Power adapter for On-Stage HA4000

This AC adapter delivers DC power to the On-Stage HA4000 4-channel pro headphone amplifier. It replaces a lost or damaged original supply and is built as a non-OEM unit with CE, FCC and RoHS certification. The barrel-tip connector must match the amplifier's input before use.

Worldwide input range

The adapter accepts AC 100 to 240 V at 50 to 60 Hz, so it works on mains supplies worldwide without a separate voltage selector. It provides the headroom the HA4000 needs for four headphone channels. No output voltage or current values are supplied, so exact power limits cannot be stated.

Barrel-tip connector constraint

The barrel-tip size is the critical compatibility check; if the tip does not fit the HA4000 the adapter will not work. The unit includes over-voltage and over-heat protection for safe operation. Long-term use calls for adequate ventilation and a dry environment.
