Better ADC for Line Input It uses TI Burr-Brown Audio PCM1861 ADC, achieving up to 192kHz/32-bit digital output, 110 dB SNR. Thus, it provides high-fidelity analog to digital conversion for input from a record player, MP3 player, or TV. Ultra-low Noise Clock, Power, and Circuit Design It uses an ultra-low noise clock, power supply, and careful PCB layout to achieve less than –110dB THD+N performance for analog audio output. AKM DAC and TI OP AMP for Better Line-Out Audio Quality It features a new generation AKM 4493SEQ premium DAC that is able to achieve a leading level of low distortion and wide dynamic range thanks to AKM’s Velvet Sound Technology. It supports up to 768 kHz PCM, ideal for the latest high-resolution audio source. Achieve 120 dB (A-wt) SNR, THD+N of 0.00032% (-110 dB) from 44.1k to 192k.

Simple system Direct to your AMP or powered speaker without external DAC. Audio quality is comparable with WiiM Pro connected to the external DAC.(up to £300 price). Compatibility Resolve compatibility issues with some (low-end) DACs that don’t handle the clock, variable sample rate/bit depth properly, or don’t support up to 24-bit/192kHz digital input. Better audio quality for analog input The better audio quality for analog input sources Cost Effective Save the external DAC and cable costs. The WiiM Pro Plus was a significant upgrade in terms of audio quality for analog audio input and output, total system cost, and system setup. These enhancements aimed to provide users with a more powerful, high-fidelity, and hassle-free music streaming experience compared to the previous model, the WiiM Pro.

The first thing you need to decide is how big you want the screen to be? Depending on how much space you have typical sizes are between 96 – 120 inches (measured diagonally). Domestic TV screens may be getting bigger all the time but once you go above 90" TVs they become more expensive and harder to hide. It’s tempting to go large, but its important to see the bottom edge of the screen from every seating position. Don't forget that if its too large you'll have to move your eyes to see the whole of the screen creating a feeling much like sitting in the first row of seats in a cinema, and potentially motion sickness! Choosing the right-sized screen It’s important to make sure your projector will fill the screen from its intended position. You can use the unit’s throw ratio information to discern this. Divide the distance between the projector and screen by the throw ratio and you’ll get the image width. It’s important to note that it’s image width not the diagonal. Image width x Throw ratio = Distance from screen If you have a screen that is 2.6m wide and a projector with a throw ratio of 1.3 you'll need to put the projector 3.38m away from the screen. As well as the size of screen, consider the type. Do you want a fixed model that sits on your wall or a roll-up option that can be hidden away after use? The answer depends on whether the room is a multi-use space. If so, hiding the screen away makes a lot of sense. In a dedicated home cinema room the fixed option is the way to go, because the screen is always ready for viewing and adequately tensioned to ensure a smooth, flat surface for the projector’s image. It also doesn’t need power to operate any motors. While the fashion with TVs dictates that a minimal border is ideal, we advise against carrying that through to projector screens. It’s best to get a fixed screen with a relatively wide frame. The frame should be covered with black light absorbing material, so that any part of the projector image that falls on it isn’t reflected. This means that millimetre perfect alignment of the projector’s image isn’t required and also that your picture is perfectly framed, helping it standout.

Building a home cinema involves several carefully considered steps to create an immersive and comfortable viewing experience. Here’s an overview: 1. Planning and Design a. Room Selection: Choose a room that can be dedicated to the home cinema. Basements are popular choices due to their natural sound insulation. Consider room size, shape, and potential for acoustic treatment. b. Budgeting: Set a budget that covers all aspects, including equipment, seating, decor, and potential construction costs. c. Designing the Layout: Decide on seating arrangements that ensure all viewers have a clear line of sight to the screen. Plan for optimal speaker placement to achieve a surround sound effect. 2. Acoustic Treatments and Soundproofing a. Soundproofing: Use soundproof materials for walls, ceilings, and floors to prevent noise from entering or leaving the room. Consider installing heavy doors and sealing gaps to enhance sound isolation. b. Acoustic Panels: Add acoustic panels to walls and ceilings to manage sound reflections and improve audio clarity. Carpeting or rugs can also help absorb sound. 3. Equipment Selection a. Display: Choose between a large TV or a projector and screen. Projectors provide a more authentic cinema feel but require a darker room. Ensure the display supports high-resolution formats like 4K and HDR for the best
