Klark TeknikMIC BOOSTER CM-2 2-Channel Dynamic Microphone Booster with Preamps
1/5
Independent shopping perspective
The Korena take
The MIC BOOSTER CM-2 puts two channels of preamp gain in line with dynamic microphones. Each channel provides up to 25 dB of gain, helping bring the signal level up while allowing the mixer gain to stay lower. It runs from 48 V phantom power, so there are no batteries to manage. The compact metal chassis and balanced XLR connections suit dynamic-mic setups in the studio or onstage.
Strong match
Who this is for
- Two dynamic microphones needing up to 25 dB of added gain in a stage setup.
- Studio routing where lower mixer gain is desired after boosting dynamic-mic signals.
- Microphones placed near the booster to reduce noise from extended XLR cable runs.
Consider the trade-offs
When to look elsewhere
- Setups that cannot provide 48 V phantom power.
- Connections requiring more than the unit’s two balanced XLR channels.
