It provides the complete and versatile control of audio signals without the introduction of audible distortion or colouration. Quality design and special features make it an extraordinary value: dual turnover tone controls permit more precise tone adjustment. Three phono inputs include one with a built-in preamp for moving coil cartridge. Selectable cartridge capacitance provides flattest frequency response for your cartridge. Phono overload indicator assures correct sensitivity. Magnetic phono preamp is designed for lowest noise with cartridge connected (rather than preamp shorted) for super-quiet performance under real working conditions. Dual turnover filters permit more subtle filtering. Built-in infra-sonic filter reduces rumble and low-frequency noise from your records. Versatile record mode lets you record from deck 1 to deck 2 or vice-versa while listening to source or tape. Independent loudness control is based on new, more accurate data.

The AP-1800 switches up to 1500 watts (maximum) of power.
