The IOTAVX SA3 was designed as a high-quality stereo amplifier. In addition to a variety of analogue inputs, the amplifier also has optical and coaxial digital inputs. Together with the optional Bluetooth adapter, which can be connected at the rear, the signals of these digital inputs are internally converted with an excellent Wolfson DAC. For our turntable friends, this is taken care of, the SA3 has an MM Phono stage (Input Capacity 220pF). The easy-to-read display on the front panel makes controlling the SA3 easy and convenient to use with the remote control. The lighting of the display as well as the LEDs on the front can be switched on and off completely. With powerful 100Watts per channel @ 4 ohms, power is always available to drive the speakers. If more power is required, the integrated amplifier can also be used in mono mode (bridged) and combined with another power amplifier (such as the IOTAVX PA3). In this case, the SA3 then provides 180W @ 4 ohms per channel. In addition to this sophisticated and high-quality pre-stage design, the amplifier section of the amplifier also impresses with its particularly efficient design. The Class AB amplifier technology achieves a high degree of efficiency and thanks to the special amplifier circuitry, offers minimal distortion and maximum precision to the sound. Music enjoyment at the highest level and with maximum dynamics is thus nothing in the way.


The SA3 integrated amplifier has tone control, which allows an optimal adaptation of the sound to your listening room and your taste. Both bass and treble can be boosted or stepped up by up to 10 dB in 1 dB increments. In addition, the balance between left and right speakers can be adjusted, also here in 10 steps to the left and 10 steps to the right.

IOTAVX Bluetooth connectivity 

In addition to digital and analogue connectivity, music can be streamed directly to the SA3 from a smartphone or other Bluetooth-enabled device using the optional Bluetooth receiver module. This module plugs into the extension port directly on the back of the SA3 and supports the latest Bluetooth AptX audio standard (CD quality).

Quality Promise

The IOTAVX SA3 not only sounds fantastic, but we also manufacture it with heavy steel housing and high-quality components. This ensures that you can enjoy your IOTAVX SA3 for a long time.
