Introduction Congratulations on your purchase of the World acclaimed “Sterling” triode amplifier from Audion. Your Audion Amplifier is the result of nearly 20 years exhaustive research and development culminating in our current world class product. The chassis is made of anodised aluminium designed to minimise magnetic interference and reduce internal noise to an absolute minimum. All our amplifiers are hand built using only the finest components available.
Getting Started Upon opening your box you will find: 1. 2. 3. 4. 5. Audion Amplifier Audion Power cord This User Manual Product Registration and Warranty form Valves/tubes Please keep all packaging and store in a dry and safe place. Carefully remove the Audion Amplifier from its packaging and store both the box and the foam in a safe place, should, in the unlikely event that you ever need to return your Audion to us for maintenance, upgrading or servicing.
Valves/Tubes You will now need to place the valves/tubes into your Audion. The Sterling Mark 1 and 2 use a E88CC or 6922 in the left hand side front and a 5687 on the right hand side front.
Please Note Inserting the valve/tubes the wrong way around will at the very least damage the valve base pins and may result in a loose valve causing crackling. WARNING – Do not attempt to remove or replace valves/tubes whilst your Audion is in operation, as by so doing you could destroy the amplifiers circuitry – risk electrical shock to yourself and invalidate your Audion’s warranty.

outputs marked 2 x black & 2 x red. These are designed for “Biamping”. The ground lift switch is used to effectively reduce a ground feedback loop and hence noise from some installations. Finally connect the power cord to a mains electricity supply. Before proceeding – Are all the connections fitted correctly and securely tightened? Finally Check again – make sure everything is correct. Using your Audion Congratulations you are now ready to switch your Audion on.
The remote model has three buttons – Up, Down and Record. The up and down buttons change inputs from 1 to 5 and the Record button allows recording via RCA pair No. 6. In general use your Audion should give many years of trouble free use. The anodised aluminium chassis should be wiped regularly with a clean lint free cloth to remove dust. Under no circumstances should solvent or solvent based products be used on or near your Audion.
