The new HD-4 features twin sensors and a neat little jack assembly. New smaller and thinner sensors fit easily under the strings of most hammered dulcimers. The sensors adhere to the soundboard with the supplied double sided tape. The jack assembly (which can store any excess lead wire from the sensors) mounts securely to the front of the instrument with 3M VHB tape. Mono or Stereo - An internal selector switch within the jack box allows you to choose between mono or stereo output. Technical Each HD-4 sensor has 18 inches of shielded cable. The Jack Box has a standard size 1/4" output jack. Dimensions: HD-4 sensor - Length 1.7" x Width 1.3" x Height 0.32" (43mm x 34mm x 8mm) HD-4 jack box - Length 2" x Width 1.4" x Height 0.80" (50mm x 35mm x 20mm) View the installation instructions for the HD-4 (pdf) Amplification This pickup has been designed to operate properly and sound terrific without the use of a preamp when plugged into any 'normal' amp (guitar amp, bass amp, etc.) As with any pickup, the sound can be further enhanced with an outboard preamp. If you require the ability to plug directly into a P.A. or mixer then you may wish to add our Mini Pre belt clipable preamp.
