The K nig & Meyer (K&M) 24010-300-55 Boom Microphone Clamp enables a microphone clip (and subsequently a mic) to be mounted via a boom arm to an existing microphone stand. The boom arm is fully adjustable to enable precise positioning. Perfect for miking an acoustic instrument whilst the main mic stand takes care of the vocal microphone duties. Alternatively for non-singing musicians the main stand can accommodate a K&M 19712 or 19710 iPad holder (ideal for the use of interactive music apps). Easy to mount at the specific height you require via a prismatic clamp connector which can accommodate pole diameters from 15mm to 22mm. The ⅜" thread enables a suitable microphone clip to be attached (an optional ⅜" to ⅝" thread adaptor can be used for ⅝" threaded clips).
