The D Series from Penton Audio USA are desktop paging microphones. Each has a very directional, super-cardioid pickup pattern helpful in allowing the unit to be used at normal distances in critical gain-before-feedback situations. Model DSM2010 (S for switch) has a momentary Press-to-Talk switch. The DSM2000 includes that P-T-T switch along with a smaller lock-on switch. Each model has a dynamic, moving coil, low-impediance capsule with neodymium magnet mounted inside a turned aluminum case. The capsule is mounted on a thin adjustable mini gooseneck, which in turn is mounted on a zinc diecast base with stylish ABS cover. All D Series microphones have a 5-conductor cable that is nearly 10' long. The cable is connected at one end to the base with the other end stripped and tinned for customer preferred and supplied connector.
