Re: Thunder FX from Laptop
I have a cd player that plays from 3.5 to 1/4" and plays fine. Does that mean the CD is
mono? The
mixer has 2
line inputs on one
channel and one is labeled for
mono.
I assume this is the same
Mackie PPM 808M from the other thread, of so then as far as I can tell Inputs 1 through 6 have a balanced 1/4"
mono line input while Inputs 7 and 8 have unbalanced 1/4" stereo
line inputs (although according to the single
line diagram they are actually
TRS 1/4" jacks) that are immediately summed to
mono. It's a
mono mixer so there is no panning.
It sounds like you are using the stereo inputs on Input 7 or 8. What cable do you have between the laptop and the
mixer an how is it wired? If it is a 3.5mm
TRS stereo mini to two TS 1/4" jacks and are plugged into both the left and right inputs on a
channel then you should get both audio channels from the laptop, however they will be summed to
mono. If the cable is a 3.5mm
TRS mini to a single
TRS 1/4" and you are going into one
channel of the stereo inputs input then you would get just that one
channel from the laptop.
Another consideration, you actually have two
level controls for each
channel. There is a larger "Volume" knob that is comparable to the
fader on other mixers and would be how you would adjust the
level during use, but above that is a smaller "Input
Level Set"
level control that is equivalent to a
gain/
trim control on a
console. Turn down the Volume control and adjust the "Input
Level Set" knob until the
LED just starts to blink on the highest peak levels, then use the "Volume" knob to adjust the mix
level. With the headphone output from the laptop you may have to turn down the "Input
Level Set" control quite a
bit to account for the greater
level of the laptop headphone output.
