Precautions

Read Carefully Before Proceeding
Please keep this manual in a convenient place for future reference.

Power Supply
Always use a DC 9V, center negative, 200mA AC adapter. Use of an adapter other than that specified could damage the unit or cause malfunction and pose a safety hazard. Always connect the AC adapter to an AC outlet that supplies the rated voltage required by the adapter.
Disconnect the AC adapter from the AC outlet when during lightning storms or not using the unit for an extended period.

Connections
Always turn off the power before connecting or disconnecting. Make sure to disconnect all cables and AC adapter before moving the unit. This will help prevent malfunction and damages.

Environment Considerations
Avoid using the unit in any of the following conditions that could cause malfunction:

  • Extremely hot or cold places;
  • Under direct sunlight;
  • Magnetic fields;
  • Near heaters and other heat sources;
  • Sandy or dusty places;
  • Places that are extremely humid or exposed to splashing water;
  • Places with lots of vibrations.

Electrical Interference
Devices that are very susceptible to interference or that emits powerful electromagnetic waves (e.g. radios and TVs) should not be placed near this unit, as interference could occur. Electromagnetic interference could cause malfunction and could corrupt or destroy data.
Always operate this unit at a suitable distance from these devices.

Handling
Do not apply excessive force to the switches and other controls, exposing the unit to strong impacts, which could cause it to break.
Do not put foreign objects or liquids into the unit.
Never open the case or attempt to modify the product in anyway since this can result in damage to the unit. Clean only with a soft dry cloth.

Main Features

Donner Soph Gate is an intelligent noise gate and effects loop pedal that gives you a noise-free and full dynamic performance. With the intelligent noise gate algorithm, it
can fully reduce the unwanted noise whatever you are using some distortion pedals or a high gain big noise amplifier. Threshold, Attack, Release, Hold and Return parameters help you set up your tone that easy to suit for all kinds of music genre. Send and return FX loop for patching noisy pedals or amplifier through or creatively sidechaining in other audio signals, provide you a satisfied noise cutting instrument playing solution. True bypass allows for optimum clarity and zero high-end loss. Once you are using Soph Gate, you will never want to remove it from your pedal board.

  1. DC IN: Input for power supply, use a 9V DC regulated power EB-C–0 supply 200mA, center pin negative.
  2. Threshold knob: Specifies the level at which the gate opens, controls how much level is needed to open the noise gate and allow your signal to pass through, rangefrom-60dB to O dB.
  3. Attack knob: Time that it takes for the gate to open fully once the threshold is exceeded, range from 0.5ms to 500ms.
  4. Hold switch: Controls the minimum amount of time that the gate must stay open after the threshold is exceeded, Quick=1ms, Slow=100ms.
  5. Return knob: Sets the difference between the threshold level that opens the gate and the level that closes it. Higher Return values reduce “chatter” caused
    by the gate rapidly opening and closing when the input signal is near the threshold, range from Od B to 20dB.
  6. Release knob: Time that it takes for the gate to fully close after the signal falls below the threshold, range from 10ms to 1000ms.
  7. Send: 1/4″ mono audio jack for connecting to the input of distortion pedal, amplifier, or the beginning of your effects loop to achieve sidechain.
  8. Return: 1/4″ mono audio jack for connecting to the output of distortion pedal, amplifier (preamp output), or the end of your effects loop to achieve sidechain.
  9. Output: 1/4″ mono audio jack, effect output for connection to amp or other devices.
  10. Input: 1/4″ mono audio jack for connecting to the input device or instrument.
  11. LED: Indicates the effect on/off and the gate open or close.
  12. Footswitch: Engages and disengages the effect and sidechain.

Setup Instruction

Notes: Stomp Box sidechain setup is designed for setting the noisy distortion pedal at the sidechain in order to reduce the gain noise but also can set the threshold in a low position. It can keep your high gain tone without noise gate tone losing. Please remember turn on the Soph Gate to get your high gain tone. When the Soph Gate is turned off, there will only the clean signal go through your chain.

Sidechain Setup (4 cable method with Amp):

Donner PD12 Intelligent Noise Gate and Effects Loop Pedal Owner's Manual - Sidechain setup

Notes: 4 cable method sidechain setup is designed for the high gain amp when using the high gain channel. It can reduce the amp noise like “hum” and “Sissie” and keep your amp tone. Please remember turn on the Soph Gate to get your high gain tone. When the Soph Gate is turned off, there will only the clean signal go through your chain, means it will pass your chain signal to the power amp part.

Guide:

  1. Connect the power, use a 9V DC regulated power supply EB-C–0 more than 200mA. center pin negative.
  2. Connect your instrument amp and pedal as listed above.
  3. Press the On/Off button to turn on Soph Gate. Recommend you start with THRESHOLD, ATTACK, RETURN and RELEASE set to its minimum position. Turn up the volume knob on your guitar but hold the strings to stop any feedback. You should hear noise coming through your amplifier. Turn up the THRESHOLD knob until the noise disappears, then continue to turn it up just a little more; this setting makes for a good starting point.
  4. Play some riffs or solo, adjust the A TT ACK and RELEASE to set the gate opening and closing time. Also you should adjust the HOLD switch to set the hold time to get your comfortable position.
  5. When you hear “chatter” caused by the gate rapidly opening and closing, turn up the RETURN to get smooth tone tail.
  6. Enjoy your playing.
