Q&A

X-SABRE Pro

A: Yes, X-SABRE Pro has digital volume control function, and you can optionally turn on the +18dB gain.
A: X-SABRE Pro is a pure DAC, it only have 1 pair of XLR output and 1 pair of RCA output, no headphone output. If you want to set an X-SABRE Pro as an audio source of your headphone Hi-Fi system, you also need a headphone amplifier.
A: The IIS, also can be expressed as I²S (Inter-IC Sound), is an electrical serial bus interface standard used for connecting digital audio devices together. It is the high-speed channel of audio stream between ICs. The IIS port has the same shape with HDMI port, but using the PS Audio’s pin definition. So X-SABRE Pro support all the devices which has PS Audio standard IIS output. It does NOT support regular HDMI connection, please don’t try to connect your X-SABRE Pro to non-IIS output devices.
A: The XLR and RCA of X-SABRE Pro can output at the same time. No matter it output simultaneously or respectively, the parameters (SNR, THD+N, crosstalk etc.) of outputs are the same as we declared in the specifications.
A: Once the X-SABRE Pro connected to the power, there will be 5 seconds initializing process. In this period, your X-SABRE Pro will not respond to any operations, the power LED is light up, till the red LED indicator turn off, then you can turn the DAC on.
A: There is 1 ES9038PRO D/A chip in an X-SABRE Pro. ES9038PRO is a high performance 32-bit 8-channel DAC, we use each 4 D/A units process 1 channel audio stream, which constructed the 8 mono to stereo structure. So it’s no need to use more ES9038PRO chips in X-SABRE Pro.

QUATTRO II

A: Yes, all the digital input can support DSD signal, USB input support up to DSD256, the rest of digital input support up to DSD64.
A: It is output at same time, you can connect two headphones on it at same time.
A: You can download the configuration guide from our official website.
A: Yes, they are output at same time.
A: It can be set under the “PRE” mode.
A: It has the PRE function, setting from the configuration menu, and it can increases the line output to up +10dB, easy to connect the active speaker.
A: The customer can update the firmware of XMOS, MCU, and FPGA via the USB port.
A: There will have less than 1W power consumption under the standby status.

Mini-i Pro 2 (Mini-i Pro 2S)

A: Yes, Both of Mini-i Pro 2 and Mini-i Pro 2S have digital volume control function, But the max volume of Mini-i Pro 2 is 0dB, the Mini-i Pro 2S can be configured to +18dB optionally.
A: The Mini-i Pro 2 uses ES9016S D/A chip, and the Mini-i Pro 2S uses ES9026PRO D/A chip;Mini-i Pro 2‘s max volume is 0dB, and the Mini-i Pro 2S is +18dB; Mini-i Pro 2 has only 2 kinds of PCM filters, the Mini-i Pro 2S has 7 kinds of PCM filters; DSD audio stream only supported vis USB port in Mini-i Pro 2, but in Mini-i Pro 2S, in addition to the USB port, the coaxial, optical and AES/EBU also can support DSD audio stream (DSD64 DoP).
A: When the headphone connected to Mini-i Pro 2 (Mini-i Pro 2S), the lineout would turn off automatically.

Mini-i AMP

A: There will be better performance when the Mini-i AMP connected with loudspeakers which impedance is 4~8 ohms and the sensitivity is higher than 85dB. If your loudspeakers’ sensitivity is very low, we suggest you buy 2 Mini-i AMPs to establish the BTL system.
A: The Mini-i AMP is a pure power amplifier, not an integrated amplifier, so you need a pre-amplifier to adjust the output level, or your audio output devices can adjust output volume directly.

HPA-3U⁺

A: The line output will be auto muted when the headphone plug is inserted.
A: HPA-3U⁺ can drive the headphones between 30-600 ohms.
A: There are three levels of gain can be adjusted on the front panel.
A: It's normal, because the HPA-3U⁺ is a class A headphone amplifier, it will hotter after working for a while.
A: The HPA-3U⁺ is upgraded from HPA-3U, the HPA-3U⁺ changed the USB module, uses CS4398 D/A chip, which support up to iBit/5.6MHz DSD audio stream, and the SNR and THD+N are promoted.

HPA-3B

A: Yes, you can connect two headphones on it at same time.
A: There have three levels gain can be adjusted on the rear panel.
A: HPA-3B can connect with the single-ended input via the converter which is in the accessory of HPA-3B.
A: This 4-pins balance headphone output jack is a standard port, it can work with all kinds of headphones which use 4-pins balance headphone jack.
A: It is normal, because the HPA-3U is an A class mode headphone amplifier, so it will be hotter after working for a while.

X-SPDIF

A: The internal digital transformer to make USB port isolates the SPDIF output.
A: Support Windows OS, Mac OS and some versions of Linux OS.
A: The internal chip is the XMOS asynchronous transmission chip.

RM2

A: Compared with RM1, RM2 increased four buttons for each channel; you can directly select any channel.
A: The same as the definition button code of RM1; It’s fully compatible and can be used directly.
A: Yes it can, but the previous machines which are selling with RM1 will not respond for the new keys of RM2.
A: Use a CR2032 battery and can be used about 1 year after replace a new battery, you can replace the battery when it runs out.

General Questions

A: The latest Matrix driver is version 3.40, there are 3 folders in the RAR file, you can choose the driver in the right folder according to your operating system. Some of the Windows 7 users failed to install the driver, please make sure your Windows 7 was installed Service Pack 1 and KB3033929 security update.
A: Yes, you can set the appropriate voltage range on the side (bottom) of the product, there are two sections of 100V-110V and 220V-240V can be chosen.
A: The USB port of Matrix products, only use as data connection (X-SPDIF is not included), the power supply comes from the built-in toroidal transformer, so it’s no need to add external USB power supply or power cleaning devices for Matrix products.
A: Matrix products compatible with Mac OS 10.6.4 or later, and Windows XP or later. You also can connect your Matrix products to your iOS devices via Apple Lightning to USB Camera Adapter, or to most of android devices via USB OTG cable.
