1. Instrument Inputs 1 and 2 (Inst) –Thesefront-panelconnectorsprovideinstrument-levelinputsforchannels1and2.
Eachofthesetwoinputswillacceptahigh-impedanceinstrumentlevelsignalonanunbalanced1/4”plug.Setthe
Mic/Line - Instrument switch
2
tothe“in”positiontoactivatethecorrespondingfront-panelinput.
2. Mic/Line - Instrument Level Switches ( / ) – These switches select the input source for
channels1/2betweenthefront-panelInstrumentinputs
1
and the rear-panel Mic/Line inputs
20
.
3. LED Clip Meters (Clip) – These red LEDs illuminate when an input signal reaches a sustained clipping level. Reduce
the channel’s Input Gain level
5
if the LED glows steadily red.
4. LED Level Meters – These green LEDs illuminate when an input signal of -40 dBFS is present at the corresponding input.
5. Mic/Instrument Gain/Pad 1-8 (Mic/Inst Gain Pull -20dB) – These knobs adjust the input gain level for channels
1through8.Pullingtheknoboutwillengagea20dBpadontheMicandInstrumentinput.Pushingtheknobinwill
disengagethepad.(NotethatthelevelcontrolsonlyaffecttheXLRmicandfrontpanelinstrumentinputs,butdonot
affecttheline-levelinputs.)
6. Phantom Power Switches (Phantom Power) – Pressing these switches activates the phantom power circuitry for the
correspondinggroupoffourmicinputs(1through4or5through8),illuminatingthePhantomPowerLED
7
and sending
48VpowertothefourassociatedXLRinputs
20
, for use with condenser microphones requiring external power.
7. Phantom Power LED – These red LEDs light to indicate that the corresponding phantom power switch
6
has been
pressed,applying+48Vphantompowertotheselectedgroupoffourmicinputs.
8. Headphone Output Levels (
1
/
2 )
– These two knobs control the volume level for the two headphone outputs
9
.
9. Headphone Outputs (
1
/
2 )
–Thesetwo1/4”stereo(TRS)jacksareindependentofthemainaudiooutputlevel,
and are controlled by the headphone output knobs
8
. The first headphone jack outputs the same audio signal as
rear-paneloutputs1/2whilethesecondheadphonejackoutputsthesameaudiosignalasrear-paneloutputs3/4.
10. Main Output Level (Output) –Thisknobcontrolsthemainoutputlevel(outputpair1/2).
11. MIDI Input LED (MIDI In) –This green LED lights when MIDI data is present at the MIDI input
18
.
12. MIDI Output LED (MIDI Out) – This green LED lights when MIDI data is present at the MIDI output
18
.
13. Power Switch (
) – Pressing this button will power on Fast Track Ultra 8R, illuminating the front-panel Power LED
14
.
The unit must be connected to the external power supply.
14. Power LED (Power) – This blue LED lights when the power switch
13
has been pressed and power is being received
from the external power supply.
