ARCHITECT’S & ENGINEER’S

SPECIFICATION

The Samson Concert Series IV VHF Wireless System shall be of a single-channel, crystal-controlled oscillator type operating on selected frequencies from 174.6 - 213.2 MHz. The

System shall include a beltpack or handheld transmitter and a receiver, and shall allow operation of at least thirteen simultaneous systems on separate channels. The transmitter and receiver shall incorporate compander circuitry for noise reduction and maximum dynamic range.

The receiver shall provide a balanced microphone-level output on a male XLR-type connector and an unbalanced microphone-level output on a 1/4

″ phone connector. The unit shall have a 5 segment AF level meter indicating 10%,

25%, 75%, 100% and 125% of audio signal. The audio output level shall be adjustable with a variable attenuator. The receiver shall incorporate a power LED and dual LEDs for carrier indication. The receiver shall have an automatic signal sensing squelch circuit with a variable attenuator. The receiver shall incorporate Microprocessor True Diversity circuitry for automatic antenna switching. The receiver shall use two

12 VDC powered 1/4-wave removable antennas on M-J connectors. The receiver shall be powered by 115 Vac, 50/60 Hz via a supplied 12 VDC adapter. The receiver shall be notified under FCC rules, Part 15, and DOC certified under RSP 121.

The receiver shall be of a rack-mount type. Dimensions of the receiver shall be 19

″

(480 mm) wide, 3.8

″

(96 mm) deep and 1.7

″

(44 mm; 1 rack space) high. Weight of the receiver shall be 3 lb. (1.4 kg).

The beltpack transmitter shall provide either a microphone-level input on a Switchcraft TA3F P3-type connector or an instrument-level input on a 1/4

″ phone connector. The beltpack audio input sensitivity or handheld microphone output level shall be adjustable with a variable attenuator. The transmitter shall provide a mute switch. The transmitter shall incorporate a battery strength LED and shall use an internal dipole antenna. The transmitter shall be powered by a 9 V alkaline battery and shall provide a nominal battery life of not less than 18 hours. The transmitter type shall be accepted under appropriate FCC rules. Dimensions of the beltpack transmitter shall be 2.6

″

(65 mm) wide, 4.3

″

(110 mm) deep and .9

″

(22 mm) high. Weight of the beltpack transmitter shall be 3.1 oz. (90 g). The System shall carry a three-year warranty.

The System shall be a SAMSON CONCERT SERIES IV VHF
