Many have asked us for a remote control for our Django TVC passive preamp. It’s great to adjust the volume from the sofa.
A few years ago we made a remote-controlled step motor for our 23-steps Seiden switch, it worked initially, but there were two major problems. Firstly, the switch stopped at the wrong position at times. Secondly, the step motor was quite noisy. Now our new relay-based remote control overcomes these two problems – and it’s reliable, durable and quiet.
How does it work? When an electric current passes through the coil inside the delay, a switch opens or closes the connection. It’s a mechanical switch like the Seiden switch. Audio signal only passes from one pin of the relay to the other pin. By using high quality audio grade relay, the signal path remains clean.
How much will it cost?
It costs more than other relay-resistors volume control because it uses a lot more delays. Below is my estimation:
Volume control, display, and remote control : about $219
Volume control, display, remote control and channel control : about $289
Remote control : 2 buttons for volume control and 2 buttons for channel control
Front panel control : Press the knob to change channel or turn the knob to adjust volume.
Drill one 15mm hole for a number display and one 5mm hole for IR receiver (optional: one 8mm hole for switch shaft for manual selection)
The first prototype will be done in early December, 2014.
