scarlett 6i6 use a combination of hardware and software to run the system. As a result, it is recommended to check the Studio pre-amp supports your computer operating system.
Are you running a high class studio? Then consider spending more to produce better audio results!
If you are looking for more inputs and outputs, there’s usually an upgrade available. In this instance, the unit would look like more like a rack. This is better for recording larger bands where more channels are being used.
For applications such as headphones monitoring, the Sennheiser HDV 820 can provide amazing audio output. It is really expensive, so we wouldn’t expect anything less for $2400. The AEA TRP is another higher tier unit designed as a ribbon mic pre-amp, these guys aren’t joking around either. A top of the range piece of kit, little to disappointed about!
Overall, the Focusrite Scarlett 2i4 is a competitively priced unit which offers a good feature set and quality construction. It also delivers with regard to sound quality. The unit does however present ongoing crashing issues for some users.
Good feature set
Fairly rugged construction
Looks and sounds good
Technical issues were experienced by a number of users
The Focusrite Scarlett 6i6 is a good value purchase if you want to get into home recording. The dual headphone outputs are a nice inclusion. The cheaper Scarlett 2i4 is a better buy for portable recording and has a better physical interface though.
Lots of connectivity options for a competitive price
Pretty sturdy overall
Two headphone outputs with individual controls is a nice feature
Less suited to portable recording than the 2i4
Instrument pre-amps aren't very inspiring
Pad and line/instrument switch is done via software rather than control panel
