Please refer to the diagrams and features described in this manual that describe the features and functions of the Commander 2. 13 8 9 5 6 7 10 4 1: INPUT JACKS A and B – Connect 2 instruments here. Connections are for unbalanced tip/sleeve instrument type plugs. 2: INPUT TRIM CONTROLS and LED INDICATORS – These two trim controls are used to adjust the input level and to balance the level between the two instruments connected to the A and B input jacks. 1 2 3 11 12 Turn up the TRIM control until the loudest peaks from each instrument cause the control shaft LED to flash briefly. Both channels may be set without switching between A and B with the footswitch. After setting both LEDs, you may want to fine-tune the input level on one or both inputs to equalize the volume between the two instruments. When doing this adjustment, be sure that the BOOST function is turned off. 3: OUTPUT JACK – is an unbalanced ¼” tip/sleeve jack for making connections to an amplifier, powered speaker, mixer, etc. 4: POL REV BUTTON – reverses the polarity of both the ¼” unbalanced output and the XLR DI output. This can be especially useful for reducing feedback from interaction with a nearby monitor speaker. Changing the setting of this button may also result in a cleaner sound when your instrument is mixed with other band instruments in the sound system. Experiment to find the setting that works best for your individual application. 5: DI OUT – Provides a high quality, transformer isolated, balanced, low-impedance microphone level signal for connecting to a mic input in a professional mixing console. This is typically the output that would be used when running longer distances down a snake to a mix position. 6: DI GND LIFT BUTTON – Disconnects the ground connection between the ¼” output jack and pin-1 of the XLR DI output. This can be useful for reducing or eliminating ground loop hum and buzz that can sometimes occur when two pieces of electronic gear are connected together. For example, if the Commander 2’s ¼” out is connected to a stage monitor amplifier and the XLR DI out is connected to the sound system mixer, ground interaction between the amp and the mixer might cause ground loop noise. This button is normally kept in the “GND” position (OUT) but if hum or buzz is encountered, try placing the button in the “LIFT” position (IN). 7: A/B FOOTSWITCH and INDICATOR LEDs – The footswitch toggles the OUTPUT between the A and B INPUTS. Only one input can be activated at a time. A corresponding LED will light to indicate which channel is active, A on the left, B on the right. 8: LOOP SEND and RETURN JACKS – Provide a connection for external effects such as an outboard EQ or effects unit. Use the SEND jack to provide the signal to the outboard equipment. Use the RETURN jack to “return” the signal back into the Commander 2 where it continues on to the outputs. The RETURN jack opens an internal connection in the COMMANDER 2 so that the signal going through the Commander 2 is diverted through the loop. The SEND jack by itself does not break the internal connection through the Commander 2 and therefore can be used as an extra output when the RETURN jack is left unused. 9: NOTCH FILTER BUTTON and FREQ CONTROL – Use this feature to kill the howling feedback that can often occur because of interaction between monitor speakers and acoustic instruments, especially the lower strings on an acoustic guitar. If you experience feedback, engage the NOTCH button and rotate the FREQ control throughout its range of 55 – 320 Hz. When you encounter the offending frequency, the feedback will be notched out and disappear. Note: The feedback elimination is accomplished by applying a deep notch filter to your instruments signal to reduce a narrow band of frequencies that are causing feedback. The notch is very narrow so that you will notice little or no change in the tone of your instrument. However, if the monitor speakers are extremely loud or if you raise the volume of your instrument or monitor, the notch may not be able to provide enough reduction to eliminate the feedback or a second frequency may also feed back. If this occurs, reduce the volume level of instrument and/or monitor. 10: BATTERY - To replace the battery, turn the front thumbscrews counterclockwise about four full turns exposing about 1/4” of their threads. Slide the top of the unit toward the thumbscrews as far as it will go and then rotate it upward to expose the battery. To close the unit, reverse the process. 11: A and B BOOST CONTROLS, BOOST FOOTSWITCH and BOOST LED INDICATOR – Sets the amount of boost that will be independently applied to each channel, A or B, when the BOOST function is activated. Press and release the BOOST footswitch to toggle the BOOST preset function on and off. The BOOST indicator LED will illuminate when the BOOST is activated. 12: TUNER FOOTSWITCH and DISPLAY WINDOW – The tuner in the Commander 2 is simple, precise, stable, fast and easy to use with an extra bright display for tuning under bright lights or outdoors. Press the TUNER footswitch to activate the tuner for the selected channel, A or B. When activated, all outputs are muted for silent tuning. Pluck a string and the display window will indicate the note that is being played. A pair of dots in the upper corners of the display indicates the sharp (#) of the note. Example, a “C” plus the dots indicates that a C# note is detected. Tune your string up or down until the proper note is displayed. Once the correct note is displayed, the row of colored LEDs above the display indicates whether that note is sharp or flat. LEDs lit to the left of center indicate a note that is flat, tune up. LEDs lit to the right of center indicate a note that is sharp, tune down. When the the note is in tune, both outside yellow LEDs plus the center blue LED will light, After tuning, press the TUNE footswitch again to turn the tuner off and turn the Commander 2’s outputs back on. When using the Commander 2 on battery power, it is not recommended that you leave the tuner activated when not actually tuning as the tuner mode draws a higher amount of current from the battery and can shorten battery life. 13: 9-VOLT POWER INLET –Connect a standard 3.5 mm 9 Volt DC regulated supply, 100 mA capacity or greater with a center negative plug. The Whirlwind PS9V-EFX is recommended for proper operation. + -
