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

I looked at preamps for a long time. I always read people saying things like "It helps my tracks sit in the mix better." and that they could "hear a difference". Now I see what they mean. I couldn... read more [+]'t tell you that this sounds different or more clear than my MOTU ultralite's preamps... But when I listen to my finished mix, it definitely does sound clearer and just right. It's an obvious difference but I can't tell what is different. It just sounds better. close [-]

After some extensive research, I recently purchased the Focusrite ISA One and the UA Solo 610 from my good friend, Mark Bruhn, at Sweetwater. What this did was give me a very nice and well respected S... read more [+]olid State Transformer based preamp and a very nice and well respected Tube preamp for not a whole heck of a lot of money (per se ;-).
I'd recommend the ISA One to be anybody's first preamp as it is so versatile, it sounds really great and the price is outstanding. The mic preamp itself has 4 impedance settings with the 110 being my favorite. Adding the DI and other goodies is just icing on the cake, especially at this price point. If they'd only make it (and the UA Solo 610) as a rackmount unit ;-) close [-]

This is a great unit

I learned a lot after buying this unit. One thing is that besides monitors, a preamp is the most important buy one can make for a home studio. This amp is not one to color your sound with any cha... read more [+]racter. What I found is that it is crystal clear. I was able to change the sounds of my recording by changing mics, adjusting mic positions, etc, to get the sound I wanted. It picks up the full spectrum of sound that is fed into it and leaves you with plenty of room to eq what you don't want. . My recordings were immediatley improved and I can now hear the individual tracks more clearly and more pronounced.. The impedance matching feature is an amazing feature that will get the best sound out of your mic. Spend your money where it counts. This is an amazing preamp and you won't regret buying it. close [-]

Our Customers Say...

My Sales Engineer is the best. If I need it tomorrow, I have it tomorrow. He makes sure everything is in order and that I'm set up right. I've spent a lot of money at other places, too, but I don't remember them calling me to make sure everything's okay.
