High-quality microphone preamp compatible with API 500 modules: The m101 has earned an unwavering reputation as a high-quality single-channel microphone preamp. Its superior sound is now available for the VPR Alliance (API 500 module). GRACE design's signature sound, with its stunning spatial reproduction, delivers a sound that captures everything without coloration or distortion.
Many of the microphone preamps compatible with the API 500 series are vintage-style designs that tend to be overly "colored," so the arrival of a head amplifier like the m501, with its transformerless design and emphasis on acoustic reproduction, has been eagerly awaited. Among the API 500 series modules, no other microphone preamp can reproduce music so beautifully with the speed and resolution of the m501. This is truly a long-awaited unit.
In addition to the same balanced transformerless circuit design as the m101, it also features a well-thought-out 75Hz high-pass filter, a top-quality DI input that brings out the instrument sound, and a "ribbon microphone mode" that is also effective with dynamic microphones.
Among the many API 500 compatible modules available, such as compressors and EQs with unique sounds, choosing the GRACE design m501 as your microphone preamplifier, which offers clear and high reproduction of the original sound, will be of great significance in terms of bringing out these distinctive sounds.
