Four-channel headphone distribution

The ELZONYX HA400 splits one stereo source into four independent headphone feeds, each with its own volume knob. It suits studio monitoring, band rehearsals, podcast recording and any situation where several listeners need the same mix at personal levels.

Low-noise JRC4580 amplifier chip

A single JRC4580 op-amp drives all four outputs, keeping the signal clean and adding gain without audible hiss. The bundled 12 V power adapter powers the circuit so no batteries or USB supply are required for operation.

Compact metal chassis with 1/4" TRS connectors

The aluminium enclosure measures 90 × 55 × 40 mm and weighs 0.29 kg, so it fits on a desk or pedalboard without crowding other gear. Quarter-inch TRS jacks on the front panel accept standard studio headphones and patch cables for quick setup.

Questions about this item

Will the JRC4580 op-amp chip need replacing over time?

The JRC4580 operational amplifier is a solid-state component soldered to the board and is not designed to be user-replaceable; it has no moving parts and typically lasts the life of the unit.

What limits performance first during a long recording session?

The 12 V power adapter and the amplifier's thermal design set the continuous-output ceiling; the metal chassis helps dissipate heat, but sustained high-volume use on all four channels will reach that limit before the op-amp does.

How much noise or heat does the HA400 produce when running all day?

The low-noise JRC4580 chip keeps the noise floor very low, and the compact metal enclosure (90 × 55 × 40 mm) acts as a passive heatsink, so the unit runs silently and stays only slightly warm during extended operation.
