Precise and efficient digital integration technology, like the wisdom center of the audio world, can process complex digital audio signals quickly and accurately, without missing any subtle audio information. It complements the analog circuit design with excellent sound quality. The analog circuit has accumulated exquisite craftsmanship and unique design for nearly 20 years, giving the sound a high degree of restoration without losing its delicate and textured characteristics. The constant current driving capability of the fully discrete Class A headphone amplifier injects powerful power into the entire audio system. It is like a high-performance direct injection engine, with its low distortion and high linearity advantages, creating a high combination of real sound and surging driving capability. This combination allows every note to be presented in the purest posture, whether it is the silky string vibrato in the melodious classical melody, or the shocking drum beat rhythm in the passionate rock music, it can be accurately restored and powerfully driven, bringing users the ultimate auditory feast as if they were at the music scene.

With the self-programmed FPGA digital shaping program as the core and multiple active crystal oscillator matrix modes, a full-range high-precision real-time audio transmission system has been developed. The self-developed USB, optical fiber, coaxial, and Bluetooth interfaces, as well as the synchronous reading and transmission of information and audio streams, give the M5 the ability to control the entire audio data stream. Each audio stream will establish a precise isochronous clock based on its sampling rate, and then be digitally integrated and transmitted to the digital-to-analog conversion system.
FPGA and dual active low phase noise audio clock build the core of the high precision digital domain. The corresponding clock system is called according to the sampling rate of the audio data stream of each input interface at the front end, and then the high-quality signal after digital shaping of the audio stream is transmitted to the digital-to-analog conversion system.
It supports high-precision asynchronous transmission signals and, with a dedicated 12MHz active data clock, transmits the synchronous audio signals of the FPGA on demand without missing any details.
Supports up to DSD512，PCM 768kHz，MQA 8X
It supports high-quality audio transmission such as AAC and LDAC, and with a 26MHz active data clock, it combines the Bluetooth transmission mode and the audio sampling rate to match a more precise audio mode, allowing the Bluetooth system's audio transmission to meet HiFi digital requirements.
We use the powerful programming capabilities of FPGA to enable M5 to achieve digital reception capabilities. It supports SPDIF digital protocol, not only that, we have added DSD64 (DoP)receiving capability in SPDIF
TempoTec has nearly 20 years of experience in audio analog circuit design. In the design of the March M5, we abandoned the traditional method of single-chip op amp inversion to generate balance, and adopted a luxurious dual-chip design. Dual AK4493SEQ is responsible for decoding and preliminary processing of digital signals. A single decoding chip is responsible for one channel, and the left and right channels have completely independent analog signals. These analog signals are then passed to the dual LME49720NA for amplification. In this process, since both chips have the characteristics of low distortion and high fidelity, the entire signal processing process is like a sophisticated audio production line. Every link ensures that the quality of the audio signal is not damaged, and minimizes the loss and distortion of the signal during the conversion and amplification process.
Independent designed left and right channels support DSD512 native, PCM 768kHz
Four outputs
6.35 mm single ended headphone port
4.4mm balance headphone port
The March M5 uses a four-way fully discrete Class A amplifier circuit in its headphone amplifier system design. The biggest advantage of the Class A amplifier circuit is that it can provide stable constant current output capability. When the headphone system plays large-scale music, due to its rapid dynamic changes, the headphone system needs to continuously and rapidly change the power requirements, which places high demands on the transient response capability of the headphone amplifier output. However, Amplification and decoding integrated chip can’t respond quickly due to their own design characteristics. The constant current capability of the Class A amplifier solves this problem. No response is required, and the current is always there.
4.4mm Balance output power is up to 1750mW+1750mW
March M5 uses a customized dual-output power module with an op amp power supply noise suppression circuit and a dedicated audio filter capacitor to provide clean energy for the digital-to-analog amplifier circuit. The power module inputs AC 110V~220V and outputs DC ±15V power to OPA-chips.
