Introduction

Congratulations! You have purchased a state-of-the-art mixing console that sets new standards. In combination with its comprehensive range of features and pro-level connections, the machine will be your perfect tool for any kind of application: broadcasting, video dubbing or giving the sound of your band its finishing touch.

Before You Begin

Your machine was carefully packed in the factory and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit. If the unit is damaged, please do not return it to our company, but notify your dealer and the shipping company immediately, otherwise claims for damage or replacement may not be granted. Shipping claims must be made by the consignee. Be sure that there is enough space around the unit for cooling purposes and to avoid overheating. Please do not place your mixing console on high-temperature devices such as radiators or power amps.

Control Elements and Connectors

1. MIC/LINE: Accepts XLR and 1/4 connectors. Connect microphones or instruments.
2. PHANTOM/+48V LED: When the phantom power of the channel is turned on, the red +48V light is on.
3. TRIM: Use the TRIM control to adjust the input gain. This control should always be turned fully counterclockwise whenever you connect or disconnect a signal source to one of the Inputs.
4. LOW CUT: In addition, the mono channels are equipped with a steep LOW CUT filter (slope at 18 dB/Oct., -3 dB at 75 Hz) designed to eliminate unwanted low-frequency signal components.
5. EQ: The upper (HIGH) and the lower band (LOW) are shelving filters that increase or decrease all frequencies above or below their cut-off frequency. The cut-off frequencies of the upper and lower band are 12 kHz and 80 Hz respectively. The mid band is configured as a peak filter with a center frequency of 2.5 kHz.
6. CLIP LED: The CLIP LEDs of the mono channels illuminate when the input signal is driven too high, which could cause distortion. If this happens, use the TRIM control to reduce the preamp level until the LED does not light anymore.
7. FX: The FX sends enable you to feed signals via a variable control from one or more channels and sum these signals to a bus. The bus appears at the console’s FX send output and can be fed from there to an external effects device. The return from the effects unit is then brought back into the console on the stereo channels. Each FX send is mono and features up to +10 dB gain.

Product Usage Instructions

1. Connect your microphones or instruments to the MIC/LINE input using XLR or 1/4 connectors.
2. Activate the phantom power for condenser mics using the PHANTOM/+48V switch. The red +48V light will turn on.
3. Use the TRIM control to adjust the input gain. Turn it fully counterclockwise when connecting or disconnecting a signal source.
4. If using mono channels, you can apply a steep LOW CUT filter by using the LOW CUT control. This eliminates unwanted low-frequency signal components.
5. The EQ controls allow you to adjust the frequencies of the upper (HIGH) and lower band (LOW) using shelving filters. The cut-off frequencies are 12 kHz and 80 Hz respectively. The mid band is configured as a peak filter with a center frequency of 2.5 kHz.
6. Pay attention to the CLIP LED on the mono channels. If it illuminates, it means the input signal is too high and could cause distortion. Adjust the TRIM control to reduce the preamp level until the LED no longer lights up.
7. Use the FX sent to feed signals from one or more channels to a bus. Adjust the FX send level using the FX control. The bus output can be connected to an external effects device. The return from the effects unit should be connected to the stereo channels on the console.

Control Elements and Connectors

1. MIC/LINE: Accepts XL and 1/4″ connectors. Connect microphones or instruments. The phantom power required for condenser mics can be activated with switch PHANTOM.
2. PHANTOM/+48V LED: When the phantom power of the channel is turned on, the red +48V light is on.
3. TRIM: Use the TRIM control to adjust the input gain. This control should always be turned fully counterclockwise whenever you connect or disconnect a signal source to one of the Inputs.
4. LOW CUT : In addition, the mono channels are equipped with a steep LOW CUT filter (slope at 18 dB/oct., -3 dB at 75 Hz) designed to eliminate unwanted low-frequency signal components.
5. EQ: The upper (HIGH) and the lower band (LOW) are shelving filters that increase or decrease all frequencies above or below their cut-off frequency. The cut-off frequencies of the upper and lower band are 12 kHz and 80 Hz respectively. The mid band is configured as a peak filter with a center frequency of 2.5 kHz.
6. CLIP LED: The CLIP LED’s of the mono channels illuminate when the input signal is driven too high, which could cause distortion. If this happens, use the TRIM control to reduce the preamp level until the LED does not light anymore.
7. FX: The FX sends enable you to feed signals via a variable control from one or more channels and sum these signals to a bus. The bus appears at the console’s FX send output and can be fed from there to an external effects device. The return from the effects unit is then brought back into the console on the stereo channels. Each FX send is mono and features up to +10 B gain.
8. PAN: The PAN control determines the position of the channel signal within the stereo image. This control features a constant-power characteristic, which means the signal is always maintained at a constant level, irrespective of position in the stereo panorama.
9. LEVEL: The LEVEL control determines the level of the channel signal in the main mix.
10. LINE IN: Each stereo channel has two balanced line level inputs on 1/4″ jacks for left (L/MONO) and right (R) channels. If you use only the (L/MONO) jack, same sound is output from both left and right speakers.
11. FX SEND: The FX SEND connector outputs the signal you picked up from the individual channels using the FX SEND controls. You can connect this to the input of an external effects device in order to process the FX bus master signal. Once an effects mix is created, the processed signal can then be routed from the effects device outputs back into a stereo input.
12. PHONES: The stereo PHONES jack (at the top of the connector panel) is where headphones are connected. The unbalanced CTRL ROOM OUT jacks carry the summed effects and main mix signals, as well as soloed channel signals. The PHONES/CONTROL ROOM control in the main section adjusts the level of both headphones and main monitor outputs.
13. CTRL ROOM OUT: The unbalanced CTRL ROOM OUT jacks carry the summed effects and main mix signals, as well as soloed channel signals. The PHONES/CTRL ROOM control adjusts the level of both headphones and main monitor outputs.
14. MAIN OUT: The MAIN OUT connectors are balanced mono jacks. The main mix signal appears here at a Level of 0 Bu. The MAIN LEVEL adiusts the volume of these outputs.
    REC OUT: These connectors are wired in parallel with the MAIN OUT and carry the main mix signal (unbalanced). Connect the REC OUT to the inputs of your recording device. The output level is adjusted via MAIN LEVEL.
    AUX IN: The AUX inputs are used to bring an external signal source (e.g. CD player, tape deck, etc.) into the console.
    +4-10: The stereo inputs have an input sensitivity switch which selects between +4 Bu and – 10 dBV. At – 10 dBV (home-recording level), the input is more sensitive (requires less level to drive it) than at +4 dBu (studio level).

