Univox DLS-50 and Univox AutoLoop Room Loop Systems

Univox DLS-50 and Univox AutoLoop: The home loop system that lets hard of hearing people clearly hear in groups, meetings and while listening to the TV or other audio sound systems—even in noisy places!

Combined with your telecoil-equipped hearing aids,
the Univox DLS-50 or Univox AutoLoop can help you hear
beautiful clear sound again!

Note: The Univox DLS-50 has replaced the Univox 2A

Note 3: If you have a new flat-screen TV that doesn't have the standard RCA audio output jacks, but instead has the new TOSLink-style optical sound jack or a digital coaxial audio output jack (typically orange-colored), then you will also need a digital to analog audio converter as loop amplifiers do not have coaxial or TOSLINK-style jacks.

DLS-50 Features

 
  • For portable or permanent installations. "It is very simple to disconnect and move to another location"
  • Easy to set up and operate "I had it up and running in less than 10 minutes"—happy blind customer
  • Has three lights—one to tell you the power is on, one to tell you there is a signal coming into the amplifier and the third light tells you the loop is working
  • Ideal for listening to the radio, TV or stereo without interfering noise no matter where you are in the room
  • Helps you hear in small groups and meetings
  • Adjustable bass, treble, power and mic gain controls
  • Small size—less than 6" wide x 3.5" deep x 1" high
  • Weighs only 9 oz

(rear view)

  • Has 2 inputs—one line input and one either line or microphone input. This way you can listen to two different devices at the same time—for example, listen to the TV and also hear a person conversing with you at the same time via a separate microphone
  • You can plug in either a room loop wire or the loop pad

Basic Univox DLS-50 or AutoLoop System only $189.00

  • The basic system includes the Univox DLS-50 or AutoLoop loop amplifier, A/C power adapter and audio patch cord.

    Note 1: In order to use a room loop (or loop pad) you must have hearing aids equipped with telecoils or use an induction loop receiver.

    Note 2: To use the Univox DLS-50 or AutoLoop in a motor vehicle, you need a power adapter (not included). Go to any Radio Shack store and get their 12 VDC 2A  Car Power Adapter with 8' cord—part no. 270-042 ($6.97).

Note 3: If you have a new flat-screen TV that doesn't have the standard RCA audio output jacks, but instead has the new TOSLink-style optical sound jack or a digital coaxial audio output jack (typically orange-colored), then you will also need a digital to analog audio converter as loop amplifiers do not have coaxial or TOSLink-style jacks.
 

Standard (PCM) left and right channel stereo DAC:

If your TV or Sound System uses 2-channel STEREO (Pulse Code Modulation [PCM]) audio, then the adapter you'll need is the Monoprice Digital to Audio Converter (or equivalent) for just $22.56 (includes 3' TOSLINK cable & wall power adapter). If you need the coaxial cable instead of the TOSLINK cable, just make a note in the directions box in the shopping cart and we'll substitute it.

Note: If you are so inclined, you can order this DAC from other sources on the Internet and save yourself a few bucks.

Click here to order the STEREO (PCM) Digital to Analog Converter for $22.56

Dolby 5.1 Surround Sound DAC:

If your TV or sound system uses Dolby 5.1 (or 7.1) SURROUND SOUND audio, then the above adapter won't work.

You have two basic options. First, check your TV's menu. Many, but not all new TVs allow you to select either standard stereo (Pulse Code Modulation [PCM]) or Dolby 5.1 Surround Sound for the audio output. If you are not using Surround Sound, then choose the PCM option.

If you are using a Surround Sound system, then set your TV to Dolby 5.1 Surround Sound and get this DAC that handles both PCM and Dolby 5.1 (and 7.1) Surround Sound for only $56.32 (includes 3' TOSLINK cable & wall power adapter). If you need the coaxial cable instead of the TOSLINK cable, just make a note in the directions box in the shopping cart and we'll substitute it.

Note: If you are so inclined, you can order this DAC from other sources on the Internet and save yourself a few bucks.

Digital to Analog Converter for $56.32

If you need an extra Toslink cable, you can order it/them here.

