The Lectrosonics 100 Series wireless microphone systems, provide the quality and dependability expected of Lectrosonics. Completely portable and designed for camera mounting, this system includes the UCR100 camera mountable receiver and HM-21 Digital Hybrid Wireless UHF Plug-On Transmitter (Block 21).
The Lectrosonics UCR100 is a compact wireless microphone receiver designed for easy, convenient operation with smaller DV camcorders. The UCR100 offers over 256 selectable frequencies over a 25.6MHz band to avoid interference from local RF sources. Matching transmitters provide a full 100mW of output power, resulting in clean frequency transmission without virtually any drop-outs. The UCR100 output operates nominally at 0dBv (line level), but use with microphone inputs on camcorders can be achieved with an optional adapter cable. Frequency selection is achieved via recessed rotary switches located on the side panel. An easy access audio output adjustment knob is located in the front panel. The UCR100 is 9V battery powered and enclosed in a lightweight, durable, machined aluminum housing.
Lectrosonics 100 Series - UHF Portable Receiver (Frequency Block 21)
The Lectrosonic UCR100 is a compact wireless microphone receiver designed for easy, convenient operation with smaller DV camcorders, without sacrificing the quality that has become commonplace with Lectrosonic. The UCR100 offers over 256 selectable frequencies over a 25.6MHz band to avoid interference from local RF sources.Matching transmitters provide a full 100mW of output power, resulting in clean frequency transmission without virtually any dropouts.
In addition to the conveniently compact size of the receiver, an easy access audio output adjustment knob is located in the front panel. The UCR100 output operates nominally at 0dBv (line level), but use with microphone inputs on camcorders can be achieved with an optional adapter cable. Frequency selection is achieved via recessed rotary switches located on the side panel. The UCR100 is 9V battery powered and enclosed in a lightwieght, durable, machined aluminum housing.
Note: For system compatibility, the component's frequency MUST match your existing system/component frequency.
The UCR100 boasts an incredible 256 selectable frequencies over a 25.6MHz band which is effective in avoiding local Radio Frequency interference.
Powerful Output Power
Lectrosonics features an impressive 100mW of output power, giving the system the ability to operate up to 1,000' or more without dropout, depending on conditions.
Flexible Output Impedance
The UCR100 features a line level (0dBv) output impedance, although interfacing with camcorder style mic inputs can be achieved with an optional cable.
Along with its compact design, machined aluminum construction give the unit its durability on the road and against the elements.
The HM Digital UHF Wireless Plug-On Microphone Transmitter from Lectrosonics enables you to transmit the signal of any XLR microphone wirelessly. The HM transmitter overcomes inherent channel noise with its patented Digital Hybrid Wireless technology, which digitally encodes the audio. Digital conversion before transmission provides all of the benefits of conventional FM wireless systems, (range, resistance to interference, etc) without the noisy artifacts introduced by analog compandors.
The HM transmitter provides 256 user-selectable UHF frequencies. The input amplifier uses an ultra low noise op-amp for quiet operation. Gain controlled with a wide range dual envelope limiter, it provides over 30 dB of headroom above full modulation. A 24-bit A-D converter digitizes the audio, then filters supersonic noise above 21 kHz.
HM transmitters are backwards compatible with Lectrosonics 100, 200, and IFB series receivers; as well as being compatible with third-party analog receivers. Phantom power from its XLR input jack is selectable between 5, 18 and 48 volts, making the HM compatible with just about any condenser or dynamic microphone. It's powered by two AA lithium, NiMH, or alkaline batteries for up to 12.75 hours of use, with Phantom Power engaged (lithium).
The sound quality of the HM transmitter is outstanding. The power supply provides constant voltages, switching to accommodate the life-cycle of the batteries, resulting in an ultra low noise input amplifier. The excellent signal to noise ratio and dynamic range of the HM qualify it for use in the most demanding of professional applications.
The HM transmitter uses ±75 kHz wide deviation for an excellent signal to noise ratio and wide dynamic range.
Digital Hybrid Wireless Technology
Audio is encoded in the transmitter and decoded in the receiver, overcoming channel noise, yet still sending the encoded information via an analog FM wireless link.
Low Frequency Roll-Off
The low frequency roll-off can be set for a 3 dB down point at 35, 50 or 70 Hz to control low frequency rumble and ambient noise in the audio.
A DSP-controlled limiter is employed before the analog-to-digital converter. The limiter has a range of more than 30 dB for excellent overload protection. A dual release envelope makes the limiter acoustically transparent while maintaining low distortion.
The HM transmitter is powered by two AA batteries, yet still maintains long battery life, even with 48V Phantom Power engaged; up to 12.75 hours with Lithium batteries.
