From Our Research Team:

A Forte in a portable unit!

Built on the topology of the original ISA 110 including the Lundahl L1538 transformer and bespoke zobel network, the Focusrite ISA One is an excellent way to tap into the legacy of the legendary Forte console in an ultra-portable format you can take anywhere you need to record. Inputs for microphone, line-level, and direct instrument-level sources cover all of the bases. A variable impedance selector also lets you dial in the warmth you want without sacrificing the clarity you need. Plus, the ISA One's DI and microphone level inputs run in parallel, so you can blend the direct signal of the instrument with the sound of the miked up amplifier - a killer trick for getting bass sounds that are both fat and punchy.



Focusrite ISA One Features:
  • Single Channel Original ISA Series Pre Amp in a portable metal Chassis
  • Selectable impedance, perfect for matching with any microphone
  • Direct Instrument inputs including high and low impedance options to provide a comprehensive DI solution
  • Classic VU meter, Ladder LEDs too-all manner of metering, at source
  • Cue mix stereo inputs
  • Certificate of origin hand-signed by Phil Dudderidge included
  • An optional 24 bit/192kHz A-to-D converter available

Focus is Right...

This is the difference in a project sound and a pro sound... seriously. Mics I have used for 20 years have totally new life. Not because they sound totally different, but because they sound perfectl... read more [+]y right, sitting snugly in the mix like my cat on a pile of clean laundry. There is a reason the circuitry here changed the recording field forever. If you're not quite ready to buy this, it should only be because you're saving up for two of them! close [-]

Great Pre!

I love this guy. It has to be the most versatile pre out there. It sounds good on everything. When I track, this is the last thing before my 192s.

Great with a mic on Vox or Guitar, as a Guitar preamp or pre amp sim

This is an excellent clean mic pre. If your looking for tons of color, this pre isn't for you but if you want to record what you hear, the ISA one, is the one.

I use the ISA one to record ... read more [+]acoustic guitar and it gives a great sense of "air" to the recording. As a Bass DI or a Guitar pre the ISA one shines. I never used to use amp sims as I wasn't happy with the sound. It turned out my problem was the preamp. My amp simulators never sounded so good. Remember, its much harder to clean up the "dirt" from a recording than to add it in later if needed.

If you want a "no color", "record what you hear" preamp,at a very resonable price the ISA One is it! close [-]

Great workhorse

by from California

I've owned this preamp for about 2 years now. Its 1/3rd of what I call the "Preamp Holy Trinity", the three types of pre's any engineer should own. Transformer based, transformer-less, and tube. This ... read more [+]is the transformer based pre. You can think of this as a relative to a Neve preamp. This preamp can be a little harsh on sibilance, which is pretty common for transformer based preamps. Having said that, this preamp excels on anything you need to capture with an airy open sound to it. It makes acoustic instruments shimmer with a ton of presence, which helps things stay up front in the mix (something that's difficult for tube pre's to do). It stacks really well, you can run all your tracks through this and they still won't muddy up too much. In fact there seems to be a nice cumulative effect with this preamp, the more you run through it, the more character your recording has. And the real shocker about this pre IMO is how amazing the DI sounds for bass. I have Radial's with custom transformers, and a few other great preamps to run through and yet the DI on this one does it right. It keeps the high end content of the bass right where you need it, making it a lot easier to mix in a dense mix and still be able to tell what the bass is doing. I was very shocked when I found out how good the DI sounds. I'm so impressed with how well this pre has performed that I'm going to sell it to upgrade to the whole channel strip ISA430. close [-]

Isa one with akg 414 vox

by Jason Cox from Phoenix

I thought I'd share my experience with my isa one and maybe it will help someone else.

I have a projectmix io as my interface which annoyingly doesn't have a pad on the inputs. Mix that... read more [+] with the fact that the isa one doesn't have an outPut volume control it means the Main out of the isa one is too hot for the ins. It is impossible to not clip. Even pushing main out to balanced line in (without the gain boost on the mic input).

To correct this, I go from the headphone out on the Isa one to a line input. This allows you to control output volume. However, doing this without also plugging in the output on the isa one into a mic input created an unusable amount of noise. I'm sure this is simply my inexperience, however with this all hooked up it sounds clean and amazingly quiet.

I should mention that I have a DBX compresser / de-Esser / gate -expander plugged into the insert of the isa one. The DBX 286s specifically.

This combo is fantastic for me and my ear.

For the price, the Isa one is just awesome!

Hope this helps someone else :) close [-]
