Title: question about HT-input
Post by: Ingber on July 17, 2025, 07:02:44 AM

Hi,

I was considering to build the Bottlehead Moreplay pre-amplifier. I currently own a Musical Fidelity M6i integrated solid state amplifier. It has a Home Theater RCA input (HT-input) that allows to "bypass the volume control". Am I correct to assume that I can connect the output of a pre-amplifier to this HT-input, thus using the M6i as my power amp?

Best regards,

Ingber

From the M6i manual:

To use the AUX/HT input as a HT input, move the AUX/HT switch to the HT position. This input is now
unaffected by the volume control, allowing volume control on an external Home Theatre processor to be used
directly. Connect Home theatre or other source outputs to the AUX input RCA sockets (see page 7). Select
AUX input by pressing the AUX button so AUX LED is lit.
IMPORTANT: Take great care when using the input in HT mode. Ensure that the volume control is turned right
down on the HT processor when first setting up. The HT mode is designed for sources which require their own
volume control to be used. Connecting sources in HT mode with no volume control could result in damage to
hearing and/or speakers due to uncontrolled loud sounds.


I did also double check the input impedance, and it's adequately high so this should work fine.
