The black RDL DB-HA1A Stereo Headphone Amplifier Blackfrom RDL DB-HA1A Stereo Headphone Amplifier Blackis 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 DB-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. What country does the power plug work in?

A: USA/North America.

Q: 2. Can I connect my nextbook for better sound?

A: You can hook up any audio source with an auxillary cord. I've used phones, iPads, and IPods without an issue so I'm assuming your Nextbook would be similar.

Q: 3. Pyle Pro PTA4 Mini 2 x 120 Watt Stereo Power Amplifier w/ AUX/CD Input B&H # PYPTA4 MFR # PTA4. CAN YOU TELL ME IS THIS A 4 OR 8 OHM AMP?

A: It is 4 ohm, but can work with 8 ohm equipment, if you believe the short manual they provide.

Q: 4. would this help old turntable without preamp for use with speakers with phono hookups on the main speaker i use old 70's realistic turntables without preamp and won't work with the new speakers i recently purchased

A: Definitely. I love mine.

Q: 5. PTAU45 - What is the frequency response of this amp?

A: the frequency response, as listed in the owner's manual, is 20Hz-20kHz

Q: 6. Can the USB port be used for a Bluetooth USB adapter to stream audio?

A: No, the USB port on the Pyle Pro PTAU45 Mini Stereo Power Amplifier cannot be used to connect a Bluetooth USB adapter, however, you can use a Bluetooth adapter with a standard analog audio plug to connect to the RCA aux inputs or the 3.5mm CD/MP3 input. The Aluratek iStream DockFree Bluetooth Audio Receiver (B&H # ALAIS01F) could be a good option for a Bluetooth adapter. It has a 3.5mm plug and comes with an RCA adapter.

Q: 7. Does this work for both moving coil or moving magnet phonos?

A: Unfortunately the manufacturer does not specify which cartridges are recommended, however we would recommend this unit for use with MM cartridges for best results.

Q: 8. What kind of mic do i need to use with this amp?

A: Use a dynamic type microphone: Example: Audio-Technica ATR1200 Cardioid Handheld Dynamic Microphone B&H # AUATR1200

Q: 9. Is this amplifier bridgable?

A: No, this amplifier is not bridgeable. Bridgeable amps have specifically designed electronics for bridging purposes. This isn't one of them.

Q: 10. Does the Roland Street EX come with phantom power switch for mics that need it?

A: No, it does not supply Phantom Power.

[0.5 lb] 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

[0.5 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 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

[24 VDC @ 20 mA] I've only used it for a week and am very impressed. Great sound and great hardware quality. Also a great value. 5

[0.5 lb] I was using the Behringer PowerPlay Pro 4 channel headphone amp but it had a hum in it. Even lifting the ground did't help. I had used Art equipment before and was very pleased with their quality and price so I bought the rackmount HeadAmp6. It is extremely quiet. This is a great amp. 5

[0.5 lb] I needed to split an audio monitor line to three different headphones and this works perfectly for that application. Great price & super fast shipping, too. 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

[0.5 lb] I’m happy with amp and I like it in the color black better than the older white model. Great piece of equipment for only $25 5

[24 VDC @ 20 mA] Works great for my broadcast application. 5

[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
