KSJ Audio Glair 500 Series Microphone Preamplifier

Precision Engineering Meets Practical Design

The KSJ Audio 500 Series Microphone Preamplifier delivers professional-grade audio capture in a compact, reliable package. Designed for the discerning engineer who demands both reliable performance and value. This 500 series module offers clean, transparent gain with thoughtful features that streamline your workflow.

Repeatable Control 

The front panel features high-quality Grayhill rotary switches for both its mic and EQ gain, which switch low-tolerance resistors for precise gain adjustment. Paired with buttons for 2x gain, phantom power, a 20dB pad, phase invert, 100hz highpass filter, as well as 2 selectable frequencies for the EQ, this makes it incredibly easy to dial in something that sounds good quickly.

Versatile EQ Section

Compact but versatile! The two selectable frequencies were chosen to offer you tone shaping possibilities in an area often over, or under-hyped, depending on the source and style of music. The boost and cuts modes at 4k and 14k allow you to correct the frequency responses of the mic at hand.  Boost for adding presence or air to vocals, acoustic instruments, or room mics without needing additional processing. Cut to add vibe or take the edge off an overlight bright mic! Combined with the 100Hz highpass filter, you have essential tone-shaping tools right at your fingertips.

Quality Components, Accessible Price

While modest in price, this preamp makes no compromises in component quality. Using low tolerance components, grayhill rotary switches and neutrik connectors, wima caps for the eq frequencies on a solid feeling unit with a black anodized front panel. The KSJ Audio Glair preamp delivers consistency and reliability that more budget gear often lacks. This attention to detail translates to cleaner recordings and better results for longer.
