Full Description
IOTA VX PA3 Stereo Power Amplifier
Class AB Amplifier
The IOTA VX PA3 Stereo Power Amplifier houses a toroidal transformer which produces a colossal amount of power that is sure to boost the power level of any input signal. The Class AB amplification design combines awesome sound fidelity with high efficiency to get you engrossed in an audio utopia. The PA3 can generate 100W of power per channel at 4 ohms in stereo mode to create a robust sound. If you need more power, no problem, the IOTA VX PA3 can be used in mono mode and transmit 180W through one channel.
Connectivity
With multiple RCA inputs, the IOTA VX PA3 amplifier can connect to virtually any AV component so you can enhance the sound of your entertainment. The preamp outputs mean the high-quality signals can be transferred to a separate amplifier to further augment the sound. You can also use the PA3 to switch external devices on/off by using the trigger and dimmer inputs/outputs.
Great Design
The slim, compact design means you can place the IOTA VX PA3 Stereo Power Amplifier within most HiFi cabinets. The PA3 is also tailor-made to be placed below the IOTA VX SA3 stereo amplifier so you control your audio from one place. The standby indicator light will also notify you whenever the PA3 is switched on/off.
Key Features
- Class AB amplification technology – higher efficiency than Class A and lower distortion than Class B
- High-quality steel manufacturing
- Use just as a pre-amplifier – using the PRE-OUT jacks, you can output the signal at the amp-in level
- Amplifier mode – switch between stereo and mono (bridged) modes
- Trigger in/ out – link your Hi-Fi system together
- Dimmer link in/ out – link the brightness of connected Hi-Fi components
IOTA VX NP3 Network Streaming & CD Pre-Amplifier
Connect Your Way
The NP3 runs the full gamut of connectivity choices. With this accessible pre-amplifier, you’re sure to find an input for your music. Including not one, but two USB-A inputs (front and back), connect external pen drives or hard drives for quick and easy MP3 playback. A USB-B input is also available for PC files, with up to 24 bit / 192 kHz resolution. As well as USB, the NP3 is ready to connect via digital optical and coaxial inputs and outputs, so you can synergise with your home audio system in more ways than one.
Streaming the Hits
One of the main draws of the NP3 is its high-quality streaming capabilities. If you’re not tapping into your CD collection, why not tune into an enormous catalogue of radio channels? Including FM, DAB+ and internet radio, you’ll never be short of things to listen to. Connecting via WiFi or ethernet also gives you access to network streaming, letting you listen to instant music services such as Tidal, Deezer and Spotify. Thanks to DLNA and UPnP, a LAN connection is all you need to play music stored on local servers.
Total Control
The IOTA VX NP3 has the means of being more than just another component in your audio system. Controllable either by the ergonomic front-panel dial or via the handy remote control, volume adjustment is completely in your hands. Whether as an audio source or as a full pre-amplifier for other equipment in your home audio chain, connecting to a stereo power amplifier is all you need to listen to your favourite music. The remote also lets you read track information, dim the display and select your source.
CD Player
A letterbox-style, mechanised CD slot is situated at the centre of the IOTA VX NP3’s front panel, ready to take on your collection. So whether that’s below 10 or over 100 discs, make this pre-amplifier a home for your music. CD WAV files and MP3 are fully supported, widening the scope of just what you can play here.
Build Quality
IOTA Enterprises have engineered the NP3 for strength. They know that people rely on music daily and want you to be able to listen for a long time to come. That’s why they have used a heavy steel casing to increase durability, as well as promote coherence and minimal resonance with high-quality circuitry and components.
Bluetooth Adaptor
As the final piece of the puzzle, the IOTA VX NP3 can be fitted with the IOTA Bluetooth Adapter (sold separately). This extension piece equips the pre-amplifier with a streamlined wireless connection to your smart devices. You can use this to mirror audio from your tablet, smartphone or compatible portable music device.
