UT General Technical Description Introduction The UT Digital Hybrid Wireless™ handheld transmitter uses state-of-the-art wireless technology with a highpowered 100mW RF output and a unique microphone capsule arrangement. The VariMic™ preamp allows the user to custom-tailor the microphone’s response to suit the application. Three capsules are available for this transmitter: a cardioid condenser, an omni condenser and a super-cardioid condenser.
Synthesized UHF Hand-Held Transmitter Compatibility Modes The transmitter was designed to operate with Lectrosonics Digital Hybrid Wireless™ receivers and will yield the best performance when doing so. However, due to the flexibility of digital signal processing, it is also able to operate with Lectrosonics 200 Series, Lectrosonics 100 Series, IFB and certain non-Lectrosonics analog receivers in special compatibility modes.
UT Controls and Functions Power On/Off Switch A Power On/Off switch located on the outside bottom of the unit turns the unit on and off. The function of the Power On/Off Switch can also be changed so it also operates as an audio mute switch. In this configuration, the Power LED doubles as a battery status indicator (in the unmute or On position) and an audio mute/unmute indicator (in the muted or Off position). (See Operating Instructions, Power Switch Function Selection.
Synthesized UHF Hand-Held Transmitter Opening the Battery Compartment Audio Level Control The Audio Level control (under the Battery Compartment Cover) is a thumbwheel used to adjust the audio input gain for proper modulation. Locked Mode The UT can be placed in a locked mode where the Power switch and the Frequency Switches are disabled. This protects the unit from accidental power-off or misadjustment after it has been prepared for use.
UT VariMic™ Controls Caution: Due to the high RF levels surrounding the transmitter, the sound of the VariMicTM capsule may be temporarily affected if the metal windscreen is not in place. Always make the final decision about sound balance and quality with the windscreen in place. The VariMicTM head includes adjustments for Bass (LO), Midrange (MID) and Treble (HI) response. There is also an attenuation adjustment to provide up to 15 dB of additional headroom if needed.
Synthesized UHF Hand-Held Transmitter Subsonic Noise Filter In addition to the tone controls, the UT also has a builtin subsonic noise (or high pass) filter. This filter is fixed and cannot be adjusted or defeated. Low frequency noise is much more of a problem with wireless microphones than with conventional microphones.
UT Changing Capsules 1) Remove windscreen 2) Loosen and remove the two socket head bolts that attach the capsule to the microphone body 3) Lift capsule assembly 4) Disconnect 3-pin connector Caution: Avoid damaging the coiled wire under the capsule. 5) Connect new capsule 10 6) Set new capsule assembly to align the holes for the socket head bolts LECTROSONICS, INC.
Synthesized UHF Hand-Held Transmitter 7) Insert and tighten both socket head bolts 8) Replace windscreen Note: Older units may have phillips head bolts. Please use the supplied socket head bolts to install the new capsule.
UT Operating Instructions Selecting Compatibility Mode 4) Rapidly toggle the Power Switch Off and On. This transmitter is capable of working with Lectrosonics 400 Series Digital Hybrid Wireless™, 200 Series, 100 Series, and some analog wireless receivers from other manufacturers. (Contact Lectrosonics for details.) The transmitter must be set for compatibility with the matching receiver, which is easily done using the supplied screwdriver and a battery.
Synthesized UHF Hand-Held Transmitter On/Off Switch Function Selection The On/Off switch can be configured to control power or to function as an audio mute switch. When it is configured as an audio mute, the transmitter power can still be turned off by starting with the switch in the On position, then toggling it three times within five seconds (ending in the Off position). The Audio Mute mode will persist between power cycles until it is changed with the following procedure.
UT Battery Installation The transmitter is powered by a standard alkaline, lithium or LiPolymer rechargeable 9 Volt battery. Alkaline batteries will provide about 3.5 hours of operation, a lithium battery about 6.5 hours, and a LiPolymer battery about 4 hours per charge. Note: The battery status lamp will function normally only with alkaline or lithium batteries.
Synthesized UHF Hand-Held Transmitter Operating Notes The Audio Level control should not be used to control the volume of the overall sound system or recorder levels. This gain adjustment is used to match the transmitter gain with the user’s voice level and microphone position. If the audio level is too high — both Modulation LEDs glow red frequently. This condition will reduce the dynamic range of the audio signal.
UT Troubleshooting SYMPTOM POSSIBLE CAUSE UT POWER LED OFF 1) Battery is inserted backwards. 2) Battery is dead, or too low to be used. UT MODULATION LEDs OFF 1) Audio Level control turned all the way down. 2) Battery is in backwards. Check Power LED. 3) Mic capsule is damaged or malfunctioning. Contact the factory for repair. 4) Attenuator on VariMic™ preamp board is set for too much attenuation. RECEIVER RF INDICATOR OFF 1) 2) 3) 4) UT not turned on.
