286s
Operating Controls | Section 2 |
To use the INSERT jack to MULT the preamp out (i.e., to provide an output with a buffered version of the signal after the Mic Preamp circuitry, but before the Processing Section), insert a Mono 1/4” plug fully into the INSERT jack, then pull the plug out one click. Plug the other end of the cable to the appropriate load. This will still allow the original signal path to continue to the Processing Section without interruption.
Note: If the plug is accidentally pushed fully into the INSERT jack, it will break off the connection between the Mic Preamp and Processing Sections; in this case, there would be no signal at the 286s LINE OUTPUT jack.
AC PowerConnect the AC power cord to the AC receptacle on the back of the unit. Route the AC power cord to a convenient power outlet away from audio lines. The unit may be turned on and off from a master equipment power switch.

Note: To reduce the risk of damage to your system, set the MIC GAIN control fully counterclockwise and lower your playback monitor levels before you connect a microphone, power on the unit, or press the PHANTOM button. This will eliminate spikes and surges, acoustical feedback, loud pops, momentary hiss, or other unwanted sounds.

Note: To get the lowest noise possible from the 286s, set the input attenuators (if any) on your recorder or mixer for nominal levels (often about 3/4” of the way up or at the detent position; refer to the device’s operating manual). Then, set the 286s MIC GAIN so that your recorder or mixer is at its optimal operating level.
The red CLIP LED (located to the left of the MIC GAIN control) indicates that the combination
