Grace Design has released its latest 500 series rack preamp module, the m501. Designed for audio professionals in the music recording, film scoring, broadcast and fixed installation markets, the m501 reportedly provides the sonic performance and feature set of the company's m101 preamp for customers using 500 series racks.
br />The fully balanced, transformerless m501 signal path incorporates 0.5 percent precision metal resistors, output line driver and HPF amplifiers, and RFI suppression. The 12-position rotary gain switch is gold-plated, and a sealed gold-contact relay is used for Hi-Z input switching. There's also a rotary trim/gain pot for fine-tuning of gain settings. The m501 includes Grace's ribbon mic mode as standard, which helps to provide a 10-75 dB gain range.
