SK 2000Bodypack Transmitter

FEATURES

   20 fixed frequency banks with up to 64 compatible presets in up to 75 MHz switching bandwidth and 6 user banks

   Switchable RF output power: 10, 30, 50 and 100 mW (XP only) to further incre- ase distance range and multi-channel capability

   External charging contacts for rechar- ging BA 2015 in the transmitter

   Input sensitivity range of 60 dB can be adjusted in 3 dB steps

   Transmitters can be configured in the receiver menu and can be synchronized via the infrared interface

   Enhanced AF frequency response espe- cially for bass guitar (25....18000 Hz)

This lightweight yet extremely rugged bodypack transmitter is a delight for both the musician and the audience. With an AF frequency response of 18 to 20,000 Hz, it transmits even the sound of a bass guitar with rich fundamentals. Three RF output powers (four inclusive the US version) provide longer transmission ranges or more channels per frequency ran- ge. The rechargeable batteries of the SK 2000 (optional) can be charged right in the unit using the external charging contacts.

ARCHITECT’S

SPECIFICATIONS

The device shall be a portable compact bodypack transmitter for use with a com- panion receiver as part of a high reliability wireless radio frequency transmission system. The portable transmitter shall operate within a RF frequency range of 516 – 865 MHz in 20 fixed frequency banks or 6 user banks with a maximum of 64 presets with a switching bandwidth of maximum 75 MHz tunable in 25 kHz steps; carrier frequencies shall be maxi- mum 3000. Nominal/peak deviation shall be ±24 kHz/±48 kHz. Frequency stability shall be ≤ ±15 ppm. RF output power shall be selectable at 10 mW (Low), 30 mW (Standard), 50mW (High) and 100 mW (Maximum, XP version only). A compan- der feature shall be included and shall be Sennheiser HDX system with pilot-tone squelch (switchable). Audio frequency response shall be 80 – 18,000 Hz (micro- phone) and 25 – 18,000 Hz (line).
