Radial Engineering McBoost Microphone Signal Intensifier

There is something about Radial products that just charms. Sure, it's the rugged I-Beam construction, a standard in production excellence that seems perhaps lost on a lot of today's musical equipment manufacturers, but it's more than that. The McBoost is an example of what makes Radial users such loyal customers. It is a microphone signal booster that increases the output of dynamic microphones for greater transient response, or boosts the notoriously low-outputsignal of a ribbon mic to usable levels for mixing consoles or preamps that may not provide enough gain.

The 100% discrete Class-A circuit design begins with a dual-transistor J-FET circuit to produce up to 26dB 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 rigors of the road.

Simply 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 from the microphone. 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.
