romnation Posted October 20, 2019 Share Posted October 20, 2019 I realize how dangerous this could be if something else were to generate a sound at the full volume of the output, but would this work theoretically without damaging the speakers? Running straight from a DAC without volume control (such as Bryston BDA-3) straight into an amp only amp with only high level inputs. If I use only the volume control in say foobar2000, would this be possible? Link to comment
mansr Posted October 20, 2019 Share Posted October 20, 2019 Sure, that'll work. Just be careful not to accidentally play something very loud. tmtomh 1 Link to comment
mitchco Posted October 20, 2019 Share Posted October 20, 2019 Agree with mansr. I have been doing it for years into a 3 way active system with no loud mishaps. In my case I use JRiver's internal volume control which also has volume protection. Not sure if foobar2000 has that or if it even really matters. As mansr noted, just need to be a bit careful is all. tmtomh 1 Accurate Sound Link to comment
Kal Rubinson Posted October 20, 2019 Share Posted October 20, 2019 I agree with mitchco and mansr. For added convenience, I use a DROK physical volume knob to control the internal volume control in JRiver. It might work with foobar: tmtomh 1 Kal Rubinson Senior Contributing Editor, Stereophile Link to comment
mitchco Posted October 20, 2019 Share Posted October 20, 2019 Wow, Kal, that's cool! How do you hook it up to JRiver's internal volume? Accurate Sound Link to comment

It was very complex. First, I had to plug the cable into the control box. Second, I was required to plug the other end of the cable into the first available USB port on my PC/Server. Finally, and at long last, it was necessary to turn the knob in order to adjust the volume. Also, it cost me almost $30, an outrageous price for even such an essential device. 😊 AnotherSpin, kumakuma, tmtomh and 1 other 1 1 2 Kal Rubinson Senior Contributing Editor, Stereophile Link to comment

It is said to be programmable but, so far, I have not figure out how. Out of the both, it works fine with JRiver (volume control and push on/off for mute) but not with Roon.

Sometimes when you use the midi the control the volume you can accidentally push them or the mouse can simply misbehave at times. I was using Mytek DAC and it is possible to trim the volume to prevent such accidents. Not sure if your DAC could do that. ST My Ambiophonics System with Virtual Concert Hall Ambience Link to comment
cjf Posted October 22, 2019 Share Posted October 22, 2019 As others, I do this also but in a somewhat Hybrid manor. I use ROON's DSP software VOL control in my setup. Even though my DAC does have a VOL knob (Benchmark DAC3) I choose to keep its -10db VOL PAD in place and the VOL knob active instead of fully disabling it (which is an option). During normal listening sessions the DAC VOL knob is buried at Full Tilt and ROON's VOL control is handling the heavy lifting but before I get to that point I always turn on my system with the Benchmark VOL knob turned all the way down. I start my Playlist with physical knob all the way down and slowly roll it up to full blast. This is for pure paranoia purposes and not because of any event that caused unexpected full output from the software VOL control in ROON. But to the OP's point, I choose to keep an extra layer of protection in place to save me from my own stupidity, if nothing else. Also, with ROON, they have safety features available as well, which I also use. There is a Safe Limit and a Max limit setting. The Safe limit only allows the "Slider" for the VOL to go as far as you set it in the config. Any desired output beyond the "Safe Limit" requires additional presses of the "+" button for each increment up to the "Limit" you set. This prevents a fat finger action that would result in full output unexpectedly. I had my reservations of this approach for a long time too but at the end of the day its probably the best VOL control one can use and one that most likely eclipses even the best of PreAmps analog VOL controls. I saved 5 figures going this route over the PreAmp I was going to buy. My Audio System -Last Updated May 20 2021 Link to comment
