AUX INPUT: This amplifier includes a 1/4" (6.35mm) TRS AUX input. This TRS stereo jack sums left and right channels

from an MP-3 player, i-device, tablet. For upright players, this input can be used to plug the output of your upright's outboard

preamp into the power amplifier. The input level is set by the MASTER VOLUME control, as well as the volume control on

the external device. This signal will not be present in the DI output. On the TT-800 only, the signal insert point is after the

channel master volume controls, so the playback device's volume control must be used.

HEADPHONE OUTPUT: This 1/4" (6.35mm) TRS tip-ring-sleeve headphone output jack, will drive all common headphones

and IEM ear pieces. It is not necessary to have a speaker connected to the amp when using headphones, it is

completely safe to operate the amp without a speaker load. It's advisable to use caution whenever sticking a sound

source in your ear, as damaging volume is possible. This output should not be connected to anything but headphones,

ear buds or IEM ear pieces.

DIRECT OUTPUTS (DI OUT): This output is capable of driving balanced analog lines as long as 500 feet, is fully phantom

power protected, noise resistant and stability compensated for a reliable, low noise floor, high quality signal output to mixing

consoles and recording interfaces.

DIRECT OUTPUT SOURCE SWITCH: This switch selects the signal source routing that is used to derive the direct output

signal. In the PRE position, the signal is sourced directly from the input buffer. Muting the amplifier by the front panel mute

switch mutes this output to allow for silent tuning. In the POST position, the signal is sourced from the output of the equalizer

section and before the master volume control.

DIRECT OUTPUT LEVEL SWITCH: This switch configures the level of the direct output to either mic level or line level.

DIRECT OUTPUT PIN 1 LIFT SWITCH: This switch connects or lifts the circuit ground/earth/common connection from pin

1 on the XLR DI OUT connector to reduce noise on the DI output signal due to ground/earth loops. The general idea is to

choose the position with minimum noise.

FOOT SWITCH JACKS: When present, these are for the connection of latching foot switches which are available from your

Mesa/Boogie dealer.

USB POWER PORT: Provides power (not data) to USB devices that might be used in conjunction with practicing, recording,

jamming or even performing. It may also be used to recharge phones, MP-3 players, iPods, and other devices. Rated current

is 500mA maximum, and it conforms to the Apple USB charge current standard. This USB power port can also be used to

drive any number of USB devices, including power converters that provide 9 volt pedal power. Because pedal power devices

step up the voltage, the available current becomes ~300 mA at 9V.
