NEVER connect either output to a ground point! Doing so may cause damage to your amplifier and/or
connected gear.
The binding posts that you will find on the STI series are made of nothing but the best. Each binding post
is made of highly ductile “OFC” copper alloy. Both clamping nuts are built out of one piece, and offers excellent
grip. All metallic surfaces offer a 24-carat gold-plating, and are non magnetic surfaces. The binding post will
accept 4mm banana plugs, spades of 6 and 8mm, and crimped cable ends up to 10 AWG. The easiest
connection is made with banana plugs, but be sure that you use the highest quality that you can find. Make sure
that the banana plugs fit snugly into the terminals. Some inexpensive banana plugs can cause a highly resistive
connection which can result in a noticeably higher distortion output to the connected speakers.
The RCA (unbalanced) jack is made with high quality gold plated copper, and should be properly
connected with interconnects of the same value. The Neutrik XLR (balanced) connectors are the finest balanced
connector on the market, and are the best possible option for connecting your amplifier to your sources.
Using the new W4S power and interconnect cables would be a great way to ensure your system is closer to
what we call “our reference”. We are now offering superior cables at an affordable rate that anyone can afford.

Your new STI series amplifier will deliver outstanding performance right out of the box. However, you
should plan on improvements as it reaches its normal operating temperature and once all of the components have
a chance to “settle in”. Our experience has shown that the amplifier has reached its’ potential after the initial 300
hours. You will find that the initial 100hours, the amplifier will start to shed the initial “brightness” and somewhat
harsh transitions. During the second 100 hours, the amplifier will start to become more fluid, and smoother
overall. The remaining 100 hours is where the lesser of the change happens, and you might still notice
improvements over time.
After the initial break in period, your amplifier will be ready to perform within minutes of powering it on.

No sound?
If you have your input source and speakers connected, and you can’t get music to play, check the following:
1. Verify that the power cord is plugged in and that the outlet is powered up.
2. Check the front panel and make sure that the blue light is on.
3. If the front panel is blue and there still isn’t any sound, put your ear next to the tweeter of your speaker
and have someone turn your amplifier off then on again at the rear switch. You should barely hear a
click when the amplifier is turned on and off
