This lightweight, modified class H amplifier has been designed to the same high standards of reliability and sound quality that our customers have come to expect of all OHM products.

As with all TK Series amplifiers, the TK-45 will deliver their rated power over the entire audio bandwidth, and a resonant switchmode power supply with a large reservoir gives extremely high peak power without any “bass sag”.

Optical limiters keep mains input and output currents within a safe operating area at all times, whilst maintaining transparent sonic performance.

Power Reduction Circuitry (PRC) controls on the rear panel, linked to the limiter thresholds, allow each channel to be independently set so that different speakers can be safely connected to each channel.

Running cool in even the most difficult conditions,the TK-45 can deliver over 2500 W into 4 ohms with both channels driven, and an impressive 8400 W (4Ω) bridged with outstanding distortion and noise figures right up to maximum output.

The amplifier, of course, includes full DC, VHF, thermal and short circuit protection to ensure continuous trouble-free service.
