TOPPING E70 Velvet｜High-Performance DAC Decoder with AK4499EX Flagship Chip

Born for Pure Sound Quality, Unveiling Every Detail of Music

The TOPPING E70 Velvet is a high-performance DAC decoder, featuring AKM's flagship AK4499EX DAC chip and the XMOS XU316 USB processor, supporting high-resolution audio formats up to DSD512 and PCM 768kHz. Its core features the latest QCC5125 Bluetooth chip, supporting LDAC Bluetooth transmission, allowing wireless audio to reach Hi-Res levels. Furthermore, the E70 Velvet is not just a pure decoder, but also features high-quality preamplifier functionality, capable of directly connecting to power amplifiers or active speakers.

Compared to most DACs that only offer basic decoding, the E70 Velvet, with its independent low-noise reference voltage power supply design and preamplifier function, provides a cleaner sound background and more flexible system compatibility. Whether for traditional Hi-Fi systems or modern PC-Fi desktop audio, it can serve as the central hub for sound.

Users whose audio system relies entirely on analog sources and do not need digital-to-analog conversion functionality.

TOPPING E70 Velvet Core Technologies and Features

AKM Flagship AK4499EX DAC Chip: Utilizes AKM's latest VELVET SOUND™ technology, delivering extremely low distortion and noise, presenting a silky smooth, richly detailed sound, with Total Harmonic Distortion plus Noise (THD+N) as low as 0.00006%.
XMOS XU316 USB Processor: Equipped with a 16-core XMOS XU316 processor, providing powerful processing capabilities and stable USB connectivity, supporting high-resolution audio decoding up to DSD512 and PCM 32bit/768kHz.
High-Resolution Bluetooth 5.1 Transmission: Built-in latest Qualcomm QCC5125 chip, supporting multiple high-resolution Bluetooth codecs such as LDAC, aptX Adaptive, aptX HD, AAC, and certified by Hi-Res Audio Wireless, allowing for excellent sound quality even with wireless connections.
Low-Noise Reference Voltage Power Supply: A new low-noise reference voltage power supply specifically designed for the AK4499EX, effectively filtering out power supply noise, suppressing noise levels below 1.3uVrms, providing a pitch-black sound background.
Multi-functional Preamplifier Mode: In addition to the fixed-level output mode for pure DAC use, the E70 Velvet also features a preamplifier mode, allowing precise volume adjustment from -99dB to 0dB, capable of directly driving power amplifiers or active speakers.
Selectable Balanced and Single-Ended Outputs: Offers XLR balanced output and RCA single-ended output, allowing users to choose between XLR only, RCA only, or both simultaneously, adapting to various complex audio system configurations.
12V Trigger Interface: Equipped with 12V Trigger In/Out ports, allowing power linkage with other devices featuring this function (e.g., TOPPING L70 headphone amplifier), enabling one-button synchronized power on/off, enhancing ease of use.
Smart Auto On/Off: The E70 Velvet can automatically detect valid input signals. When a signal is detected, it will automatically power on and switch to that source; if no signal is input for 1 minute, it will automatically enter standby mode.

Preamplifier Function (Preamplifier Mode)

In addition to the fixed-level output DAC mode, the E70 Velvet can also switch to preamplifier mode.
In this mode, you can precisely control the output volume from -99dB to 0dB using the front panel knob or the included remote control.
This feature allows the E70 Velvet to directly connect to power amplifiers or active monitor speakers, saving the budget and space for an additional preamplifier.

High-Resolution Bluetooth 5.1 Wireless Transmission

Utilizes the latest QCC5125 Bluetooth 5.1 chip, supporting mainstream audio codecs such as LDAC / aptX-Adaptive / aptX HD / aptX / AAC / SBC.
To pursue ultimate sound quality, the E70 Velvet bypasses the QCC5125's built-in DAC, directly sending its digital signal to the core AK4499EX for decoding, ensuring optimal reproduction of wireless audio.
Certified by Hi-Res Audio Wireless, providing a stable and high-quality wireless listening experience.
