Zero noise RCA/PHONO/AUX selector
The TC-7230 noise free audio selector is a high precision passive
two way switch utilizing RCA connectors especially suited for low
noise applications.
Most other switches are really designed for high level or 'AUX'
level, so they can introduce hum and other noise when used with
extremely low level signals.
The TC-7230 is suitable for use with turntables as well as audio
amplifiers for two way switching due to its independent Left and
Right channel isolation.
The TC-7230 is also bi-directional. So it can instead be used to connect the output of one audio device to the inputs of two amplifiers, or share two pre-amps with two power amps.
Many applications are possible, especially when you need a noise free selector.
The TC-7230 is fitted with two earthing terminals for the ground wire from turntables if used to switch turntables.
