LM3875 Chip Amp Buffer NIGCB

[LucasAdamson]

I am building my chip amp up into an integrated amp, by using the B1 buffer board and an as yet undecided RIAA phono stage (when they arrive).

My question is this:

How do I get more inputs into the B1 buffer? It comes with two, but after DAC and phono, I'd like another for tuner, and preferably another for AUX use. Ideally the DAC and phono and AUX would be line level inputs, but shouldn't the tuner input be lower than line level volts, or are most tuners outputting line level these days?

Many thanks
Lucas

Find a rotary double switch with enough positions to suit your input needs.

Ah, I guess it really is that simple...so why are there two separate inputs on the B1 board?

If you refer to this:

then it's probably because Mr Pass didn't need more inputs.
