Williams Sound FM Receivers

FM Receivers: What’s the difference between the three William Sound receivers?

William Sound makes three receivers, the R37, the R38, and the R37-8. When it comes to the differences between these receivers, it all comes around to how you tune them. However, tuning them is not something to worry about since they usually are already set up after you buy them.

Generally speaking, most people will never have to actually change the channels. However, for some people who need to listen to multiple languages, this becomes vital since they will use multiple channels at the same time.

R37

If you do not need to change the channels or run multiple adjacent rooms, then you should probably stick with the R37. This one is the least expensive of them, and it works great for these occasions. If you do need to change the channel, you simply press the ‘channel seek’ button inside the battery compartment while your transmitter is switched on. It will find that transmitter, and it will stay on it. This receiver is very simple to operate, it has an on/off switch with volume control, and you plug in a headphone or earpiece on the top.

R38

R38 can select any one of up to eight channels that may all be running simultaneously. You change the channel by pressing the menu button once, and you press the arrow buttons to choose what channel you want to tune in to. When you need to change the channels often, R38 displays the eight channels with cardinal numbers (such as channel 1, channel 2, channel 3, etc.) and you simply select the channel you want to listen to. Additionally, this receiver has an LCD display where you can see specific information, such as the volume. This receiver is more complex, and if you need to do a lot of channel changing, it is ideal for that purpose.

R37-8

Finally, we have the R37-8, which is a hybrid model between the other two options. It has a dial on the top that goes from 1 to 8, so when you give these out to people, it is expected from the users to change the channel themselves. You tell them to tune to a channel, and they will just turn the knob to that specific channel. Next, they plug in a headphone and they should be ready to go.

The similarities

The similarities between these receivers include:

• They all run on AA batteries
• They all can be charged if you wanted to use NiMH rechargeable batteries
• They all have charging lugs to go in the William Sound charging trays
• They all will accept either a stereo or a mono headphone or earpiece

Facts

• Williams Sound makes 3 current models of Receiver: The R37, R37-8 and R38.
• The main difference between them is in how they tune to different channels. If you only plan to use 1 channel, the R37 will serve you well.
• To change the channel on the R37, you press a ‘Seek’ button inside the battery compartment.
• On the R37-8, you can select any 1 of 8 channels by turning a knob. If you have multiple transmitters and receivers, you can use up to all 8 channels at the same time in the same location.
• The R38 offers a choice of 17 channels by means of up and down tuning buttons and an LCD display. If you have multiple transmitters and receivers, you can use up to 8 channels at the same time in the same location.
• All 3 models feature digital tuning and digitally-synthesized sound.
• Buying bulk packs (10 or more receivers) should save you money, but Williams Sound does not allow us to publicly advertise lower prices for bulk packs. If you need more than 10 receivers, we highly recommend you call or email us before ordering.
• We generally do not include batteries when we sell receivers, because that would be a very expensive way for you to buy batteries!
• Williams Sound receivers are covered by a limited lifetime warranty. Headphones/earphones and other accessories are warrantied for 90 days.
