Grace Design m101 Overview

The m101 from Grace Design is a single-channel microphone preamplifier that uses the same fast, musical transimpedance amplifier architecture as the model 801 and model 201, but packaged and priced to be within the reach of any recording engineer, musician or studio. The preamp now employs 0.5% precision metal film resistors.

An upgrade from the model 101, the unit still employs fully balanced, transformerless circuit topology and has no electrolytic capacitors in the signal path. With incredible bandwidth, headroom and resolution, the unit is remarkably natural, musical and detailed. A universal power supply is internally mounted.

The m101 features a ribbon microphone mode which provides additional gain that is usually required by that type of microphone. Pushing the dedicated ribbon switch does three things. Phantom power is locked-out to prevent potential damage to ribbon microphones, the impedance of the microphone input is raised from 8.1kΩ to 20kΩ, and the 48V DC blocking input capacitors are bypassed with sealed gold contact relays.

The included instrument DI input is designed to accommodate a wide variety of high impedance input sources, making the unit an excellent choice as a DI box which will flawlessly preserve the sound of any plugged-in instrument while imparting lackluster sounding instrument pickups with clarity and detail.

Straightforward and Low Noise

I use these with MXL 603s's. Now it's time to look into better mics and a sound-insulated room. I tried no mics and got much much less noise, then 100 ohms across the signal pins and got even less noise. Didn't measure the noise; merely listening, with headphones, to the output amplified by a Panasonic HDC-Z10000. I like the idea of the rotary switch, instead of a pot, for the gain control. It has a pot for the trim control, so it has the best of both worlds. Construction is very good with high-quality connectors and controls. It's pretty cool to have a five-year transferable warranty.

The Grace 101 is a bargain. For beginner or expert you can't go wrong. Portable enough to take with you and a must in studio. Very easy to use with amazing sound. COZ ((VOICE)

this is the best preamp value on the market that ive found.....used a avalon in a friends studio, and owned a ua la-610 in my own studio....both of these preamps are 1500 dollars or more, and are not as clean and crisp sounding as the grace designs preamp....and where other preamps take a degree to figure out how they work, and take a LONG TIME to get set to prefrence, this little gem is SIMPLE and very EASY to fine tune....for under seven hundred dollars, this is a professional preamp needed to make the leap from home studio to professional turnkey studio, and buy it from BHPHOTO, they are the best

All of the equipment and software I have purchased I never woke up to learning how much difference a pre-amp at this level makes. Instruments: Bass guitar, lead guitar, acoustic guitar - it is amazing the fullness it pulls out of these instruments, and that is fullness with headroom. A great addition for voiceovers.Now on the microphones: tested on our condenser mics (Schoeps and AT 4053b) and our Dynamic (Beyerdynamic, Shure) mics. It is hard to put into words the differences. Present system: ProTools, Focusrite Saffire 56, ArtPro Channel pre's, Presonus pre's. This is a game changer investment. Spend it here before you drop the extra $ on the mic.

Most transparent

I am well pleased with the Grace Design m101 mic preamp. I recorded vocals & guitar using the AKG C3000 through the Grace Design m101 then into my Apogee A/D converters. WOW! The m101 is certainly the most transparent mic preamp, in the price range, that I have heard. The signal to noise ratio on this unit is extremely high. I did a recording in a noisy room, using the microphone close to sound source and the recorded signal had very little ambient noise. Moreover, the signal that I captured through m101 sounded clean and full. It accurately represented the sound source.

This preamp is outstanding!

I'm using the Grace Design M101 to boost my Sure SM7B mic. It plugs into a UAD Apollo Twin Duo X Thunderbolt which plugs into my MacBook. I do conversation level voice recording for online course creation. I get more clear gain than I need for my mic, which outputs notoriously low signal. If you're in the market for an outstanding preamp and are OK with the price, this is an option worth exploring.

Hi I have apollo twin x (Quad) and i have buy preamp GRACE m101 . Should I have Converter between these two equipment? If yes What is it the best converter for voiceover and for this equipment??
Asked by: Saif
A converter is not necessary. Simply come out of the 1/4-inch TRS balanced output to the 1/4-inch portion of the combo input of the Apollo Twin X Quad. It is important to send the signal into the Apollo as a line level signal, to take advantage of the Grace preamp.. A Pearstone PM-TRS 1/4&quot; TRS Male to 1/4&quot; TRS Male Interconnect Cable (6'),BH #PEPMTRS06 would be a good choice for a balanced cable.
