Uni-Directional Microphones
--------------------------------------------------------------------------------
The system consists of a right-angled mount (D) to which is screwed the electronics package (C). The capsule itself (B) is screwed to (C) and the diaphragm is protected by cap (A). The capsule (B) is available in 3 forms:
* Omni-directional
* Cardioid
* Hypercardioid
The latter 2 are uni-directional.
The advantage of the uni-directional capsules is that there is less likelihood of feedback occurring and bleedthrough from other instruments is minimised
The system can be mounted on a gooseneck of the appropriate length for any particular instrument.
The bass contact microphone is attached to the underside arch of the bridge by means of double-sided tape. photo 2. The best way to do this is to use differential tack tape so that the microphone can be easily removed without damage. The procedure is to line the inside of the bridge with the D/S tape. Remove the backing paper and place the contact microphone on the low tack surface that is exposed.
The contact microphone can also be combined with a capsule microphone. The two devices are connected to a single pre-amplifier having separate volume controls for each device but with a single output. This can be attached to the tailpiece of the Bass on the inside or outside.
Both the contact microphone and the capsule microphone are terminated in female mini XLR sockets, as is standard with Accusound products. The output from the pre-amplifier is a full-size male XLR.
These systems are also available as wireless systems.
