The HamiltonBuhl ALS700 Assistive Listening System helps audiences hear audio more clearly—at a comfortable amplification level and even over background sound.

The system includes a single transmitter with both microphone and line inputs, along with six receivers, each with a mono earbud. The listener simply holds the receiver or uses the belt clip to attach it to clothing and wears the connected earbud. Audio from the transmitter is heard clearly and intelligibly, and each receiver has an independent volume control so listeners can find a comfortable level. The easy-to-use system is well suited for a wide variety of applications in schools, theaters, and houses of worship, as well as entertainment and cultural attractions.

A single ALS700 system transmitter can serve an unlimited number of receivers in a 150' range so you can add more transmitters as your needs grow. Fully ADA compliant, each ALS700 system includes one transmitter, six receivers, six earbuds, and a carry case

Related Questions and Answers

Q: 1. Can it have interference with wireless microphones?

A: Yes, it should work just fine.

Q: 2. Is there a "gang" charger for the receivers or do individual chargers need to be purchased when used with rechargeable batteries?

A: Yes there is a Williams Sound CHG3512 - 12-Bay Body-Pack Charger B&H # WICHG3512 available for the Williams Sound PPA R37 N Select Channel FM Receiver (No Earphone/Batteries) B&H # WIPPAR37N.

Q: 3. hi, please let me know if this could deliver live voice to the headphones?

A: Yes, we use it for our Sunday service. The only difficulty is that the sound is sometimes fuzzy and sometimes the older folk need assistance figuring out how to use them and it disrupts things a bit to have others help them in the middle of the service.

Q: 4. Hi, I thought only the transmitter (W900-BLTM) in the LCP/12/901BT package provides microphone input, and the transmitter (W900-Multi) in this package does not have microphone input. Is it correct?And how do the headphones get charged? Many thanks!

A: Hi, I know that on the system we have there is a microphone input in the transmitter. It is an 1/8 jack insert. The headphones have a DC charger with multiple plug ends that charge several (if not all) of the headsets at the same time. Hope this helps!

Q: 5. Can I connect an iPhone and see the image using WiFi?

Q: 7. Can I connect to PC and making live streaming through it?

A: If you want to live stream with this you would still need a video capture card from the receiver to your PC.

Q: 8. What are the distance to the headphones that transmitter works?

A: I currently have my headphones installed approximately 10-12' from the transmitter and they work great. I have also tried them in our office spaces and they work okay with just a bit of interference. Our offices are down a hall and through a door in relation to the transmitter (approximately 30' away).

Q: 9. How many of these stations would i need for a lecture hall of 100 seats? Can the same one be used for two lecture halls?

Q: 10. I have two mini wireless speakers, can this transmitter be used to connect my stereo to the speakers?

A: I don't believe so. It is designed to work with their headphones. It transmits on 4 different frequencies, but they are only designated by color, not actual frequency.

[<0.5%] These receivers work well for hearing in the ear or plugging into a car radio port to transmit the sound of a service. They are extremely reliable and do a great job. The range is extremely far for receiving a signal. 5

David	05/09/2024
[41 dB] Headset is light weight, comfortable to wear and gives great volume for the hard of hearing. Works well for those with 2 hearing aids - take them out and use the headset to cover both ears. 5

[5.855 lb] I bought the ALS700 Assistive Listening System for our church. It comes with ear buds which are not the best for hearing assist for two reasons. cleanness and most of the users have hearing aids. the ALS700 Assistive Listening System is a mono device. It is hard to find mono head phones. I bought 6 of the ALSH700 Mono Personal Headset for the 6 receivers. Voice sound quality is good and so far they have been reliable. The price is very reasonable. So far every one in church that have used them likes them. 5

[5.855 lb] With the option of headsets and ear buds to use, this system meets the needs of each person. Great range. Easy setup. B&H had knowledgeable support to answer my one question. 5

[41 dB] These mono earbuds eliminate the need for a mono-to-stereo adapter (and a right-angle adapter) when I listen to my mono radio scanner. The earbuds have an (almost) 90 degree plug (different from what is shown in the photo). 5

[100 Hz to 8 kHz] This system is by far the best system for venues looking for an economical choice to offer hospitality to those with hearing loss. One of my parishioners, who has not really heard what has been going on in worship for years, said to me after his first time using this, You can't imagine the difference. I want to let potential buyers know that, for best results, you may need a separate amplifier to boost the level of audio going into the transmitter. It all depends on your setup. If you hook this up, and the sound is still not loud enough at full volume, insert an amplifier of some sort (am/fm stereo ) into the audio chain between your sound system and the transmitter input. I am using an old Realistic stereo. I am also using an audio compressor, between the amp and the transmitter, but that isn't necessary. I am using it primarily for its gate function, that eliminates some noise when no one is speaking. The compressor keeps the audio volume level. 5

[100 Hz to 8 kHz] We ordered 10 of these for our church for our assisted listening system. They work great! Awesome Quality. Will definitely be buying more in the future! 5

[>0.005%] Great sounding system when paired with the optional headphones, fabulous price and easy hookup. 5

Rodney	11/06/2024
[41 dB] Our church has a great PA system. Yet some members. Had a complaint that they cannot hear the message. With that comment we purchased the assisted listening system. First Sunday impression was they could hear the service that’s all I wanted to hear a great report. 5
