Dec 28,  · I bought the headphone amp Presonus HP4. Sound is very good (I hear no difference in blind test with Lake People G100), loud with low impedance headphone and a little quiet with my AKG 240 DF but I noticed that the volume have no effect from 12 o'clock position - only first half affects on

Recommended earphone impedance: 32 - 600 ohms; Balanced line input: 6.3 mm jack, L/R Comparing same headphones (DT990Pro) with the HP4 output to the headphones output of the Audient iD14, one can surely feel a difference in volume, even though I do not need it. buying Presonus HP4 is a very good deal in my opinion. handling. features

Portable and compact, it offers two XLR line-level inputs and one stereo 1/8-inch headphone output with volume control and can be powered by a 9V battery or a DC power supply. Operation can be switched between stereo and mono, and a Pan knob is provided. A 2m audio cable is included.

Headphone Impedance Working Range: 32Ω - 600Ω We were too, so PreSonus created the HP4 headphone-distribution system. These headphone amps are louder than you're ever likely to need for session and stage use, so be careful with that level control. Yet the sound is clear and clean, with a wide dynamic range.

Are you and your session players and bandmates tired of straining to hear underpowered headphones? We were too. That’s why Jim Odom and his jambalaya-fueled team of engineers designed 150 mW headphone amps for the HP4 headphone-distribution system. These headphone amps are not just loud enough for session and stage use

The PreSonus HP4 perfectly answers the need for a headphone distribution amplifier while having professional specs in a small package at an extremely affordable price.

The hd6xx series seems to prefer an output impedance of around 50ohm (see critical dampening)) The hp4 power supply is also +/- 15v internally, hence you can probably swap that ac adapter between l30 and hp4. Internally the amp is very

It turned out to be the headphone amp. 3. The 51 ohm impedance won't properly drive some lower-impedance headphones, such as Audio Technica M50 (35 ohms), or

The HP4 says the Balanced TRS output is 51 ohms. I don't think that means the headphone jack impedance is 51 ohms. I think that is for the jacks 

The PreSonus HP4 ensures that they get plenty of volume in their headphones. Four discrete amplifiers allow you to route monitor mixes to up to four performers. output impedance of headphone jacks: 51 ohms; headphone impedance range: 32-600 ohms; includes AC power supply; 5-1/2"W x 1-3/4" H x 5-1/2"D; weight: 5 lbs. warranty: 1 year; Our 60

May 20,  · I can't find any information beyond the 150 mW / 60 ohm load on the headphone outputs of the V2. This is a bit more than the Studio 68 which has an impedance working range of 32-300 ohms which would be fine for the 650's, but I don't know if the mW/ohm translates to the same range on the V2.
