Did EVERFI modules 3 & 4 from IGNITION.  Your scores from these modules will count as a small test grade.

 

Started learning about a mixing board for ART/AV TECH/COMM test next week.  We are learning about the mixer we use here at FHS for the sound in the gym.  Here is a LINK to the ALESIS Multimix 10 Wireless User Guide. 

 

Also see picture BELOW.

 

Four of the channels are for wireless microphones.  These are connected in the back.  If you plug a hardwired microphone into INPUT 1 or INPUT 2 on the front panel then the hardwired mic overrides the wireless mic (wireless 1 or wireless 2).

 

TRIM is for adjusting the input level to keep the peak light just below activation.  Allowing the input to get above peak can cause speaker damage or failure.

 

HI controls the 12kHZ range which is the higher side of human hearing.  This is similar to the TREBLE knob on basic stereos.  It has a range of +/- 15dB.  15dB is about 3X louder or 3X softer.

 

LO controls the 80HZ range which is the lower side of human hearing.  This is similar to the BASS knob on stereos.  It has a range of +/- 15dB.  15dB is about 3X louder or 3X softer.

 

AUX1 PRE is for monitors.  Any of the 6 channels can be "mixed" to the AUX1 PRE output.  This output is before (PRE) the channel's fader.  If the fader is off, AUX1 PRE will still output.

 

AUX2 POST is for effects like reverb or echo.  Any of the 6 channels can be "mixed" to the AUX2 POST output.  This output is after (POST) the channel's fader and is therefore dependent on the channel's volume.

 

BAL is balance and determines left or right output.

 

CHANNEL FADER controls the volume for the channel.

 

20dB is 10 X as intense as 10dB and 2 X as loud.

30dB is 100 X as intense as 10dB and 4 X as loud.

40dB is 1000 X intense as 10dB and is 8 X as loud.
