Mackie THUMP210XT - 1;8 Input Jack [Ch. 2]; MIC; Line Switch [Ch. 1]

THUMP210XT 10" 1400W ENHANCED COMPACT POWERED LOUDSPEAKER

In addition to accepting a balanced mic signal using an XLR connector, these input channels may also accept /4" line-level
signals driven by balanced or unbalanced sources.
To connect balanced lines to these inputs, use a /4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve, the three
connection points available on a stereo /4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals
and are wired as follows:
/4" TRS Balanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)
To connect unbalanced lines to these inputs, use a /4" mono (TS) phone plug, wired as follows:
/4" TS Unbalanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
NEVER connect the output of an amplifier directly to a Thump20XT’s input jack.
This could damage the input circuitry and we wouldn’t want that now, would we?
/8" Input Jack [Ch. 2]
This input channel may accept an /8" line-level signal from a phone, tablet, MP3 player, or other signal source.
NEVER connect the output of an amplifier directly to a Thump210XT’s input jack.
This could damage the input circuitry and we wouldn’t want that now, would we?
The /8" line-level connection may be used simultaneously with channel 2’s combo jack – XLR or /4" – and/or
Bluetooth connection. In other words, if there is a physical connection to the /8" line input, another physical
connection to the combo jack AND a device is connected via Bluetooth, none of those inputs will be interrupted.
An easy way to look at it is... there are extra inputs! The /8" line-level connection and XLR (or /4") connection
sum together and do not override each other.
Mic / Line Switch [Ch. ]
Because an XLR connector may be connected to a mic or an instrument, this switch adjusts the channel’s
input sensitivity to optimize channel  for mic or line-level signals. If a mic is connected, this switch should
be engaged and the gain knob set to mic. If an instrument is connected to channel  (via XLR), this switch
should be disengaged and the gain knob set to line.
