MASSIVE TRANSFORMERS｜大型變壓器
XR 系列以一個大型環形變壓器為核心所構建。
這為擴大機中的電子電路提供平穩且一致的功率，並產生穩定的輸出電流，即使在交流電可能產生波動的環境中亦是如此。
XR series are built around a massive heavy-duty toroidal transformer.
This delivers smooth and consistent power into the amplifier electronic circuits, resulting in stable and reliable output power, even in environments where AC may fluctuate.
PROTECTION｜保護裝置
XR 系列擴大機具有全面的電路保護機制。這可避免無論外部電纜、交流電源或揚聲器產生的問題導致擴大機損壞。
前面板 LED 指示燈可對問題提供即時且清晰的反饋。
如發生外部故障，紅色 LED“故障”燈將亮起，擴大機將進入保護模式，當故障排除時，按下後面板上的“復位”按鈕即可消除故障燈號。
前面板上黃色的“過載”LED指示燈號，表示輸出產生過載導致聲音失真，此時應適當減小音量旋鈕的增益以避免揚聲器損壞。
An XR series amplifier features comprehensive protection circuitry. This ensures that no matter what problems might exist with external cabling,
AC power or loudspeakers, the amplifier will protect itself, and its surroundings.
Front panel LED’s give immediate and clear feedback to the situation. Should an external fault occur, the red LED ‘Fault’ light will illuminate and the amp will go into Protection mode. A rear panel ‘Reset’ button is then available to reset the amplifier once the external fault has been diagnosed and removed.
Handy ‘Clip’ LED’s are also visible from the front panel. Even from a distance, its simple and clear to see and understand the status of the amp.
A LOOK BEHIND THE SCENES｜機背面板
XR 系列擴大機的機背配置了2組XLR (平衡輸入/輸出連接埠)，用以連接前級或多台擴大機。
立體聲模式 (兩個通道獨立工作)｜橋接單聲道模式 (CH1 輸入信號進入 BRIDGE 輸出連接埠)｜並聯單聲道模式 (CH1 輸入信號同時進入 CH1 和 CH2 輸出連接埠)， 可透過切換開關進行控制。
輸入靈敏度開關可在 0.775v 或 1.4v 之間進行選擇。
Around the back of the XR are the balanced inputs and outputs along with configuration switches.
A handy feature are the 2 x XLR link outputs which allow for easy ‘daisy chaining’ of multiple amps – removing the need for external patching or excessive cabling.
Around the back is also the input sensitivity switch selectable between 0.775v or 1.4v.
The main ‘Bridge / Stereo / Parallel’ mode switch is also on the rear. STEREO mode makes the two channels work independently. CH1 input signal goes to CH1 output and CH2 signal goes to CH2 output. BRIDGE mode makes CH1 input signal go to the BRIDGE output socket. This is controlled by using the CH1 volume control. PARALLEL mode makes CH1 input signal go to both CH1 and CH2 output sockets. The input socket of CH2 has no effect. The channel volumes can be adjusted independently.
