Remote control

Install 2 x AAA batteries as instructions. When using the remote control, point it toward the remote control signal receiver on the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between the main unit and the remote control. The remote control might not work if the remote control signal receiver on the unit is exposed to direct sunlight or bright light. If this occurs, try moving the unit. Beware that the use of this remote control could cause the unintentional operation of other devices that can be controlled by infra.

Operating the remote control

Note
This remote controller uses 2 x R03/AAA batteries.

• COA (Coaxial input)

Function introduction

PCM FILTER

• FL1 (Fixed minimum phase fast roll-off)
• FL2 (Linear slow roll-off)
• FL3 (Apodizing Apodization Filter)
• FL4 (Minimum phase fast roll-off)
• FL5 (Minimum phase slow roll-off)
• FL6 (Linear fast roll-off)
• FL7 (Brickwall Mixing Filter)

DPLL

• DPLL 1-9, the lower the value, the smaller the clock jitter.
• This DPLL setting is a unique function of ESS series products.
• It can adjust the bandwidth of the DPLL digital phase-locked loop circuit inside the chip so that the chip can achieve a balance between anti-clock utter and input tolerance

Effect

• When the clock stability of the input signal is good, this value can be reduced, so that the clock performance of the system is better
• When the clock stability of the input signal is not good, the sound may be interrupted. Increasing this value can avoid the occurrence of audio interruption! Especially when using V as the signal source
• USB MODE
• UACI

(USB1.1 description: When USB1.1 is selected, the WIN system is free of drive, and supports sampling rate 44.1-96kHz, 24bit)

• UAC2 (select USB2.0, WIN system needs to install driver, support DSD)
• BRIGHTNESS
• bi1-5
