Input Gain/Trim Control. This knob provides the following gain structure for each channel:
Microphone Input XLR: 45dB of variable gain (+14 dB to +55dB)
Instrument HiZ Input TS ¼” (channels 1 and 2 only): 45 dB variable gain (+8dB to +50dB)
Line Input ¼” TRS/TS Channels 3 thru 8: -10dB to +10dB trim adjustment
Clip Indicator. The clip indicator will light up if your input signal from the XLR (Mic) or ¼” (line) reaches
+18dBu (0dBfs). At this level, your mic preamp/line trim signal may not exhibit signs of clipping such as
distortion. However, this level would cause the A/D (analog to digital) converters to clip. Therefore it is
highly recommended that you do not allow your converters to clip (the clip indicators to light up) as the
sound quality would not be desirable.
MAIN, MIX, PHONES, SYNC/POWER
Main. This knob allows control over the output level for the MAIN CR OUTPUT 1 and 2 on the back of the
FIREPOD. It has a range of -80db to +10dB.
Mix. The mix knob is like a balance control. It balances the headphone MAIN and CUE outputs between
Inputs 1-8 and playback outputs 1 and 2. This feature is an analog hardware mixer, so it allows you to
monitor the signal before it goes to your computer providing zero latency monitoring.
Phones. The Phones knob controls the amount of volume going to the headphone output on the front of
the unit. Notice the volume indicator goes to 11 (loud). Use this setting with caution.
Headphone Symbol and ¼” Jack. This is where you connect your headphones.
Red-Blue Power/Sync Light. This light is a clock (sync) indicator. It lets you know if your unit is receiving
word clock correctly. Word clock is the manner by which digital devices sync frame rates. Proper word
clock sync prevents digital devices from having pops, clicks, or distortion in the audio signal (due to
mismatched digital audio transmission).
Blue – solid sync
Red – sync not present.
Flashing Red and Blue – external sync not present
