MSB Preamp Inputs?

Good morning MSB people,

As I sit here enjoying my new Reference DAC upgrade from the Premier, I find myself wondering what others are using the Preamps XLR inputs for?

Can you please share how (if at all) you use these connections?

Thank you!

Mike

Hi Mike,

I have the Cascade, but same XLR preamp inputs.

My phono preamp goes into one. My AVP (Trinnov) goes into the other. The L and R speakers are shared between my vinyl system (which is 100% analog all the way) and my surround system, and, of course, my streaming system,.

The XLR inputs, at least on the Cascade are dead quiet and do nothing (which is a good thing) but adjust the level with the passive resistor matrix in the Cascade.

So… could these inputs be used as a L/R home theater passthrough from my HT preamp? Ive always thought that MSB preamps are not to be used as a HT passthrough to the front L/R speakers.

Thanks

For sure on Cascade you can use an XLR input as passthough.

Just go into config and disable the volume control for the XLR input from your AVP. That way your surround system can control the volume level. (Notice the level is “–”, which means passthrough). You will have to adjust the L and R levels on your AVP to match the rest of the speakers in your surround system, but the is standard operating procedure for configuring an AVP.

I have been using 2-channel at home, but am considering making an effort to add a center channel and some satellites. What is your system set up with @Dan ? How far did you go and what would you recommend for the most effective setup. I don’t really have any interest in 13+ channels, really just considering a 5.0 or 5.1 setup.

I have been using this since I acquired my Ref DAC. it’s easy, simply connect the pre-out of your L+R from the AV receiver to your XLR input (my AV receiver Denon X-4800 doesn’t have XLR so I have RCA to XLR adapter on the DAC side) and set the Analog input on the DAC setting to “bypass”.

After that go to AVR setting and set the L+R to “pre-out” and you’re good to go!
Remaining channels: center / satellite / subwoofers are connected directly to AVR.

Hi Mike,

I have two XLR analog input modules in my Reference DAC. They are fed from separate Jeff Rowland Cadence phono preamps (one for stereo MC cartridge and the other for mono MC cartridge). The two Cadence phono preamps share a single BPS (battery power supply).

Okay, so I have the L/R XLRs out from my AV Processor (preamp) connected to the Analog inputs, but as long as I have other items connected (and on) to the DAC, it will not toggle over to the analog inputs when a signal is sent from the preamp. I have the input setting set to Smart in the DAC and the analog setting is in bypass mode.

I believe that this is because digital sources take priority over analog sources in the automatic input switching hierarchy.

Digital takes priority because there is no circuitry to detect active analog sources in our DACs. So all digital sources must be off, or use manual switching, or use a controller with RS232 to command the DAC to switch inputs.
