Miniature Headset Station (Beltpack) with XLR Adapter CableWe have been asked many times for a lighter, smaller beltpack. Simply shrinking the BP1 was not an option because its size is actually determined by the space required for three XLRs on the back, and the size allowed us to insert second circuit boards to create products like the BP1SL and BP2. Our response is the BP.15 beltpack. We've retained the aluminum extrusion, impact resistant front and back bezels and recessed controls that are what makes the BP1 'bullet-proof'. To shrink the size, we sacrificed the headset and the loop-through XLRs on the back and used a smaller circuit connector. We offer an optional accessory cable to convert from the smaller connector back to XLR, and an optional Y-cable to allow looping onwards to the next station in the circuit. For a neater less cumbersome solution we suggest using the SB1 Splitter Box. The actual circuit of the BP.15 is identical to the BP1, so it sounds the same. The size of the BP15 is approximately that of a deck of playing cards.
The BP.15 continues our tradition of superior performance, now in a tiny package, 1/7th (0.15) the size of our BP1 (by volume). All the functions of a full-sized belt pack are retained. The signal button and the mic. On/Off button are shaped differently for easy recognition by touch, in the dark. Two LEDs are mounted, one to indicate signaling (red, bright) and one (green, low output) to indicate that the microphone is On. The BP.15 is available with an optional vibrator in addition to the standard signal LED. The volume control is a thumbwheel, again reducing the likelihood of accidental damage. There are two recessed controls. One controls 'sidetone' - the sound of your own voice which you hear in your own earspeaker. The second recessed control adjusts the sensitivity of the microphone input circuit to allow for different outputs of dynamic and electret microphones. The microphone input circuit includes a limiter which keeps the microphone input from being overloaded, causing distortion. The amplifier circuit delivers a crisp, clear signal to the earspeakers for excellent speech recognition, but with a wide enough frequency response to minimize the possibility of ear fatigue during a long performance. Miniaturization has its costs. The size will not accommodate the conventional three XLR jacks on the bottom (rear) panel. The 4-pin headset jack had to be retained but we have substituted a miniature XLR-type jack for the other two. The BP.15 comes with a cable constructed from a length of our steel reinforced cable with the miniature plug on one end and a 3-pin female XLR on the other. A second cable is available with the miniature plug on one end feeding into a Y with a male XLR on one leg and a female on the other for looping onward to the next station in the system.
Our BP1 has a long reputation for ruggedness and reliability. The BP.15 incorporates the very same characteristics that earned the BP1 those accolades. The cabinet is a strong, aluminum extrusion with internal ribbing which not only adds to its strength but provides for support of the printed circuit board along the full length of both sides. The durable end bezels deflect damage. The same (almost indestructible) belt clip used on the BP1 is used on the BP.15. Realizing that belt packs are bound to live a rough life, we take every possible opportunity to secure components and 'ruggedize' the complete product.
Simple, quick assembly has kept the cost of the BP.15 very competitive. Use of only the best available components results in a low predicted incidence of warranty repairs - probably the most important cost savings of all.
