1. INSTALLATION'&'SAFETY'INSTRUCTIONS'
This STREAMER is designed and built to provide trouble-free performance, but as with all
electronic devices it is necessary to observe a few precautions:
• Unpack the STREAMER carefully.
• Position the STREAMER on a stable, horizontal surface, i.e. sturdy rack.
• The STREAMER supports voltage 100-250VAC worldwide voltage by a voltage
selector. The voltage selector can be found at the bottom of the STREAMER. Switch
it to the correct voltage prior to powering it up, i.e. 115V for the US / 230V for the
EU.
• Please connect the AC power cord with earth(ground) pin unless it is absolutely
required to reduce hum from the ground loops of the connected devices.
• Always ensure that when disconnecting and reconnecting your audio equipment the
mains supply is turned off.
• Position the power cord and signal interconnects where they are not likely cause trip
and fall hazard.
• Do not use the STREAMER near water, or place water-filled containers on the
STREAMER. Entry of liquid into the STREAMER is hazardous and may cause electric
shock and/or fire hazard.
• Do not place the unit under direct sunlight or heat source.
• Do not remove any covers or try to gain access to the inside. There are no user
adjustments or fuses to change without qualification.
• Clean regularly with a damp soft cloth. Do not use any cleaning agents as it might
damage the surface finishing.
• The electronics in modern hi-fi equipment is complex and may, therefore, be
adversely affected or damaged by lightning. For protection of the audio system
during electrical storms, disconnect the mains plugs.

3. DESIGN'HIGHLIGHTS'
3.1
ADAPTIVE FIFO BUFFER RECLOCKING
The DENAFRIPS approach to address the jitters issue by FIFO BUFFER RECLOCKING. The
adaptive FIFO buffer store the source digital audio data in the memory. These data are read
from the memory using the low phase noise, precision TCXO FEMTO Clock, located right in
the STREAMER.
This technology is close to the perfection, especially so with the local FEMTO Clock. The
jitter is so small that it can be neglected.
3.2
PROPRIETARY STREAMER MODULE
The ARCE STREAMER is equipped with a unique Streamer Module - developed by DENAFRIPS
engineer in-house - incorporating a Quad-Core AMR Cortex Processor, High Quality Crystal
Oscillators, LT Fast Transient Response, Low Noise, and LDO Regulators. Tailored Operating
System (OS) optimized to deliver a euphoric sound experience

STREAMER ARCHITECTURE
DIGITAL SIGNAL PROCESSING – The FPGA chip of this product is filled with DENAFRIPS'
extensive experience in Digital Signal Processing. Furthermore, the digital signals are
safeguarded through Galvanic Isolation using Opto-Couplers
FEMTO CLOCK – These data are read from the memory using the low phase noise, accurate
precision FEMTO Clock, located right in the STREAMER. The processed data are sent to the
final stage Discrete R-2R for DA conversion.
