The silver RDL DS-HA1A Stereo Headphone Amplifier Silverfrom RDL DS-HA1A Stereo Headphone Amplifier Silveris a two pair receiver and audio headphone amplifier compatible with RDL Format-A twisted pair products. Each unit receives stereo audio and 24 VDC power through a rear-panel RJ45 jack fed from a Format-A sender. The left and right audio signals received on pairs B and C of the twisted pair cable are amplified and fed to the left and right channels of the output 3.5mm mini-jack.

The front panel provides the headphone output jack and a single-turn user volume control. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. The audio input circuits feature very high common mode rejection and a high quality stereo headphone amplifier for superior audio fidelity and low-noise performance.

The amplifier is equipped with two Format-A RJ45 jacks. Either jack may be used as the input. The other RJ45 may be used to connect an additional amplifier or other Format-A receiver. Installation is simple and economical. A standard twisted pair cable is used to connect a Format A sender to the amplifier.

The unit features automatic fused power, hum rejection, low noise, and low distortion for designers and installers looking to work with twisted pair products. The DS-HA1A is ideally suited to guest room installations with bedside and restroom listening stations. The input is fully compatible with all RDL Format-A senders

Related Questions and Answers

Q: 1. Can I connect this to 2 bookshelf speakers (KD-51M) and my computer with a 3.5mm to RCA cable?

A: The Pyle Pro PTA4 Mini 2 x 120 Watt Stereo Power Amplifier w/ AUX/CD Input (BH # PYPTA4) will connect to most computers with a 3.5mm audio output via an RCA "Y" cable: Comprehensive 10' Stereo 3.5mm Male to Dual RCA Male Y-Cable (B&H # COMPS2PP10ST): https://bhpho.to/4a7ArnO

Q: 2. will this work with the mb-700 mic? also will this act as a phantom power source

A: The Sabrent AU-EMAC USB External Stereo Sound Adapter (Silver) B&H # SAAUEMAC does not provide Phantom Power, therefore, it would not work with any microphone that requires Phantom Power. You would need something like this which can provide phantom power: https://bhpho.to/2TIwkfr

Q: 3. Does the Roland Street EX come with phantom power switch for mics that need it?

A: No, it does not supply Phantom Power.

Q: 4. What is the output ohms for the speakers?

A: its 4-8ohms

Q: 5. Bass +__?__ dB / Treble +__?__ dB How many dB boost for the tone controls. Bass +10dB, +12dB, +15dB or what.?? WE need to know.

A: Sorry but can't help you. Mine broke within a year after I bought it. I had to go back to using my 25-year Radio Shack amp which still works same as when new.

Q: 6. can these two channels be bridged?

A: to the best of my knowledge, no. Basic 2 channel amp, but it does what it is supposed to do well with low distortion and dependable output levels. I used it for wired speakers on my patio, Bose, that are not that efficient, but it drives them well and cleanly. Hope this helps.

Q: 7. How to troubleshoot a PYLE PTA4 amplifier, when i turn it on the blue LED just blink and gone though power indicator stay on?

A: Please contact the manufacturer directly for service under warranty:Pyle ProTel: 800-444-5671Email: support@a href= http://pyleaudio.com target= _blank pyleaudio.com/aWebsite: a href= http://www.pyleaudio.com/ target= _blank http://www.pyleaudio.com//a

Q: 8. I am looking at the Yamaha amplifier AS 30l to upgrade my old system. I have Bang & O Danish speakers with free wires at the end of each cable. I see no place for free wires on this amplifier or the Yamaha AS500. It looks like I need the RCA Male Stereo Audio cable end pieces. If this is correct, would you let me know please. All of this is for a 32 inch Smart TV which is the largest size which will fit the space. The picture is great, but the sound options are driving my audiophile ears crazy. I do see a way to get the TV audio into the amplifier and that is by the digital audio output (optical), but no such place appears on the Yamaha AS500. There is a single audio output hole on the back of the TV, but that is beyond my ancient experience. I dont see an audio input on the amplifier of one hole. Am I wrong?My laptop enlarged image of the back of the amplifier leaves a lot to be desired. You will be happy to know that there is no problem with my Sony CD/DVD player which was purchased from you. I will also use my B & O turntable and be able to play my vinyl records again. As I said, we are talking older or ancient!

A: This receiver offers binding posts that will accept bare wire speaker leads.

Q: 9. I have an existing set of speakers going to my pool deck (Ch.2), and a set at the pool house (Ch.1). I'm looking to amplify the ones on the deck (Ch.2) so I have a balanced volume. Can I connect the existing speaker output (Ch.2) speaker to the input AUX. of this amplifier then run the speaker output from the amp to the pool deck and boost the volume?

A: Adjust the balance control.

Q: 10. Is the van speed variable and quiet at low speed.

A: The fan is fairly quiet...it speeds up to cool down as needed depending on output of power being used.

[RDL TP Format-A] I went from wireless to the HP2. It's going to be an adjustment being tethered, but this unit has tons of clean power. Getting to the battery compartment requires you to take off the belt clip. If your battery goes out during a gig, a quick replacement would probably be difficult. But great unit overall. 5

James	14/07/2024
[RDL TP Format-A] This is an incredible DAC, which also is a pre-amplifier with a headphone amplifier. The only thing I miss is the balance control, but that's OK. Easier better than my other two DACs. 5

[24 VDC @ 20 mA] I bought this item for a use slightly different than the manufacturer's intent - I gave to my boom operator as monitor. I fed him boom on one channel and the mix on the other so her could use the fade feature to select what he was hearing. The sound quality is really good, the construction is durable and the size is convenient. We powered the unit with a 9v battery and it lasted nearly two 12-hour days. That's impressive. 5

[0.4 lb] I own a great semi pro studio, and installed this amp last week. It sounds great. Drives 6 sets of headphones without any problems. The aux ins on each channel take care of any more me mixes. Do yourself a favor...get one. 5

[24 VDC @ 20 mA] I bought this system as a gift for someone but haven't actually used it yet, although it seems really well built and designed, like most Presonus products. What I'm most impressed with however is B&H getting it to me the day before Christmas when I only ordered it the day before. Hard to believe they actually got it done... I'll continue to buy from both B&H and Presonus. 5

[24 VDC @ 20 mA] If you are looking for a high quality build with powerful headphone amp, which can plug in anywhere on the Dante network, look no further. I love this thing! Another valuable feature is having both 1/8in & 1/4in jacks built in. 5

David	27/04/2024
[RDL TP Format-A] A quality headphone amp after my trusty Stewart died after 30 years. Lots of options for inputs and chaining these together. 5

Look Communications, Inc.	18/04/2024
[24 VDC @ 20 mA] Best solution for boardroom projectors. Nice and powerful given the footprint. Good full range sound. Has an imbedded condenser that causes a little hiss, back off the gains and increase volume with the source equipment. 5

Steve	09/04/2024
[24 VDC @ 20 mA] Not much to say. Plug it in and patch it in Dante. 5

John	30/11/-0001
[24 VDC @ 20 mA] Very sturdy box and belt clip. Knobs have a nice feel and comfortable resistance to them. Lasts over 10 hours on one battery. Stereo mini XLR to two female XLR Y-cable makes it MUCH lighter on the hip. (Competition has two XLR inputs (L/R) makes this heavy on the belt due to the pull of two cables.) Costs more than P1 but, when you consider PreSonus includes the the power supply and XLR, you wind up spending the same. I have three in my studio. Adding more soon. 5
