Input Select, Line or Microphone: These 2 buttons set the gain to match the type of input device. They are mutually exclusive,
i.e. turning one on turns the other off. Microphone has 46dB more gain than Line.
Phantom Power: This button turns on or off 48 volt phantom power. This can only be turned on if Microphone is selected because
phantom power may damage line level equipment. Please consult the specifications of your microphone to see if phantom power is
required.
Monitor Channel: These buttons select whether or not that particular input channel is part of the mix for the selected monitor
channel. In the screen shot shown above, Monitor 1 is a mix of Inputs 1-6 and 8. Monitor 2 is a mix of Inputs 1-7.
Input Level: There is one slider control for each Input channel to control the recording level. Under each slider is the setting in dB.
To adjust a slider, move the mouse pointer over the slider knob and click and hold the left mouse button down and drag the slider
knob up or down. Or, you can move the mouse pointer over the slider knob and click the left mouse button once to set the “focus” on
the slider. Then, either use the up and down arrows on the keyboard or the scroll wheel on the mouse to adjust the slider. This
second method gives you finer control.
Sample Rate: This box shows the current sample rate setting. You cannot change the sample rate. This is set by your recording
software. If the sample rate is not what you expect, try opening your recording software and turning on the record monitor to see if
the sample rate changes.
Input LED: These indicator boxes have 4 colors; gray (off), green, yellow, and red. Green indicates audio activity; i.e. someone is
speaking into the microphone. If the indicator turns yellow, this means the threshold for the compressor/limiter has been reached. It
is OK for the indicator to be yellow occasionally. If the indicator turns red, this means the front end of the preamp is clipping. This
should not happen and cannot be corrected by moving the Input Level slider. If this happens, make sure you do not have the
Microphone setting on when you have Line Level equipment connected. If using Line Level equipment, see if there is an adjustment to
lower the output level. If the indicator turns red when using a microphone, the output of the microphone is too hot. Try moving the
microphone further away from the person speaking or installing a pad between the microphone and the DMX-88.
Monitor Level: These sliders adjust the output level of the Monitor outputs. Under each slider is the setting in dB. To adjust a
slider, move the mouse pointer over the slider knob and click and hold the left mouse button down and drag the slider knob up or
down. Or, you can move the mouse pointer over the slider knob and click the left mouse button once to set the “focus” on the slider.
Then, either use the up and down arrows on the keyboard or the scroll wheel on the mouse to adjust the slider. This second method
gives you finer control. Use care not to turn the level up too loud when the monitor output is connected to a teleconferencing system,
This may damage telephone equipment and/or be painfully loud to the person on the other end of the phone line.
