Let the SA3 be your hub for hi-fi. Featuring five Line-in connections, plug-and-play a wide range of audio sources including CD players, cassettes, network streamers and more. A dedicated phono (MM) input is also included, rounding the total up to six and providing a platform for retro turntable enthusiasts. A convenient subwoofer output lets you open the bass range of your speaker system and expand to a 2.1 home audio setup.
Express yourself. The IOTAVX SA3 is capable of producing confident vocals and an open soundstage. Hear instruments in more realistic detail. This amplifier can provide a continuous 50W two-channel power output at 8Ω load and up to 100W for hungrier 4Ω speaker systems. Thanks to the subwoofer output, your audio will sound full and responsive, qualities necessary for high fidelity audio.
As well as two-channel drive, the SA3 has also been provisioned with a Mono mode switch, making bi-amping a more accessible option for the curious and practiced alike. Working especially well with power amplifiers such as the IOTA VX PA3, split the output load and dedicate up to 180W (4Ω bridged) to speaker systems not usually compatible with amplifiers of this size. 12v triggers are also available for synchronised control.
Along with six analogue connections, the IOTA VX SA3 hosts both optical and coaxial inputs, letting you connect digital audio sources as well as providing you with an easy upgrade for television speakers and smaller screens, outputting a 2.1 audio experience.
Every ear is unique. That’s why having advanced audio level adjustment is critical for a modern home system. As well as volume adjustment from the front panel, treble and bass levels can also be set using the remote control. Tune music to your taste.
The SA3 has been packed with their intuitive Bluetooth adaptor, attachable via the extension port on the rear of the amplifier. This establishes a quick, wireless and distance streaming input for music via phones, computers and other compatible devices.
Please Note: It is important that the Amplifier Mode switch on the rear of the unit is set to Mono when bridging with external amplifiers. When set to Mono mode, the IOTAVX SA3 will deliver right channel audio.
The KEF Q350 speakers are equipped with a 165mm Uni-Q driver that puts you at the centre of the action. The 25mm vented aluminium tweeter gives the audio a boost and delivers high frequencies that elevate your entertainment. The aluminium cone is home to Z-Flex technology, allowing for reduced distortion. With the addition of a waveguide, the KEF Q350 speaker creates a wide-reaching sound that you'll love listening to.
The KEF Q350 bookshelf speakers offer great sounds that are enhanced by the magnetic grilles, these grilles will also provide visually pleasing aesthetics. The solid speaker cabinet can be easily placed on KEF stands that will fit safely next to your TV or HiFi setup.
Computational fluid dynamics(CFD)port design, positioned at the back of the unit, provides a stunning bass performance that keeps you engrossed in the sound. The KEF Q350 speakers also offer a 63Hz-28kHz frequency response, 87dB sensitivity, and 8 ohms nominal impedance to create audio that you will not want to turn off.
