This is an open box return due to the customer changing their mind on system specification. The packaging has been opened, but the amplifier is new, unused, and comes with a full UK warranty.

This compact, ultra-high power density DSP amplifier delivers four channels of 125 W or two channels of 250 W. All from a convenient 1U half-size design.

The IA125-4 is a deceptively powerful amplifier that packs ultra-high-density amplification into its compact 1U half-rack form. It delivers 4-channels of 125 W or 2-channels of 250 W.
