Frequently Asked Questions

Foshan ShuangMuSanLin Electronics, also known as SMSL, was founded in 2009 in Shenzhen, China. The company specializes in audio DAC, stereo headphone amplifiers and power amplifiers. Consider the SMSL SA-98E to drive your speakers if you need a ton of power in a small space. The SMSL SA-98E is designed around the TDA7498E amplifier chip from STMicroelectronics and is built with high-quality electronic components from Panasonic, ALPS, WIMA and Siemens. Although this amplifier is small in size, it produces no less than 160 watts per channel. The SMSL SA-36A Pro is the perfect amplifier to drive small to medium-sized loudspeakers in a near-field listening environment. Centered on the STMicroelectronics TDA7492, this Class-D amplifier is highly efficient while providing the listener with deep bass and an expansive soundstage. The SMSL A8 and SMSL A6 are multifunction amplifiers and built around the ICEpower 125ASX2 and the 50ASX2 respectively. They have a built-in DAC, phono preamp and headphone amplifier. The SMSL Q5 Pro has the same great sound and features of the original Q5, but adds a micro USB input and a subwoofer output. A 192 kHz/24-bit sample rate, a multitude of input methods and the isolated speaker binding posts make the Q5 Pro a high-quality amplifier/DAC combination.

 

 

 

SMSL DAC

The SMSL AD18 uses a DAC that features zero phase shift, a strong anti-inference capability thanks to the digital CS8422 receiving chip. The signal then goes into the TAS5508C chip for digital sound processing and pre-amplification. This then sends it to the highly efficient (90%) TAS5342A chip, boosting the output to 80 Watts per channel. It features NFC and Bluetooth 4.2 wireless connectivity and also supports your favorite wired inputs: AUX, 3.5mm coaxial, optical and USB. The SMSL M8A is the upgraded version of the M8 with higher quality components to dramatically improve the sound quality. Part of the upgrade was the addition of a special OPAMP to replace the standard NE5532 chip. This gives SMSL M8A a more tubular sound with warmer mids to combat listening fatigue. As a flat portable DAC/amp, the SMSL IQ is best combined with laptops or smartphones and high-end IEMs. It uses well-regarded components to deliver accurate, reference-quality sound. The SMLS IQ has a small OLED display on the left. For users with balanced IEMs, it has a 2.5-millimeter balanced output in addition to the 3.5-millimeter unbalanced output.

The amplifier works in the same way as the record amplifier and amplifier modules. To operate the speaker, the amplifier receives the line level signal and increases the capacitance level. Amplifiers usually have inputs and outputs, power connections, various settings, specifications and various connections, such as Bluetooth, Ethernet, NFC, streaming services, XLR and Wi-Fi. At Your@udio you buy amplifiers from high-end brands such as SMSL and Your@udio

 

 

 

Watts per channel (WPC) of amplifiers

While most amps are relatively efficient, they have significant watts per channel (WPC) differences. SoundImports supplies amplifiers in watts per channel (WPC) ranging from 15 WPC to 50 WPC, up to 100 WPC or even 1000 WPC! By copying frequencies from 20 to 20,000 Hz, the amplifier tries to cover the entire range of human hearing and music. To drive the speaker, the amplifier passes the signal at the line level and increases the capacitance level. In addition, the amplifier is equipped with inputs and outputs, power links and multiple controls.

 

 

 

What can you do with an amplifier?

The amplifier's digital divider allows the end user to filter the active point by isolating the high-frequency signal from the amplified signal. The amplifier usually accepts all line and speaker signals and then routes these signals to the speakers. Many amplifiers have phase or delay control to control the signal as best as possible. The amplifier has a digital divider that allows the end user to adjust the effective point of their divider by removing higher frequencies from the amplified signal. Unlike amplifier modules, regular amplifiers do not require DSP modules. The reason is that most people use amplifiers to amplify the original signal and listen to the "output". However, other users prefer to add lower frequencies to boost the bass. This requires a DSP module, especially if users are interested in building their own speakers and need to optimize or refine the output.

 

 

 

Types of Amplifiers

SoundImports offers different types of amplifiers, such as stereo 2-channel amplifiers and multi-zone amplifiers, plate amplifiers and amplifier modules. MiniDSP SHD Power is an excellent single amplifier with Dirac live DSP option as software. This MiniDSP amplifier delivers the power it deserves for home entertainment systems. When impressive performance and reliability are required, many professional integrators and installers rely on this MiniDSP amplifier. For computer workstations, small home theater setups and studio monitors and DJ workstations, this is an inevitable element!

Whether it's the legacy audio system from the 1960s or the new analog high-fidelity system, at some point everyone wants to play digital signals on the analog system. A good example is the purchase of new TVs - large format, clear images and ultra-thin TVs. This sleek design usually comes at the expense of audio quality. But if you already have a new TV sound system, why buy an extra sound system? A flat screen TV plus analog hi-fi system is one of the main uses of small digital-to-analog converters. Most modern devices are already equipped with a built-in DAC module. The DAC module takes the digital signal and converts it into an analog signal.

 

If most devices already have a built-in DAC module, why do you need an external one? For the same reason, even if there are pre-assembled speakers on the market, audiophiles will make their own speakers - different manufacturers use inferior components. While smartphones can do many things well, audio is not one of them, for example. Stand-alone devices can only do one thing by design, so they are excellent at converting digital signals.

 

 

What types of DAC modules are there? At Your@udio you will find the USB DAC module, the headset DAC module and the multimedia DAC module. In any case, the USB and earphone DAC modules can usually be easily installed in a bag or used with earphones, which can greatly improve the audio output of the device. The multimedia DAC module is a larger device designed for desktop and home theater applications. These usually require the equipment to be stationary and part of a more complex setup.

Loudspeakers come in different sizes. The best floorstanding speakers are often regarded by experts as the best-presenting type. Due to their large build and better drivers (the separate speakers in the housing), column speakers often sound much better than bookshelf speakers. But that is often only an option if you have enough space for it. In smaller living rooms, a more compact speaker set can sound just better. Do you miss the low tones with bookshelf speakers? If your hi-fi set contains an amplifier with a sub or pre-out output, you can add an extra subwoofer. This is a special speaker that only produces the low tones, in addition to the small speakers. Adding a subwoofer is an upgrade that can make a lot of difference in terms of sound.

 

There is also an intermediate form: stand-mount speakers. They are more compact than floorstanders but are too large to simply place on a piece of furniture or shelf. Usually you have to place them on a speaker stand.

 

Speakers must match your stereo. Check whether your amplifier is suitable for the number of ohms of your speakers. You can often find that specification at the back of the speaker or on the manufacturer's website. It is important that you do not connect speakers with a low value (for example 4 ohms) to an amplifier with 8 or more ohms.

 

Speakers are also classified based on the amount of built-in speakers or drivers. 2- or 3-way is common. In addition to drivers, loudspeakers often also have passive woofers and bass ports or reflexes. These solutions ensure that speakers spread more low tones. Keep in mind that a bass port (a hole in the housing) at the back will provide more or less bass if the speaker is closer or further from the wall.
