Yes but with some caveats. Most modern amplifiers don’t have pre-out/amp-in sockets any more. If yours does, you can connect the SHD between the pre-outs and amp-ins. A more typical situation is to connect all sources directly to the SHD and the SHD output to one of the amplifier inputs. Set the gain on the amplifier so that -10 dB on the SHD corresponds to the loudest that you will play music.
