Design features There are many reasons why the STI series integrated amplifiers are better than the competition. To start with, the volume control in the STI is a true-resistive ladder type that offers truer linearity, and supreme sonic quality. The line-stage within the integrated doubles as an unbalanced to balanced converter which provides a balanced signal from unbalanced inputs. A loop in/out feature is also on hand with the STI integrated amplifiers.
3. 4. 5. 6. Release all the buttons when the set-up screen shows up on the display. Use the input up and down buttons to navigate the menu function. Use the mute button to select and enter the menu function. Use the volume knob to change the setting with-in the menu function. (You can press the input buttons to save the settings and move to another function) 7. Once all settings have been made, press the power button again (knob) to set and store you selections.
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.
4. If you can hear the amplifier turn on and off, but there still isn’t any sound, make sure you are getting a signal to it. 5. Verify that the input selector is selecting the proper input for what you have connected. 6. If the input is in the proper position and still no sound, then try replacing the interconnects to verify the connection between the amplifier and source. 7. Verifiy that the interconnects are conducting by replacing them on a different set from a connection that you know works. 8.