Click here to order a double male 6 ft. Toslink cable for $3.20.

For home use, either the Univox DLS-50 or the Univox AutoLoop are typically the models of choice. If you like to have control over the settings, choose the Univox DLS-50. If you'd rather just plug it in and let it automatically configure the settings so you don't have to worry about them, choose the Univox AutoLoop. To order, click on the model number of the loop amplifier you want to order.

Model Price Maximum Area Covered (in sq. ft) Max. length of
wire in loop (ft)*
Univox DLS-50 $189.00 540 90 - 100
Univox AutoLoop $189.00 540 90 - 100

* The maximum length of wire in the loop varies depending whether the room is a square (1st number) or a long rectangle (2nd number). This gives you an idea of approximately how much wire you might need depending on the room shape. The important things are the shape of the room and the amount of metal near the loop wire rather than the number of square feet the loop encompasses or the actual length of the loop wire.
 

Installation Guides

 

If you are installing a loop system in a public place, here are a couple of signs you can print indicating that an audio loop system is installed.

 

Car Power Adapter:

If you want to use your Univox DLS-50 or AutoLoop in a car or motor home, you need the 12 volt car power adapter. You can either get this yourself at Radio Shack (Part No. 270-042) or click here to order the car power adapter for $12.00.

 


Output Devices:

In addition to the basic system, you will also need an output loop of some kind. (The basic system does not include an output loop.)

You have two choices:
 

1. Loop Pad

The loop pad is the easiest way to loop your favorite chair—just place it under the chair or under the cushion. It has a 32 foot cord so it will reach just about anywhere you want it to. The Loop Pad is also ideal for looping your car—just place it under your car seat. Note: the Loop Pad does not work by itself—it needs to be plugged into the special jack in the back of the Univox DLS-50 amplifier.

The Loop Pad measures 15.75" x 15.75" and comes with a 32 foot (10 m) cord. $40.95.

Click here to order a
Loop Pad

Loop Pad "Y" Adapter

If there are two hard of hearing people in the household and you both want to hear the TV, etc. via Loop Pads, plug this "Y" adapter into the Univox Loop Pad socket and then you can plug 2 Loop Pads into it.

Click here to order the Univox Loop Pad "Y" adapter. $29.95.

Loop Pad Extension Cord

If the 32' cord that comes with the Loop Pad is not long enough, the Loop Pad Extension cord will give you another 32' (10 m) of cord to fit even the largest room in your house. It plugs into the special Loop Pad plug on the back of the DLS-50 loop amplifier. The Loop Pad cord plugs into it.

Click here to order the Loop Pad Extension Cord. $14.00.


2. Room Loop

The basic system does not include the insulated wire for a room loop. If you are hooking up the Univox DLS-50, use either 18, 20 or 22 gauge stranded wire.

The maximum perimeter you can loop with the DLS-50 loop amplifier is about 100 feet (depending on the room shape). You can use either a single wire loop or a double loop. Normally the single-wire loop provides a good signal.

If you are installing a single wire loop for the DLS-50, you can order 100 feet of 22 gauge loop wire (right) for $11.99. You have your choice of either black or white.

If you want to install a double wire loop, you can get 18 gauge speaker wire from Radio Shack (Part No. 278-1104 $19.79 for 100 feet (30 m) or Part No. 278-008 $12.19 for 60 feet (18 m), 75' of 20 gauge speaker wire for $12.19 (Part No. 278-1388), or 100' of 22 gauge speaker wire for $12.19 (Part No. 278-1385).

Input Devices:

In addition to the basic system, you will also need an input device of some kind.

You have two choices:
 

1. Microphone Input
 
If you want to use the Univox DLS-50 loop system to listen to people live, you will need a microphone to input the sound into the loop system. Almost any microphone with a 1/8" (3.5 mm) plug will work. My preference is a lapel microphone that clips to your clothes just below your chin. This will give beautiful clear sound and is hands-free, but you are tethered to the loop amplifier by the length of the microphone cord. (Note: Microphones with either stereo and mono plugs will work in the dedicated MIC jack (right plug), but only microphones with a stereo plug will work in the Mic/Line (middle) plug.)
Lapel Microphone for the Univox DLS-50—$66.00

This lapel microphone works well with the Univox DLS-50. It has a 42" cord.

