The QSC ISA300Ti is a two-channel installation power amplifier with a built-in output transformer, giving it fully isolated 25V, 70V, and 100V distributed-line outputs in addition to low-impedance operation. The integrated transformer (the "Ti" designation) makes it purpose-built for constant-voltage systems in large commercial spaces, paging and background-music installations, and venues with long loudspeaker runs. It delivers 185 watts per channel into 8 ohms, 280 watts into 4 ohms, or 300 watts per channel on the 70V/100V taps, and can be bridged to mono. Housed in a robust three-rack-space ISA Series chassis, it offers balanced inputs, detented level controls, and full protection.
