Cinnamon Hill Art Rev 5 Headphone Mixer Amplifier Installation Instructions rev 1 Photo 1 The Cinnamon Hill Art Headphone Mixer Amplifier Rev 5 This is the latest version Rev 5 of the Cinnamon Hill Art Headphone Mixer Amplifier HMA When you plug in your headphones the organ speakers go silent This is called muting The Cinnamon Hill Art HMA has an internal MUTE function eliminating the external organ MUTE wiring This also means that the HMA is no longer restricted to the Allen Organ amplifiers containing a Mute function Any other brand can use the Headphone Mixer Amplifier as long as you can find the organ amplifier inputs and they are RCA plugs and jacks Drawing 2 on page 7 explains how the HMA is connected Installing the Cinnamon Hill Art Headphone Mixer Amplifier should not take more than one or two hours You will then be able to listen to your organ without disturbing others in the room The installation in this manual is on my Allen ADC 3100 two manual four channel organ There are no connections to the organ other than the audio outputs from the organ mixer and the audio inputs to the organ amplifier The HMA has no effect on the organ sound going to your speaker s other than muting The installation requires four main steps 1 Mounting of the headphone jack box 2 Mounting of the Headphone Mixer Amplifier circuit board and testing the Jack Box 3 Wiring the audio cables 4 Installing the power supply Step
