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.
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.
That's what the manufacturer has to say...... What we say is that you you can create sonic bliss with the Radial Engineering McBoost. Take any standard dynamic mic, hook it up to the McBoost , plug into your preamp/mixer and blamo! your "blah", weak sounding mic is transformed into an amazingly hi-end, broadcast quality, sonic weapon. The McBoost takes the unused phantom power portion of your mixers channel or preamp and turns it into an additional 25 db's of volume. If your mixers preamp only outputs 60 db's well here is an additional 25 db's boosting your mixer or preamp up to a whopping 85 db's of sound turning your mic and mixer/preamp into aural bliss! It's a "must have" for any audio engineer in the studio or the field.
