The stainless steel RDL 3.5W Stainless Steel Audio Amplifierfrom RDL 3.5W Stainless Steel Audio Amplifierfeatures one line input, an amplified output to drive a 4 or 8Ω speaker and a separate headphone amplifier. It features a balanced line level input that may be connected unbalanced. The gain range accommodates standard unbalanced levels as well as professional balanced levels. Its amplified output levels are controlled by a front-panel volume control. This amplifier features a mini-jack headphone output on the front panel. When a headset is plugged in, the power amplifier may be switched off. The two recessed slide switches located on the top of the rear enclosure are set prior to mounting the module. One switch is provided for setting the input sensitivity. The mute switch determines whether the power amplifier operates when headphones are plugged in.

Amplification for the speaker output is provided by a high-efficiency Class D power stage with audio filtering tailored for crisp, pleasant audio clarity. The high-efficiency Class D output stage produces negligible heat for all levels of expected voice or music modulation. Furthermore, the amplifier is designed to be mounted in a wall box. Its front panel does not include any illuminated indicators, making it suitable for installation in dark rooms or areas. The wiring is connected through a rear-panel detachable terminal block and module operation is from a 24 VDC ground-referenced power supply.

Related Questions and Answers

Q: 1. Does it include reel?

A: No, it does not include a reel I would highly recommend the Hewes stainless steel reels. They are more expensive, but most of the others on the market are only a half-step above junk.

Q: 2. Would this be good to split audio for a press conference?

A: The RDL RU-ADA4D is designed for permanent installation, and meant to be hardwired for audio distribution in media rooms, press conferences where audio jacks are preinstalled into the walls. For field use you may want to take a look at a Press Box. a href= http://bhpho.to/16GrjXQ target= _blank http://bhpho.to/16GrjXQ/a

Q: 3. Does DS-BT1A Wall Monted work with Dante and company like Bose, Yamaha or others?

A: The RDL DS-BT1A Wall-Mounted Bluetooth Audio Format-A Interface is not compatible with Dante.

Q: 4. Can the cross bar / boom arm be set to a 90 degree angle? I would like to be able to use it to do some top down photography.

A: The boom arm on the Neewer Stainless Steel C-Stand with Casters and Boom Arm (10') BH #NE66600099 can be set to a 90 degree angle.

Q: 5. Does it comes with power supply?

A: No, it does not. You will need the RDL PS-24AS.

Q: 6. this amplifier is 110 or 220v ?

A: The RDL RU-MLD4 - 1x4 Mic/Line Distribution Amplifier does require a 110 or 220V power source but rather uses a 24 to 33 VDC @ 80mA source via terminal block wiring or optional power supply. The RDL PS-24AS Switching Power Supply (BH #RDPS24AS) is available as a separate item for use with the RU-MLD4 and specifies compatibility with source connections between 100-240VAC: https://bhpho.to/39KBnoY

Q: 7. Please advise the item have stock available now?We looking for 8 pcs.

A: Please email us at sales@a href= http://bhphoto.com target= _blank bhphoto.com/a for assistance with your inquiry.

Q: 8. Need a low cost leveler for FCC Part 15 FM transmitter because input levels are not even. Will this work and how is frequency response affected?

A: This will help level the microphone audio. It will boost low levels and attenuate highs. It shouldn't affect audio frequency response for speech range.

Q: 9. Are the outputs isolated from inputs and are all the outputs isolated from each other?

A: Yes

Q: 10. Can this be used to amplify a signal over a long speaker cable? I have a 5.1 system installed, but since the left front and left back speakers have longer wires, their signal is lower. My system allows me to boost the signal to these speakers, but it's not enough. I need more signal to these two speakers.

A: The RDL ST-PA6 is designed to connect from a line level device. It is not able to be used in line with speaker level input and output.

Gives an accurate reading quickly and efficiently. Recommend it. 5

Brent	13/09/2024
This item worked as expected. It was purchased to amp a line level signal going into an amp. Just make sure you purchase the power supply as well. It is sold separately from the device itself. 5

Nice and simple DA that works well for balanced signals. Wish it came with it's own PSU but eh. 5

Franklin	11/08/2024
Great quality thermometer, it is stainless steel, great build. It measures temperature very quickly, no need to wait for a long time before the needle moves. Highly recommended for developing film using a tank. 5

Hino	03/08/2024
Does the job for me! 5

very durable w/perfect fit 5

Immoe	11/07/2024
I use this to get the temperature to process C-41 film. It developed the film pretty good so I'm guessing this is accurate. Easy to use, although I don't like using the handle it comes with because it just gets in the way. 5
