REAR PANEL
8. Foot Switch Jacks (Impact X only)
This port is for the inclusion of a foot switch (non-latchable),
used to remotely adjust properties of the Impact X’s built-in
Digital Effects Engine. Using a footswitch with this jack will
allow users to mute and un-mute the Digital Effects.
9. Control Room / Phones
These two 1/4” Phone Jack outputs feed the signal al-
tered by the Control Room level control on the face of the
mixer. This output has extensive use, as it can be used to
feed the signal from the mixer to an active monitor, for the
monitoring of the audio signal from within a booth, among
many other possible uses.
10. Mono / Subwoofer Output
This male XLR and 1/4” TS output feeds a monaural sig-
nal of the Main L-R signals combined, as adjusted by the
accompanying level control. This is ideal for use with a
mono sound system, or for the addition of a subwoofer to
your set of speakers, adding more punch to low frequency
sounds.
11. Main Outputs
These outputs will output the final stereo line level signal
sent from the main mixing bus. The primary purpose of the
two male XLR jacks and 1/4” phone jacks is to send the
main left and right output signal to external devices, which
may include power amplifiers (and in-turn, a pair of speak
-
ers), other mixers, as well as a wide range of other possible
signal processors (equalizers, crossovers, etcetera).
12. 12V Lamp
This XLR socket allows you to attach a 12 Volt (7 Watt)
gooseneck lamp, allowing better visability in areas with
poor light.
13. Power Connector
This is for the addition of an AC power
cable, allowing power to be supplied to
the mixer. Please use the power cable
that is included with this mixer only.
The Fuse holder, located below the
AC Power connector, is, of course, for
the Impact’s fuse. If the fuse happens
to blow, open the holder cover, and re-
place the fuse with a suitable replace-
ment (as indicated underneath the
power connector).

14. Tape Inputs
The first of these inputs accommodates RCA cables from
such devices as tape and CD players. In addition to these
inputs, however, Phonic has incorporated a mini stereo
port for the inclusion of mini disc (MD), portable CD, and
MP3 players (such as the Apple iPod), as well as laptop
computers. The line from this feed is directed to the Tape
In mixing bus, which users are able to feed to the Control
Room, AUX 1 and 2 or Main L/R mixing buses.
15. Record Outputs
As with the Tape In ports, these outputs will accommo-
date RCA cables, able to be fed to a variety of recording
devices. Also included are mini stereo ports for the addi-
tion of recording devices such as MD players and laptop
computers.
16. Headphones Output
This output port is best suited for use with headphones,
allowing monitoring of the mix. The audio level of this out-
put is controlled using the Control Room / Phones control
on the front panel’s master section.
