JTS PROFESSIONAL SPT-1T UHF PLL True Diversity Receiver Instruction Manual

Notes for system operations

• Before connecting the power, check that the power requirement shown on the unit is the same as the power output on the adaptor supplied.
•  Do not leave the unit at where the humidity and temperature are high.
• Dry your hands before operating the system.
• Keep the unit away from fire and heat source.
• Turn the volume to minimum at both the mixer and amplifier before setting up the system.
• When multiple transmitters are stacked at the same time, it is recommended to use the same group of frequency points to avoid frequency interference.
• Caution : The suitable environment for this product is with a temperature between -10°C (14°F) and +50°C (122°F).

Features

• The UHF band PLL frequency oscillation mode is used for the transmitter. The receiver utilizes a broadband 36MHz line design, with a total of six groups 1441 frequency points that can be selected, and a built-in mode of non-interference frequency.
• The SPT-1T transmitter combines JTS’ patented 2.4GHz REMOSET wireless transmission technology with highly stable circuitry and signal performance, to synchronize frequency and channel settings to the SPT-1R receiver just by pressing a button. The SPT-1R can be used in a wide range of projects and performance venues.
• With the BNC dual antenna receiver terminal, it can increase the receiving distance and eliminate reception noise or radiated noise interference.
• The SPT-1R is compact, cable-free, and can be used by simply attaching itto the speaker. It provides users with six self-contained groups to avoid interference and perfectly reproduce all frequency bands.
• Problem of audio delay is easy to be solved, providing users with: metric feet (0~272 m), feet (0~892 feet) and time (0~800 ms) are converted to three settings for faithful audio signal performance.
• The wireless speaker transmission system transmits audio signals through the SPT-1T and receives them through the SPT-1R, eliminating complicated wiring problems and realizing wireless surroundings.
• Two channels, transmitting on different, non-interfering frequencies, can be used for left and right channel or individual channel transmission.
