These headphone amps are louder than you're ever likely to need for session and stage use, so be careful with that level control! Headphone Impedance Working Range : 32Ω - 600Ω

The HP4 from PreSonus answers the need for a headphone distribution amplifier with professional specifications in a small package at an affordable price. The HP4 features four discrete headphone outputs on the front panel each with its own volume potentiometer and 150mW of amplification per channel. The HP4 also features adjustment over control

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.

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

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.

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.
