Quite a few people on various forums are concerned about the emulated out of our DSL20H and DSLCR amps. It seems that there is a set level for the emulated line out and headphones which can only be adjusted with either the guitar volume knob of gain channel knob. The channel volume does nothing to the line out/headphones only to the speaker output.
Is this normal behaviour? Where the gain knobs are the only controls on the amp that increases the loudness of headphone/line out.
There is an update for this, if your amplifier requires it please contact your nearest service center.
Thank you for your e-mail regarding your question, this is normal so you can adjust the level of the output compared to the level of the line out.
Of course the volume/presence/resonance will not work with the line out. Whoever is saying they "fixed" this is lying or confused.
The emulated out is after the preamp, while the volume/presence/resonance are power amp controls, so of course they don't work. If you're trying to use headphones, you should plug the emulated out into a mixer, headphone amp or audio interface, and use your volume controls there.
