{"product_id":"alctron-ha-408-440572","title":"HA 408","description":"\u003ch3\u003eShared monitoring for the studio, podcasting and rehearsals\u003c\/h3\u003e\u003cp\u003eLetting several people hear the same source should not complicate a session. The \u003cstrong\u003eAlctron HA 408\u003c\/strong\u003e centralizes signal distribution to multiple headphones while retaining separate level control for each of its four channels. It therefore meets the needs of small working groups who want to listen together without relying on a single headphone output.\u003c\/p\u003e\u003cp\u003eIn the studio, this stereo headphone amplifier allows several musicians to monitor the same audio program. In podcasting, it makes shared monitoring easier for guests. It also fits naturally into singing lessons, for monitoring an accompaniment or analyzing a take together, as well as rehearsals when headphone monitoring is preferable to playback through speakers.\u003c\/p\u003e\u003cp\u003eIts capacity reaches \u003cstrong\u003e8 headphones across 4 channels\u003c\/strong\u003e. Volume controls are therefore independent per channel, rather than per headphone when two headphones share the same channel. This distinction allows connections to be organized according to the participants' monitoring preferences.\u003c\/p\u003e\u003ch3\u003eVersatile connections to simplify your setup\u003c\/h3\u003e\u003ch4\u003eThree inputs combined automatically\u003c\/h4\u003e\u003cp\u003eThe HA 408 features inputs in 3.5 mm jack, 6.35 mm jack and RCA formats. This variety makes it easy to integrate with audio equipment using different connectors. You can therefore choose the connection suited to your source without building your entire setup around a single format.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003ethree inputs are mixed automatically\u003c\/strong\u003e: connected signals can be combined for monitoring without adding a dedicated mixer for this task. This operation is particularly useful when several elements need to be heard together. To adjust their relative balance, plan to adjust the levels on the source devices using the controls available on them.\u003c\/p\u003e\u003ch4\u003eFour controls to adapt the monitoring level\u003c\/h4\u003e\u003cp\u003eEach channel has its own volume control. A participant can therefore request more level on their channel without imposing this change on the others. This is a practical advantage during group sessions, where the headphones used and monitoring preferences may not be identical.\u003c\/p\u003e\u003cp\u003eThe outputs are provided in 3.5 mm jack and 6.35 mm jack formats. The HA 408 supports headphones with an impedance ranging from \u003cstrong\u003e16 to 250 ohms\u003c\/strong\u003e, a range that allows it to be used with various models. Checking your headphones' impedance remains useful before preparing your setup.\u003c\/p\u003e\u003ch4\u003eA compact format to keep your workspace clear\u003c\/h4\u003e\u003cp\u003eWith dimensions of 140 x 98 x 31 mm and a net weight of 408 g, the HA 408 takes up little space next to an audio interface or recording station. Its metal enclosure complements a design focused on one specific function: distributing stereo monitoring to multiple users.\u003c\/p\u003e\u003cp\u003eIts rated power reaches 290 mW per channel at 100 ohms, with a maximum gain of 22 dB per channel. The signal-to-noise ratio of over 98 dB completes these specifications. Together, these features provide a dedicated solution for \u003cstrong\u003emultichannel headphone distribution\u003c\/strong\u003e, without multiplying the number of devices required for a single session.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
