I should also told everyone that this is an integrated tube amp. There is a connection for CD, SACD, DVD, and tuner, all of which are controlled from one multi-position switch. There are also two pre-amp O/Ps, which are not dedicated to anything. I am using one of the pre-amp O/Ps to drive the sub. I'm feeding the positive wire into the Line In+ terminal, and the negative wire into the Line In- terminal.
The main speakers are connected to the amp speaker O/P. The sub low pass knob is set to 60 degrees, the phase to 0 degrees, and volume is at 12 o'clock.
The integrated amp is just a plain-Jane integrated amp, with no processing.
