Mackie SNOWBOX - 1;8 Stereo Line Input (Aux) Jack; 1;4 External FX Send;Return Jacks

SHOWBOX BATTERY POWERED ALL-IN-ONE PERFORMANCE RIG WITH BREAKAWAY MIX CONTROL

1/8" Stereo Line Input (Aux) Jack
This stereo line input is designed for /8" TRS balanced connections, such as a phone or tablet.
The volume of the /8" signal may be raised/lowered via the Channel 5-6 volume knob.
While it may look like Channels 5-6 includes the stereo /4" input jacks, the /8" aux input, and the Bluetooth
connection, all three may be used simultaneously!
This input will not have access to the internal FX engine, FX loop, or compressor – and these parameters
will not illuminate on the breakaway mixer. However, it will still have its own 3-band EQ.
NEVER connect the output of an amplifier directly to a ShowBox’s input jack.
This could damage the input circuitry and we wouldn’t want that now, would we?
1/4" External FX Send/Return Jacks
That’s correct, the ShowBox does come fully-equipped with eects, but if you have a guitar pedal
(or fify), they may be placed in front of the input jack or... connected via the FX loop!
In a nutshell, if the external FX send/return jacks are NOT used, an overdriven preamp on ShowBox
will distort and compress the pedals, essentially reducing the tone to hot garbage. However, plugging
a pedal board to these jacks bypasses the input – working (sort of) like an “insert” jack – afer
the ShowBox’s overdriven preamp, but before the high-headroom power section.
The input jack at the beginning of the pedal chain connects to the SEND jack and the output jack
at the end of the pedal chain connects to the RETURN jack. This allows the amp (ShowBox) and pedals to both retain their tonal
characteristics. The external FX loop knob – see page 26 – lowers and raises the volume of the externally connected eects.
Crank the ShowBox up without fear of ruining the glorious sounds of the attached guitar pedals.
Not all pedals have to be connected via the FX send and return jacks, nor do all pedals have to be connected
directly to the channel input.
Every musician has diering thoughts on what pedals go where and in what order, so listen to who you feel gives
you the best information... or more importantly, just listen to your ears, and mix and match to your heart’s content.
The send output jack sends a post-preamp (but pre-channel fader/DSP) signal for each channel.
The external FX loop knob on each channel applies the amount of signal sent though the send output jack.
The return input jack then sends the signal back into the external FX mix bus.
