The Input Selector is a relay-based input selector which supports the selection of one of six stereo inputs. It can be used as a passive preamp by adding a volume control, such as the Selector Switch & Volume Control. An active preamp, or a preamp with gain, can easily be implemented by adding the Universal Buffer. This will result in a preamp with six stereo inputs and both balanced and unbalanced outputs. Balanced inputs can be implemented with the Universal Buffer as well.

The control input to the Input Selector is compatible with 3.3 – 5.0 V CMOS and TTL logic levels. This makes the Input Selector easy to interface to the many popular micro controller circuits, such as the Arduino. 

The 45 × 112 mm gold-plated PCB is made in Canada. 

Technical Documentation

  • The features of the Input Selector are listed below.

    • Relay-based input selector with six stereo inputs.
    • High channel separation and excellent off attenuation. 
    • On-board 5 V regulator powers the relays.
    • Relay Saver technology reduces the power dissipated in the relay coils by 36 % once the relay has switched, thereby enhancing the reliability and longevity of the circuit. 
    • Gold plated relays, designed specifically for small-signal use.
    • Connection to volume control by 10-pin, gold-plated connector.
    • 3.3 – 5.0 V compatible logic control inputs with ESD protection for audio input selection.
    • Gold plated PCB. Made in Canada. The circuit module arrives fully assembled and ready to go.
