The m501 is Grace Designs 500 series module version of the venerable m101 mic preamplifier. Now the signature transparency and detail of Grace circuit designs is available for your 500 series frame.While the 500 series market has plenty of colored mic preamplifier options, the natural, musical clarity of the m501 makes it a welcome addition to the field. This circuit is for audio engineers who are confident with the quality of the source, mic section and placement, and wish to capture it with as little coloration or distortion as possible.The m501 module is a balanced, transformerless preamplifier, with 48V phantom power, a 75Hz HPF and a 1/4″ HI-Z instrument input. Also standard is Grace Design’s exclusive ribbon mic mode, which raises the mic input impedance, bypasses the input decoupling capacitors and deactivates 48V phantom power to protect delicate ribbon mics from damage.Large diaphragm, vintage ribbon or trusty dynamic-the Grace Design m501 brings out the very best in any microphone and takes the guesswork out of your input chain.Balanced, transformerless preamplifierGrace’s exclusive ribbon mic mode48V phantom power75Hz HPF1/4″ HI-Z instrument inputFits 500 series frame

The Grace Design model m801 8-Channel Studio Preamp delivers unmatched audio performance – with massive headroom and ultra-wide bandwidth which contribute to a markedly open, musical character. The m801 is designed to effortlessly resolve even the lowest level ambient information, resulting in a sonic picture of astonishing clarity and detail, which serves to capture the essential character of the music being recorded.The m801’s signal path has been hot-rodded to be fully balanced from start to finish, resulting in wider dynamic range, while new higher current output drivers enable even longer cable runs without signal loss. Included on each channel is a dedicated ribbon microphone switch, which shifts the preamplifier’s entire gain range up 10dB while deactivating 48V phantom power and bypassing the decoupling capacitors. And we’ve added an additional set of 8 channel balanced outputs for sending signals to a secondary recorder, workstation or console.While its predecessor now takes its place in pro audio history, the new m801 faithfully furthers the tradition of breathtaking audio performance and perfect reliability in a beautiful and functional 8 channel package.Redesigned, fully balanced, transformerless designHigher-current outputs drive even longer cable runsRibbon mic mode switchFast, musical transimpedance amplifier architecturePrecision 24 position gold contact rotary switch gain controls48V phantom power, 20 dB attenuator and phase reverseNo electrolytic capacitors in the signal pathSealed gold contact relays for all signal switchingLarger, two color, bi-phase LED peak indicatorRegulated linear power supply with custom wound toroidal transformerHighest quality components used throughoutFive year warranty on parts and labor

Grace Design M101 Microphone …

Grace Design M101 Microphone  ...Grace Design – Grace Design M101 Microphone Preamp
In 2000, the Grace Design model 101 microphone preamp helped fuel a revolution. When people took professional recording into their own hands, it was there with all of the quality and performance of a high-end mic preamplifier, but with a price that made it available to the masses. Eight years later, and the cause moves forward with the newly redesigned m101 preamp.Maintaining Grace Design pedigree throughout, the m101 employs balanced, transformerless, transimpedance circuit topology. With incredible bandwidth and headroom, the m101 is natural, musical and detailed, allowing engineers and musicians to consistently record vibrant, amazing tracks.The m101 is equipped with a redesigned universal switching power supply that’s dead quiet and accepts input voltages from 100 to 240V AC. The front panel is a tough black anodized/laser etched black, which ensures legibility and usability in varying light conditions. And all preamp functions have a dedicated indicator LED, including the 48V phantom power and HPF switch.Built in as standard is Grace’s unique Ribbon Mic Mode, which bypasses the input decoupling capacitors, raises the input impedance from 8.1k to 20k, and defeats the 48V phantom power, preventing damage to delicate ribbon mic elements. Ribbon mics, you’re welcome.The gain range is 10-75dB, including the additional +10dB of gain available with the output trim control. This provides ample gain for use of any type of microphone in any recording situation. The gain control is a precision gold-plated, 12-position switch, and the circuit path is built with 0.5% metal film resistors.Included is a HI-Z input on the front panel. Rear panel I/O options include both balanced TRS and unbalanced TS 1/4″ outputs, along with the standard XLR balanced out and XLR microphone in.Equally at home amplifying a vintage condenser mic or a plugged-in acoustic guitar, the m101 delivers the kind of high fidelity performance prFast and musical transimpedance architectureUpdated audio path with 0.5% precision metal film resistorsNew 12 position gold-plated rotary gain switchHigh performance output line driver amplifier and HPF amplifierRibbon mic mode (also great for dynamic mics)- Relay bypass of phantom power decoupling capacitors, increased input impedance, and 48V lockoutWider 10-75dB gain rangeEnhanced RFI interference suppressionThree output connectors: XLR balanced, TRS balanced and 1/4″ unbalancedBombproof laser-etched black anodized front panelSealed gold contact relay for Hi-Z input switchingBuilt in power supply / no wall-wartLed indicators for +48V, Ribbon mode, and HPFFive year warranty on parts and laborMade in the USA
