Samson Technologies Qh4 4-Channel Studio Over Ear Wired Headphones Amplifier, Black

For studio use, if you have a group left n right output in your mixer, you probably need this one... professionally built-in amps, super smooth audio transitions while operating volume knobs, added features with a mute button n master volume knobs..makes it easier to use.

Good quality, good control,

Good quality,nice sound same as source sound.

This product has a problem on the output pre amp

Bags of power. Very clean. The individual amp for each headset is a good feature. If someone plugs in a headset of different impedance, it doesn't effect the whole output level. Used for recording overdubs in my studio. Everyone brings their own cans.

Estuvo un poquito más caro de lo que me imaginaba, pero es muy bueno. Se conectan 4 personas y cada quien controla su propio volumen.

Amplificatore dal rapporto qualità prezzo stellare come con altri prodotti dello stesso marchio. Pilota cuffie difficili come AKG, Beyer e altre con un sound neutro e privo di colorazioni e quindi senza alterarne le caratteristiche, ma restituendo un equilibrio degno di nota con buona dinamica e risoluzione con un prodotto che ha un costo irrisorio ma una qualità che va oltre e di molto il suo prezzo. Consigliato e super consigliato Samson - QH4 in studio e anche per un ascolto hifi neutro e privo di enfasi con la possibilità di gestire diverse cuffie in contemporanea. Grande prodotto a dispetto del prezzo . Tenere il volume generale a ore 12 e regolare ogni cuffia col proprio gain. Five star .

Very useful headphone splitter for studio. Especially as you can have up to four headphones with separate volume controls! Great for ensembles and backing vocalists. N.B. When powering on, it can make weird clicks, static & distortion while it ‘warms up’.

Honestly this splitter is fantastic as far as I can tell. It's much higher quality than the horrendous HA400 / Behringer rebranded multi-out splitter amps (I own one of those). The HA400s are so terrible that, if you can't hear what they're doing to the audio quality, you shouldn't worry about any audio hardware you buy, because that's about as objectively bad as it gets.This splitter has no signal degradation that I can detect. I use it to compare multiple cans at the same time. The individual volume knobs + master is great to let you make each compared headphone have the same volume, and then change the master volume at the same time. There DOES appear to be a difference between the master all the way up and individual low, vs vice versa of individual high and master low, but only at very high volumes. The unit definitely does produce noise, but again only at deafening volumes. I can't hear any added noise to the signal at loud but bearable listening levels.I regularly plug all of my headphones into this, independent of the sound source. It's convenient to always have the same sized jack going to the audio source (this supports aux in and 1/4 trs which is great), and then to plug in whatever headphone cable size I want with adapters to the QH4.I don't think this unit contains $70 worth of hardware, but it's sturdy, and has held up for a while now (at least a year?) with no damage or signal degradation despite a few times i've dropped it. The knobs all feel great to turn, the base has good friction against my desk, and audio clicks and pops are minimal turning it on/off. Again I don't think there's $70 worth of physical material in here at all, but I also don't regret paying $70 for it after using it extensively.
