4.1 The MONO MIC/LINE CHANNELS

These are Channel 1 and Channel 2. You can connect a balanced, low impedance microphone to the XLR socket. ON the 1/4" phone jack you can

connect either a microphone or a line level instrument. You shall never connect an unbalanced microphone to the XLR socket if you do not want to damage both the Microphone and the Mixer.

18 Volt Phantom power

It is available only to the XLR input sockets. Do not connect nonphantom equipment to the MIC input when phantom power is on. Before turning phantom power on, make sure that all faders are all the way down. In this way you will protect your stage monitors and main loudspeakers.

4.4 3-BAND EQUALIZER

3-band equaliser is provided for all input channels with a wide range of frequency adjustment.

-HI

This is the treble control. You can use it to get rid of high frequency noises or to boost the sound of cymbals or the high harmonics of the human voice. The gain range goes from -15dB to +15dB with a center frequency of 12kHz.

- MID

This is the midrange control. It can affect most fundamental frequencies of all musical instruments and human voice. An attentive use of this control will give you a very wide panorama of sound effects. The gain range goes from -12dB to +12dB and the center frequency is 2.5kHz.

- LOW

This is the bass control. Boost male voice or kickdrum and bass guitar. Your system will sound much bigger than what it is. The gain range goes from -15dB to +15dB and the center frequency is 80Hz.

4.5 AUX

This control is used to adjust the level of respective channel signal sent to the Auxiliary Bus. The configuration is post-fader so the signal sent to the AUX Bus will be affected by the LEVEL control of that particular channel. In this typical compact unit, the channel signal is not only assigned to external effect or processor equipment directly but also to internal onboard effect module.

4.6 PAN

This is the PANORAMA control, or balance control. You can adjust the stereo image of the signal via this control. Keep this control in center position and your signal will be positioned in the middle of stage. Turn this control fully counterclockwise and the signal will be present only on the left speaker and vice-versa. Of course a large number of intermediate positions is available.

4.7 PEAK LED

Inside your mixer the audio signal is monitored in several different stages and then sent to the PEAK LED. When this LED blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK LED will blink with a level that is 6dB before actual clipping.

The fan can accelerate the flow of air to lower the temperature inside power supply. The inside temperature determines the fan speed which controls the inside air flowing speed.

5. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your PM-6 DRAGONFLY. However, we advise you to read carefully the following section to be the real master of your own Mixer. Not paying enough attention to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow these procedures for every single channel:

1). Before connecting mics or instruments, make sure that the power of all your systems components including the mixer is turned off. Also, make sure that all input and output controls are turned down. This will avoid damage to your speakers and excessive noise.

2). Properly connect all external equipments such as microphone, power amplifier, speakers etc.

3). Now, turn on the power of any peripheral devices, then connect the 24V DC power supply box to the mixer and main power.

Note: the power amplifier or powered monitors shall be turned on after the mixer and off before the mixer.turned

4). Set the output level of your mixer or the connected power amplifier at no more than 75%.

5). Set the CONTROL ROOM/PHONE level at no more than 50%.

6). Position HI, MID and LOW EQ controls on middle postion.

7). Position panoramic (PAN/BAL) control on center position.

8). While speaking into the mic(or playing the instrument), adjust the channel Level control so that the PEAK LED

will blink occasionally, in this way you will maintain good headroom and ideal dynamic range.

9). You can shape the tone of each channel by adjusting the equalizer controls as desired.

10). Now repeat the same sequence for all input channels. The Main LED Meter could move up into the red section. in this case you can adjust the overall output level through the MAIN MIX control.

6. FOR THE EXPERTS WHO WANTS TO KNOW MORE

As we have told you previously in this manual, the Aux Send Control both on mono and stereo channels is factory wired as POST-FADER. If you are skilled in electronic components soldering you can modify this setting and have all your AUX sends configured as PRE-FADER.
