The new STI series integrated amplifiers offer unbelievable value, and sonics that rival units costing many times more.
If you're looking for the best deal on an integrated amplifier which also provides the resolution and clarity as those costing many times over, look no further. An extremely wide sound stage and imaging that takes you to the music are just a few attributes of our latest creation. Many of the features derived from the STP preamp have given this unit an edge that many others are looking for.
It all starts with our proprietary fully balanced dual FET unity gain buffers on the front end to welcome incoming signals. Our true resistive-ladder volume control is fed from the FET input stage and offers exceptional tracking. Our line stage that couples the amplifier to the front-end offers a balanced output regardless of the selected input. This offers much better common-mode rejection, and a quieter background.
Some features the STI series have that others don't is the same HT bypass feature as the STP, and a loop through feature. Like the STP, you can connect a DC trigger cable to your Pre/Pro (and set-up the proper input in the setup menu) to automatically configure the unit for HT use. When an input is selected to be used as the HT input, the DC trigger can be activated by your Pre/Pro to “power up” the unit, and automatically set the volume to unity gain. This allows for all volume controls to be made through the surround processor. When the processor is shut down, so is the STI and connected gear through the DC trigger output. When 2ch listening is desired, then manual operation can be executed from the front of the unit, or through the remote.
With a set of balanced inputs, 4 sets of unbalanced inputs and a set of unbalanced outputs, connection possibilities are vast. Absolute phase and balance control are easily selected through the supplied remote for those out of phase recordings, and room adjustments to be made on the fly.
User interface is made easy with the VFD display and optical rotary encoder. Allowing input naming and HT Bypass input selection, the setup menu is easily accessed for customization. Several display dimming steps including “off” are available through the remote for stealth operation. Powering up the unit can be done several ways, by pushing in on the volume knob (power button), by pressing power on the remote, or by the remote DC trigger input when HT Bypass is selected in the setup menu.
