Offering uncompromising audio detail and the lowest possible noise, the Purity Stereo Headphone Amplifier from DACS Audio builds upon the technical innovations of the HeadLite and +Power modules to get the most out of audiophile headphones. With a Pure Class-A output circuit and loads of transient headroom, the Purity headphone amp will make any headphones shine, revealing the true details of your audio content.

DACS Audio achieves this high level of performance with their unique Purity BDZ power supply, which drains excess voltage and EMF for an output impedance of zero ohms. The balanced XLR-1/4" combo inputs are interference-free, while the balanced XLR 4-pin headphone output sports extremely low crosstalk for the best possible listening experience. Unbalanced RCA inputs and a stereo 1/4" headphone output are also provided for extra connection options. This headphone amp includes a power cable.

Listening tests with a large mix of headphones confirm DACS' Pure Class-A topology excels with all types of headphones and listening levels. To run in Class-A, the Purity Headphone Amplifier and Purity BDZ Power Supply generate a lot of heat. The case and ultraquiet Noctua fan provide plenty of airflow to keep the temperature stable, whatever the load.

DACS’ balanced input uses an instrumentation format, with hand trimmed CMRR to give the most accurate interference free signal.

Then DACS looked at balanced headphones. The Purity Headphone Amplifier provides remarkably low crosstalk between the two independent amplifier channels; using balanced output connections. That channel independence is maintained without compromise from the Purity BDZ Power Supply all the way to the ears.

The new Purity BDZ Power Supply uses a superstable, superlow noise op-amp-based design, with zero-ohm output impedance. When driven hard, headphones produce back EMF generated by current flowing back toward the voltage regulator, causing instability. In conventional PSU designs, this back EMF significantly reduces the PSU’s performance, with the amplifier losing control of the headphones and generating distortion. DACS’ unique Purity BDZ Power Supply design sinks that current away ensuring zero-ohm impedance and total output voltage stability, regardless of what's happening at the headphone level.

Related Questions and Answers

Q: 1. Is there a way to set a password so others can't connect to it?

A: The short answer is no, The unit is a receiver only, and is always ready to pair when not already paired. While DN-200BR is paired with a Bluetooth device, other Bluetooth devices cannot pair to it. You must unpair (disconnect) the current Bluetooth device from DN-200BR to make it available to others. If it is a\already paired, and both devices are always on, nothing else will be able to pair to it.

Q: 2. switchable to 240 volt for worldwide use?

A: Thank you for your question. This amplifier has a 120/240 volt switchable power supply.

Q: 3. What is the range of this device?

A: I use this in a open gym and we get about 70 Feet no problem.

Q: 4. I want to understand pairing with this. Most Bluetooth devices can have multiple devices paired to it and some allow multiple devices to be connected and some only one to be connected. But even the ones that only allow one device to be connected allow multiple to be paired. So, if 1 and 2 are paired, then 2 can't connect while 1 is connected but it can connect as soon as 1 disconnects. If I am reading this correctly only one device can be paired. So for 2 to connect, 1 would have to disconnect and unpair and then 2 would have to pair and connect. Then for 1 to reconnect, 2 would have to disconnect and unpair, 1 would have to pair and then connect. Do I have this correct?

A: You've got it.

Q: 5. Baass sound good?

A: Yes, it captures low frequency sound very well, very accurately, without being overwhelming. I record at music venues, and it captures the bass just like being in the room.

Q: 6. according to the product highlights this amplifier Gli pro PVX9000 switchable from 110 to 220 Volt, is that true? pls confirmed so i can place my order. ...thank u

A: That's what is says. Gli pro PVX9000 features a switchable 115V 60 Hz/230 V 50 Hz power supply.

Q: 7. Will this product function with wireless Bose headsets from Marshall Amps?

A: No

Q: 8. I see the outputs are stereo L&R. I only have one available channel strip on my mixer. Will a “Y” cable work to sum both L&R to a mono input to my mixer?

A: You should use a device that sums stereo to mono (a Y-cable is good for splitting audio, but not for combining it). A Radial Engineering StageBug SB-2 would be good for this, using a dual-1/4" unbalanced cable. It would give you an XLR output for your mixer.

Q: 9. Does this device work when the air temperature is over 90 degrees, like an outdoor concert in the summer?

A: The recommended operating temperature for the Denon DN-200BR Stereo Bluetooth Audio Receiver is 41 to 95°F. It is not recommended for use when the environmental temperature is above 95°F or below 41°F.

Q: 10. I bought this mic years ago and used it with mini plug and batteries. If I get the XLR to 5 pin, can it be used powered by the camera? I have a Canon XF400

A: Absolutely
