Design Features
There are many reasons why the STI-v2 series integrated amplifiers are better than the competition. To start with, the
volume control in the STI-v2 is a true-resistive ladder type that offers truer linearity and superior 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-v2 integrated amplifiers. In the setup menu, you can select the loop
feature to insert a digital crossover or similar devices into the audio path. When the loop feature is activated, Input 5
becomes loop in, and the AUX out becomes loop out.
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 managed via the included full-function remote.
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. Powering up the STI-v2 can be done by pushing in on the volume knob, by
pressing power on the remote, and by the remote DC trigger in when HT Bypass is selecting in the setup menu.
When an input is selected to be used as the HT input, the DC trigger can be activated by a surround processor 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-v2. When 2-ch listening is desired,
then manual operation can be executed from the front of the unit, or through the remote.
Front Panel Operation
The front of the STI-v2 offers several features, power on/off, input selection, volume control, muting, setup routine,
and display for user feedback. For phase, balance, and dim control, the remote must be used. To enter the setup
mode, input up and down must be pressed simultaneously with pushing in the volume knob. Once in the setup
menu, input up/down is used to scroll through the settings, mute is used to select the setting for adjustment, and the
volume knob is used to adjust the setting. For input naming, the volume control is used to select the character and
the mute button to move to the next character position for adjustment. Once all settings are made (they are
automatically saved once changed), the setup menu can be closed by pressing and holding the power button
(volume knob) at any time.
