The Radial McBoost is a high performance microphone signal booster designed to elevate the output of a typical dynamic microphone for greater transient response and boost the signal of a low-output ribbon mic to bring it up to a usable level for mixing consoles or preamps that may not provide sufficient gain.

• 25dB signal booster for dynamic & ribbon mics
• Extends dynamic range and microphone reach
• Uses standard 48V phantom for power
• 3-position load switch and high-pass filter

The 100% discrete class-A circuit design begins with a dual-transistor J-FET circuit to produce up to 25dB of gain without introducing noise, color or artifact. Each individual transistor is carefully measured and batch-sorted to comply with the design specification to certify performance. As with all Radial products, the circuit board is then loaded into a 14-gauge, I-beam, reinforced steel enclosure to prevent outside stress from torquing which otherwise could lead to premature part failure. A book-end cover creates protective zones at each end to safeguard the switches, potentiometer and connectors from the rigours of the road.

Merely connect the McBoost in-line using standard 3-pin XLRs and activate 48V phantom to provide power. Select between three impedance settings to optimize the response and then reduce low-frequency clutter with the 3-position high-pass filter. The McBoost will elevate the output to produce added clarity, excitement and extra drive for long cables whether you are in a recording studio, on a live concert stage or in a broadcast center.

I've been using both the SM7B and the SM58 as input for my home computer's video conferencing system. I had been receiving feedback that my voice sounded muffled. Pushing the gain on my Scarlett 8i6 also boosted the noise inherent in the system. A quick visit to the store, and store associate recommended the McBoost as an addition to my mics. The McBoost is a plug-and-play device and BOY does it do a fantastic job. My voice sounds SUPER crisp and it really does a fantastic job of keeping the noise out. Definitely recommended!!! This is an EASY to boost your signal twice as strong (i.e. my input volume is at 50% and i'm louder than I was at 100% before the McBoost). Note: The device runs on phantom power (48V) so make sure you also pair this with a good set of balanced XLR cables. Note (at least on the 8i6) phantom power DOES NOT run through the 1/4" section of the combo port. It MUST be XLR, so stick with XLR all the way through (i.e. not an XLR to 1/4" cable).
