本機特點
■裝置2系統的LINE輸入,也可透過按鍵或遙控器簡單操作。
■喇叭最大輸出20W + 20W(4Ω)。
■耳機最大輸出110mW(32Ω)。
■透過耳機Plug -in /out進行耳機與喇叭間的切換。
■耳機輸出使用OCL(Output・condenser・less),可明確的傳達聲音。
■採用electron volume(rotary encoder),可消除Gang error,享受高品味音質。
■可從聆聽位置利用專用遙控器選擇輸入模式、靜音、調整音量等。
■經由SMV(Smoothing-Volume)技術,可微幅調整音量,不像傳統類比般的急遽變化。
■音量按鍵周圍配置16轉式的LED,可輕鬆知道Volume大小。LED亦配合電源的開啟與關閉閃爍。

商品說明

Remote Control from Listening Position The size is small. But the remote control makes it possible to do the volume adjustement of the speaker and headphone, input source switch, mute ON/OFF aod LED display change from your listening position.


Separate ICs for Speaker and Headphone Outputs Traditional headphone volume is adjusted via the speakerphone output impedance. The sound quality is not good. Based on speaker impedance, the headphone volume is divided into left and right. The RDA-2022 uses seperate ICs for headphone and speaker outputs. The outputs are independent and the sound quality is better.


Headphone Terminal The headphone output is OCL (Output Capacitor-less), making the sound directly transmitted and as a result bring about crystal clear resolution. The built-in 6.5mm standard jack allows max. 110mW*110mW (32Ohms). The speaker output can be changed by the headphone plug in and out.


Electronic Volume Control (Speaker, Headphone) The motor drived analog volume is operated directly from the sound signal. As result, the right/left side volume is not stable and often results in gang errors. This device uses rotary encoder for electronic volume control and the volume up/down and left/right are balanced, users can enjoy high sound quality no matter what the volume is. Speaker Output Terminal The max. speaker output is 20W + 20W (4 Ohms). Gold-plated terminal is used, minimizing the sound detenoration. Compatible with naked wire, banana plug, and Y plug.


4-layer PCB Power andGND are on the inner layers. This makes the machine strongly resistant to noise. Even there is sharp volume change, ICs or parts can still firmly supply the power.


Anti Pop Noise Pop noise from speaker output is stopped by the compression circuitry. Noise from headphone output is blocked by the built in relay.


SMV (Smoothing-Volume) Technology The use of SMV (smoothing-Volume) technlogy makes it possible to micro adjust the volume and maintain it at a pleasant level without sharp change as will happen with the analog systems.


LED Volume Display Volume knob is surrounded with LEDs. When volume is changed, the LEDs will be displayed accordingly.
