The Lectrosonics UHF Filter Amplifier Module Block 23-24provides a unique, high performance solution for antenna systems requiring long cable runs or distribution to multiple receivers or locations. The unit can be used to apply RF gain at the antenna ahead of a long run of coaxial cable to compensate for signal loss through the cable. A compact, high performance multicoupler can also be configured using the UFM50 ahead of an RF splitter to offset the loss through the splitter.

The UFM50 design places RF filtering before gain to minimize intermodulation (IM) products and prevent overload. Two transmission line ceramic resonators at the input provide filtering with a 50 MHz bandwidth. Following the filters, 12dB of gain is applied with a high quality GasFET RF amplifier with an excellent +41dBm IP3. The result is outstanding RF performance without IM or overload problems.

A switching regulator is used in the power supply to control current consumption over an input voltage range of 8-16 volts. The regulator maintains low current consumption and low heat dissipation which is especially useful in portable audio mixing common in field production and ENG.

The UFM50 can be powered from external DC or via phantom power through a coaxial cable connected to a multicoupler. The housing is constructed of cast aluminum with a brushed aluminum cover plate. Two rugged BNC connectors and a threaded, locking power jack provide secure connections for rugged field conditions and for long-term installations.

Related Questions and Answers

Q: 1. how many receivers can I use with one transmitter?

A: There is no limit to the amount of receivers usable with The Lectrosonics IFBT4 transmitter.

Q: 2. We have 2 sets of these and would like to use each set independently. Currently if you talk on one it can hear on both. how can we set them?

A: The PKT-23 is a multi-channel transceiver. In order for 2 sets to be used independently, two of the units will have to be assigned to a different channel. Channel setting instructions are listed in the operation manual. Please see the following link: http://bit.ly/1R5W5dK

Q: 3. Are these radios good for indoor as well as outdoor use?

A: Yes. You are able to use these both outdoor and indoor. Operating conditions:Open areas without obstructions is up to 5 miles (8 km)Residential areas near buildings is up to 1.5 miles (2.4 km)In steel and/or concrete reinforced buildings the range is up to 225,000 sq.ft (20,900 sq.m)The range in high-rise buildings is up to 17 floors

Q: 4. what is the matching reciever?

A: The Lectrosonics SMQV Super Miniature Wireless Microphone Transmitter is compatible with any Lectrosonics Digital Hybrid receiver in the correct frequency block, such as BH #LEUCR411A21.

Q: 5. what is the smqv connector? is TA3M? or TA5M?

A: The connector is a TA5.

Q: 6. Is there a 12'' version of this product? It can be a different brand as long as it is switronix compatible.

A: as long as i know no there is not

Q: 7. Can I power these from the Sound Devices SL-6?

A: First make sure you are using the UFM230L for the right reason. Why do you need it?If you really do need it, then here's the answer:From the SL-6 manual:Antenna Bias PowerIf needed, 12V bias power may be provided to each antenna.To supply bias power to an antenna:1. Press the MENU button to access the Main menu.2. Do one of the following:X Turn and press the Headphone encoder to select SL-6 Antenna A Power.X Turn and press the Headphone encoder to select SL-6 Antenna B Power.3. Turn and press the Headphone encoder to turn bias power on or off.

Q: 8. Are you able to hear incoming calls while around heavy equipment?

A: Yes, you will not have any connection issues when receiving calls around heavy machinery. If you are asking about if the ringer is loud enough for heavy industrial environments, that depends on the ambient noise level of the area.

Q: 9. Is there a vibrate feature?

A: No, you are alerted to an incoming call by a bell tone and flashing light.

Q: 10. Maybe I'm an idiot. Trying to update some older Lectrosonic gear. This states for "Transmitter and Receiver" Is this a multiuse antenna?

A: You can either use the Lectrosonics AMM-24 antenna on a Lectrosonics Block 24: 614 to 639 MHz receiver, or you can use it on a transmitter.

[Block 23-24] Lectrosonics claims that their products are made by fanatics and I believe them. Outstanding performance and range that eclipse the bargain brands. Wide range of frequencies available and very easy to scan locally for clear freqencies. lectrosonics service (for a fee) can also re-block your frequency group unlike other brands. 5

[Block 23-24] I do production sound for a varity of different types of projects from feature films, to 1 day commercial shoots. I use these in the field everyday. They are low energy consumption and I typically only have to change batteries twice in a 10-14 hour day. (I power them down during lunch and any time we have a long set up.) I have never experiences any rf cutting like on the 100 series or other brands of lavs. 9.8 out of 10!!! 5

[Block 23-24] Great product, decouples the amps from the floor, it is truly amazing! 5

[Block 23-24] These little transmitters from Lectrosonics do so much in tiny package. great range, no drop outs or interference issues. Being so small they are easy to hide on tight and challenging wardrobe. They can be controlled using the lectro Rm iPhone app which means the only time you need to physically retrieve the pack from talent during a performance is to change the battery- which you will do less often due to the fact you can put the Tx to sleep when the talent is off the set and wake it up again when needed using the afore mentioned app. 5

[Block 23-24] For all true professionals in the sound biz, this is for you! 5

[Block 23-24] I thought the level of expertise, the overall knowledge experience of the customer help was outstanding. Both the gentleman I spoke to were extremely polite and courteous, keeping me informed of the movements of my order. 5

[Block 23-24] Solid and well built and protected hma in a day of heavy heavy rain. 5

James C.	07/06/2024
[Block 23-24] The price tag is a bit overwhelming when you've never used one of these guys. But once you do you'll never turn back. Quality is at the utmost and the RF strength is second to none. I never have to worry about losing a signal mid-take and they can be easily hidden with neopaks. Highly recommended. 5

[Block 23-24] I was seriously about 400ft away and the clients were still able to hear the mix clearly! Love this awesome device! My only complaint would be the antenna being on the bottom. It made securely placing it in my K-Tek Stingray Large Audio Bag a bit challenging as I have 5 other receivers in there with XLR cables and Remote Audio BDS Power cables attached to them. Have yet to get the Sound Devices SL-6 attachment for my Sound Devices 688. 5
