Product Research

Features

Overview: The Rolls SS412 passive source selector lets you run up to 4 consumer-level audio playback devices, using RCA outputs, to a receiver or amplifier with one set of RCA inputs. The SS412 is completely passive and does not require any power for operation. This means the source selector imparts no noise or distortion into the signal path. The front panel includes a convenient 3.5mm audio input for easily plugging in a smartphone or tablet without having to access the rear panel.

Rear Panel:

  • Inputs: Includes 4 pairs of RCA inputs for consumer-level audio playback devices (-10dB).
  • Outputs: Includes 1 pair of RCA outputs for running to a receiver or amplifier.

Front Panel:

  • Input Selector: A 4-way rotary dial lets you select an input source.
  • Level: Adjusts the output volume of the selected source. (Range: 0-10).
    • Note: The Level control works as an attenuator, since the source selector is passive.
  • 3.5mm Input (Input 4): This jack lets you easily connect a portable audio playback device, smartphone, or tablet to the front panel. This input runs in parallel with Input 4 and is selected as such.

Q
I want to hook you a 8 track player that has a recording feature- I don't think this will work?- advise please?

The Rolls SS412 4-channel source selector is used to connect up to 4 RCA line level audio source units to a single RCA input connection with input selection knob and separate volume for your stereo gear, Vaughan. For most 8-track players with a recording feature you'll need an analog RCA recording output on your receiver or preamp, and an RCA input available for playback features from the 8-tracks. If you need any help deciding the right parts for your specific goals, just give us a call!

Q
I have one vintage Marantz Equalizer I would like to share with two separate receivers (a Marantz 2285 and a Marantz 1300dc integrated amp) both running different equipment. Would the SS412 be able to select (back and forth) the equalizer for both these separate units?

Greetings Bill. Thank you for your question. The Rolls SS412 has 4 stereo inputs, and just the one output. You need something that has the one input and two outputs. You could accomplish this using two RCA Y splitters. https://www.crutchfield.com/p_703M22F/AudioQuest-FLX-X-RCA-Y-Adapter.html