Digital Effects Processor section

PROGRAM control
The effect processor consists of 24 PCS effect types. Turn the program/parameter knob to adjust the serial number of the effect. The led digital tube flashes during the adjustment. After adjusting the serial number of the effects you want to select, while the led digital tube still flashes, press the program knob to select the effect type of the led digital tube display number. When the program knob rotates counterclockwise, the digital tube display number decreases. When the program knob rotates clockwise, the digital tube display number increases.
PARAMETER control
For adjusting the parameter (depth, speed, etc.) for the selected effect. The last value used with each effect type is saved.
NOTE: When you change to a different effect type, the mixer automatically restores the value that was previously used with the newly selected effect (regardless of the current position of the PARAMETER).

• FX LEVEL: The FX LEVEL control feeds the FX signal into the main mix. If the control is turned all the way counterclockwise, no FX signal is present in the sum signal of the mixing console.
• AUX/USB/BT LEVEL: The AUX/USB/BT LEVEL control feeds the AUX/USB/BT signal into the main mix.  If the control is turned all the way counterclockwise, no AUX/USB/BT signal is present in the sum signal of the mixing console.
• PHONES/CTRL ROOM: The PHONES/CTRL ROOM control adjusts the level of both HEADPHONES and TRL ROOM outputs.
• MAIN LEVEL: The MAIN LEVEL control adjusts the level of all outputs.
• BREAK: The BREAK control mutes all outputs.
• USB/AUX TO CTRL ROOM: Press the USB/AUX switch if you want to monitor the USB/AUX input via the CTRL ROOM OUT. This provides an easy way to monitor the signals input from the USB/AUX input. Make sure they are correct and then adjust the AUX/USB/BT level knob to transmit the USB/AUX signal to the main output.
• FX TO CTRL ROOM: Press the FX switch if you want to monitor the FX signal via the CTRL ROOM OUT. This provides an easy way to monitor the signal input from the FX. Make sure they are correct and then adjust the FX level knob to transmit the FX signal to the main output.
• LEVEL INDICATOR: The high-precision 4-segment display accurately displays the relevant signal level.
  • Press to play/pause playback.
  • Press to go to the previous track. Press and hold to turn the volume down.
  • Press to go to the next track. Press and hold to turn the volume up.
  • MODE Press to select playback of USB or Bluetooth. When BLUE is displayed in the screen, turn on your phone Bluetooth and search for PRO TECH. Then connect to play the audio in your phone.
  • REC This mixer supports disk recording and computer recording.
  • USB: Press the REC button to start recording. Press again to pause the recording. Press and hold the REC button to save and play the recording file.
    • PC: After connecting to the computer, start the software “Adobe Audition” for recording. You can also try recording with other recording software.

Effect Programs
Here you can find a list of all presets stored in the multi-effects processor. This built-in effects module produces high-grade standard effects such as reverb, Chorus, flanger, delay, and various combination effects. Use the Aux Send FX on the channels and the Aux Send FX master control to determine the input signal of the effects processor. The built-in stereo effects processor has the advantage that it does not need to be wired up. This excludes the danger of humming or level mismatch right from the start and thus considerably facilitates use. These effect presets are classical “mixing effects”. If you move the STEREO AUX RETURN FX control, you mix the channel signal (dry) and the effect signal. You can control the balance between the two signals with the channel fader and the STEREO AUX RETURN FX control.
