Radial Engineering McBoost Microphone Signal Intensifier
Mic Signal Booster, Class-A FET with 25dB Gain, Load Adjust and Filter 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
