BLEND控制旋钮允许用户将一些原始的未经压缩的信号按一定比例混合至OUTPUT输出信号中。当效果器设置在高压缩度时，如果原音的音头仍然能在长延音中听到，可以通过这个旋钮来进行调节。请注意当增大此设置时，相应的压缩信号和VOLUME音量也会增大。当增大BLEND信号时，有必要将VOLUME音量控制减小来保持整体信号水平与直通模式下匹配。VOLUME音量控制位于音频信号路径末端，为压缩模式下整个输出信号的总音量控制。

经我们很荣幸地为大家呈现我们首款光耦电路压缩效果器OC-1，本产品不只限于吉他设备的使用。

最小化所有控制设置不会产生压缩效果和输出提升。

如果延音（sustain）过大，请减小COMP的设置，并同时调整VOLUME音量设置来匹配直通模式下水平

如果需要更多的延音（sustain），请将COMP设置增大至50%之上，并且相应增加VOLUME水平来匹配直通模式下音量。

Many years in the development, we are proud to present our first Optical Compressor: designed specifically for, but not limited to, guitar.

In common with our recently introduced CC-1, the OC-1 is a completely original design, not copied from any previous or current device.

A Feed-Forward design, the OC-1 features a minimized two stage audio signal path: input buffer and output make-up gain: this ensures no change to frequency response, no distortion and the absolute minimum of added noise. Between the two audio sections is a light controlled variable attenuator driven with a control current generated by the Side Chain. All signal monitoring and gain reduction drive circuits that are separately routed via a six stage Side Chain: these signals do not pass through the audio circuits and thhus cannot degrade the audio performance.

Operation is straight forward:
Connect guitar using screened cable to the OC-1 INPUT
Connect OC-1 OUTPUT using screened cable to your amp input
With OC-1 in bypass mode set guitar volume and tone to 100% (maximum)
Set amp volume and tone to suit normal playing level
Set all OC-1 controls to minimum (fully counter clockwise)
Engage OC-1 and note that the signal level and tone as the same as when in bypass mode IE: minimum settings create no compression or output boost
Increase the COMP (compression) control to approximately 50% (12 o'clock) while playing and note the decrease in output volume and increased sustain. Increase the VOLUME in small increments until the output level matches the bypass level - compare by switching back and forth between bypass and OC-1
If the sustain is too great reduce the COMP setting and also the VOLUME to again match the bypassed level
If more sustain is required increase the COMP setting above 50% and make corresponding increases in VOLUME to again match the bypassed level. Actual settings will be dependant on pickup signal level, playing style and of course, personal preference

A further feature has been added: BLEND. This control allows you to add a small percentage of the original, uncompressed signal to the OUTPUT. This is particularly useful when very high compression settings have been dialed in, as a controlled amount if the original attack can still be heard through with the long sustain. Please note that the control increases in relation to the compressed signal as the VOLUME is increased. When adding the BLEND signal it will be necessary to reduce the VOLUME to maintain the overall signal level to match the bypassed level. The VOLUME control is at the very end of the audio path and is a master volume of the whole of the output signal in compress mode.

The OC-1 would normally be the first device the guitar "sees" thus maintaining signal level more constant.
