1 USER MANUAL Passion for innovation Model T500-CLOUD Multi-Channel FM Transmitter 2 About this Manual Read this user manual carefully before installing and operating your T500 CLOUD FM Transmitter. Use the product only as described to avoid accidental injury, damage or hearing impairment. Also, read safety warnings carefully. Keep this manual for future reference. If you give this product to someone else, remember to include this manual. Package Contents (1) T500 CLOUD FM Transmitter (72-76 MHz) (1) Antenna (1) Power supply (1) User manual System Overview Thank you for choosing the Enersound T500 CLOUD FM Transmitter. This professional transmitter is designed for assistive listening and language interpretation. It wirelessly broadcasts a speaker’s voice, music or any audio signal up to 1000 ft. (305 m). The audience can use the optional R-120 FM multichannel receiver or any other compatible FM receiver operating on the 72-76 MHz frequency to pick up the broadcast. The T500 CLOUD FM Transmitter features 3 main audio inputs that allow the direct connection of virtually any analog audio source, including a 3.5 mm jack for headset microphones, an XLR & ¼ inch combination jack with a selector for dynamic microphones, condenser microphones or line-level signals, and a RCA line auxiliary input. It also has a recording output and a 3.5 mm monitor headphone jack. For language interpretation, it has a unique integrated interpreter monitor function. This feature allows interpreters to select an external incoming audio source and utilize a headset with microphone to listen to the source language without the need of an interpreter console or external headphone amplifier. Through the headphones’ volume control, interpreters can set the desired incoming audio level and the [MUTE] button allows them to momentarily silence their microphone for coughing or sneezing. For more advanced interpreting functions, it can also be utilized with the Enersound IC-12 multi-channel interpreter console or with any other interpretation platform with analog audio outputs. Its LCD display allows to easily program the various useful functions, such as test tone, RF power level, display mode (frequencies or channel numbers), and channel lock. 3 Quick Reference: Controls, Displays and Connectors Front panel (1) POWER button: Press & hold for 5 seconds to turn on/ off device. (2) Power indicator (3) Front microphone mute button: Press to mute/unmute front microphone. (4) Mute indicator light (5) Mic input, 3.5mm jack (6) Main volume control: Adjusts audio output volume. (7) Headphones volume control (8) Up button: Changes channel/frequency up. During setting mode, press to modify selection. (9) Menu button: Press & hold for 6 seconds to access setting menu.

(11) Headphones output, 3.5mm jack (12) Internal/external monitor source selection switch: Set to EXT for language interpretation applications to monitor an external audio source (speech to be translated). Set to INT to monitor the broadcasted audio. (13) Internal selection indicator (14) External selection indicator (15) LCD screen (16) (17) Audio level indicators (18) Audio peak indicator 4 Rear panel (19) Remote antenna connector Used when top mounted antenna is not convenient, for example when rack mounting. Use only ONE antenna connector at a time. (20) External monitor Input Used in language interpretation applications. The audio source to be translated should be connected here so the interpreter can listen to the source language. This signal will NOT be broadcasted to FM receivers. (21) Recording output This RCA jack contains a mix of Input 1, Input 2 and front 3.5 mm microphone. It can use for external signal out, the impedance is 10k ohm. (22) Input 2, RCA jack Connects unbalanced audio signals to be broadcasted. It can use for Aux input jack, the impedance is 10k ohm. (23) Gain Adjusts Input 1, Input 2 and front mic gain level. (24) Input 1 mode selector Selects line level, microphone level, or microphone with 12V phantom power for condenser mics. (25) Input 1 Accepts balanced or unbalanced connection of a microphone or line level input. This combination jack accepts either XLR or ¼” plugs. (26) Power supply jack Used with the included 15V power supply. (27) USB-C Connector-- This is used to connect the Laptop’s USB jack, it can use to read & record the music audio signal between T500-CLOUD & Laptop. 5 Set-up Instructions General Set-up Instructions: Unpack the transmitter Remove outer packaging and plastic cover. Inspect for physical damage and immediately report any issues. Position the unit Position the transmitter near the audio source (sound system, mixer, interpreter desk, etc.), away from metallic objects that might interfere with the antenna. Connect the antenna For tabletop use, screw in the antenna connector onto the transmitter top antenna connector. Alternatively, an optional remote antenna can be used. Do not use two antennas at the same time. Rack mount the unit (optional) The transmitter can be rack mounted, if necessary, in a 19’’ rack using the optional rack mount kits: single-unit RM-501 or double-unit RM-502. Dual rack mount RM-502 for 2 T500 CLOUD FM Transmitters NOTE: If rack mounting, do not use the top antenna connector; you will need to use the rear connection antenna with a 90 degree adapter AD-590 or use the optional rack-mount antenna kit RAK-500 available for purchase. If needed, you may also use a remote antenna. Only use original Enersound antennas. Check with your authorized Enersound dealer or visit www.enersound.com to view available accessories. • Power the Unit Plug the power supply into the power connector on the rear panel, then connect the power supply into an outlet. Only use the Enersound approved power supply. (The PS-500 is an auto switching power supply th…
