The Lab Gruppen IPX 1200 is a 1,200 W two-channel Class-D power amplifier with onboard DSP, delivering 2 × 600 W into 4 Ω from a single rack space. A 40-band parametric EQ engine, high- and low-pass filters, delay and the software-controlled Speaker Protect Limiter handle loudspeaker processing without an external controller, configured from the front panel or over the network via IPX Controller with amplifier auto-discovery. AES3 and analogue inputs with redundant failover suit touring rigs, portable corporate AV and installed systems alike.