Mono Extension Cord—(12' cord) (WCA 007) $12.00

If you need a longer microphone cord so you can more around freely, this 12' mono extension cord works well with the above microphone.

 Click here to order WCA 007

 

If you want to use a microphone to pick up the sound directly from the device's speakers (for example, from a TV with no audio outputs, or from the speakers in your car), you can use this great little round microphone (MIC 13A) that fastens to the front of the speaker by Velcro. Put the Velcro on the mic side (as shown) so it faces the speaker. That way it will pick up the sound from the speaker and not all the surrounding sounds. The mic cord is 6' long. Order this microphone for just $29.00.

To give the speaker complete freedom to move up to 200 feet away, instead of using a hard-wired microphone, you can purchase Radio Shack's FM Wireless Microphone system (Part No. 32-1258 $79.99) and connect it to the Univox DLS-50 amplifier via a patch cord (Part No. 42-2433 $5.99). Since this patch cord has a mono plug and the Univox jack is stereo, use an adapter (Part No. 274-374 $2.99) between the Univox and the patch cord.
2. Direct Input

If you are hooking your loop system into your TV, VCR, radio or stereo, as long as these devices have standard audio outputs (RCA jacks), you do not need to buy anything else. Use the included audio patch cord.

  • Comes with a quick disconnect neck strap for your convenience. Just wear it around your neck and forget it's there
  • Has both volume and tone controls
  • A green testing light at the top front indicates you are inside a working loop of good signal strength. A yellow light indicates the loop strength is "workable", and a white light (no light) indicates the loop is not working or is too weak to use.
  • A blinking red light below the speaker indicates the unit is on and the batteries are working.
  • Uses two AAA batteries. Lasts 100-300 hours depending on use.
  • To use as a loop receiver, plug your favorite earphones or earbuds (not included) into the Univox Listener. To use as a loop tester, you can use your earbuds or listen on the built-in speaker.

"I am really sold on the Univox 2A  [now Univox DLS-50] and would definitely recommend it as the first choice for anyone interested in obtaining a loop amplifier for home or portable use."— D. Bishop

"Thank you very much for prompt delivery of your Univox 2A room loop system to me which I received this afternoon. I have already hooked this system to my TV without any problems, and it worked wonderfully."—H. H.

"I want to tell you my experience with the Univox 2A. My wife has exceptionally good hearing and in the past, we always had a problem. Either the TV sound was too low for me, or too loud for her. Sometimes it really caused some rather heated discussions. Last night was the first trial of the Univox 2A. I can't tell you how happy we both are! So thanks to the Univox, we don't see any more problems for us."—E. B.

"The Univox 2A arrived today and after quickly setting it up, I was completely amazed at how beautifully it worked. My wife is delighted, has stopped using ear plugs ( because of our loud TV), and thinks we can make it through another 59 years."—A. G.

"I am happy to tell you my husband went to my dads and got the Univox 2A all hooked up right. It works perfect! Daddy is so pleased. It is nice to know he can enjoy the news and his favorite shows now."—R. W.

"I read the reviews of other users of the Univox 2A and I was still a little apprehensive. Well, I just hooked it up and I am blown away. Sound is piping through my hearing aid (with the t coil program on) and I can hear every word, even the commercials, which previously were impossible. This is truly truly one of the happiest moments I have had in many years!"—M. H.

A church installed a new loop system using the large Univox PLS-700 loop amplifier. The first Sunday it was operational, a hard of hearing man stood up and told the congregation, "Today for the first time in 30 years I was able to hear everything that was said. It's wonderful!"—Bob R.

After they installed a loop system in their church, a pastor wrote, "Last night we showed the Jesus film for Good Friday and J____ came up to me crying. She said, 'That was the first film I have ever heard in my life.' Wow, was it ever worth it to see and hear that."—J. S.
