Overview
  • 1Description

The m201 from Grace Design is a two channel microphone preamp that features massive headroom, ultra-wide bandwidth and an open, musical character. Grace has always been known for producing highly accurate and clean preamps, long favored by classical and live-to-tape/disc engineers. This translates into recorded sounds that possess extreme clarity, and helps preserve the integrity and character of the original source.

The preamp provides a hefty amount of gain for most microphones. Ribbon microphones traditionally require higher gain to operate properly, and providing this has often come at the expense of additional noise. The m201 has a dedicated ribbon microphone mode that shifts the gain range up by 10dB without the addition of noise. The mode simultaneously disables phantom power, while bypassing the decoupling capacitors and optimizing the input impedance.

Included is M+S decoder circuitry with a built-in width control and a dedicated set of XLR outputs. The main outputs have parallel outputs, allowing the user to send the microphone source to two separate recording devices or mixers. Each channel also features Hi-Z inputs for amplifying electric instruments. Phase reverse switches and a 20dB pad are available per channel, as are bi-color LED peak indicators.

  • Grace Design AD Option for m201

    The AD Option for m201 from Grace Designs is a two channel analog-to-digital converter module option for the m201 microphone preamp. The module provides low-latency 24-bit/192kHz conversion and delivers a high level of sonic clarity, detail and nuance.

    Either the microphone preamp section, or the M+S matrix can be routed to the converter input directly for use in standard recording applications. Using the additional analog line inputs, the microphone preamplifier and A/D converter sections can be used separately, allowing for external processing to be inserted between the preamp and the converter.

    External Wordclock or Digidesign LoopSync synchronization is available utilizing a proprietary dual stage PPL with s-Lock, for extremely low jitter and greater stability. Two independent A/D sensitivity configurations are available from the front panel, allowing the user to easily switch between two calibrated settings, each of which can be configured to one of four provided standard A/D sensitivities.

    Note: The module is field installable but requires a competent technician for installation.

    Low latency analog-to-digital converter capable of up to 24-bit/192kHz operation
    Selectable input source include microphone preamp channels 1 and 2, MS matrix L-R output and external balanced line inputs
    Four output connectors types - AES3 on XLR, AES3-id/S/PDIF on BNC, and TOSLink optical
    External synchronization to Wordclock or Digidesign LoopSync
    Dual stage PLL clock recovery. Wide range low noise VCO based PLL followed by Grace's crystal based s-Lock ultra low jitter PLL
    Two input sensitivities selectable on the front panel, each is independently calibrated
    Twenty-segment peak reading LED meters show 60dB range
    AES3 outputs can be configured for single or dual wire operation
    Four standard sensitivities are supported:
    +18dBu = 0dBFS (14dB headroom), +20dBu = 0dBFS (16dB headroom), +22dBu = 0dBFS (18dB headroom), +24dBu = 0dBFS (20dB headroom)
