CSX-18 Series Live Mixing Console
CSX-18 mixing console has been developed to provide
comprehensive range of audio requirements with high quality, reliable
results. Please read and keep this manual to achieve the best results
from your purchase and avoid damage through misuse.
Console Layout
The CSX-18 has comprehensive input and output sections which can be
split further into various stages of processing and routing. All preamps
have studio grade, low noise architecture for the cleanest possible path
throughout the signal chain.
The input stages are repeated across each channel of the console, which
simplifies operation and enables quick and easy location of various
controls. The following pages of this manual are divided up into these
stages to explain the details and function of each control.
Mic/Line Input Connections
Channel inputs are provided as XLR and/or 6.3mm jack sockets.
The connections for these inputs are assigned as follows.
Channel Functions
- MIC / Line input Connect a balanced microphone
or line input to this XLRF input.
An unbalanced microphone or line signal can be connected by XLR
provided that +48V phantom power is not used. Wired as follows.
| Balanced |
Pin 1 = Ground |
Pin 2 = Signal + |
Pin 3 = Signal – |
| Unbalanced |
Pin 1 = Ground |
Pin 2 = Signal + |
Pin 3 = Ground |
The Mic/Line input can also accept a 6.3mm balanced TRS or unbalanced
TS plug (jack plug). Phantom power does not affect
this connection. Wired as follows.
| Balanced |
Tip = Signal + |
Ring = Signal – |
Sleeve = Ground |
| Unbalanced |
Tip = Signal + |
Ring = Ground |
Sleeve = Ground |
2. Clip LED The CLIP LED lights when the channel is being overloaded.
Ideally, the Gain rotary control (described below) should be adjusted
so that the loudest passages of the input signal (e.g. bass drum
beats) will just momentarily trigger the CLIP LED. Anything longer
than a momentary flicker of the CLIP LED means that the Gain should be
reduced. Using the PFL button further down the channel strip gives a
more detailed view of the channel level on the main VU LEDs.
3. GAIN control This control trims the input signal to the optimum
level for the channel strip circuitry.
Too low a signal level can result in a weak signal-to-noise ratio and
too high can result in overload and distortion in the signal output.
4. Stereo inputs The two right-most input channels on the console are
stereo with
Left and Right 6.3mm jack inputs. Alternatively, a mono signal can be
connected to the Left input jack and the channel will effectively
operate as a mono channel.
EQ Section
5. HIGH This control can boost or cut the high frequencies (centre 12kHz) by ±15dB (12 o’clock position is zero)
6. MID This control can boost or cut the mid frequencies (centre
2.5kHz) by ±15dB (12 o’clock position is zero)
7. LOW This control can boost or cut the low frequencies (centre 80Hz) by ±15dB (12 o’clock position isero)
Channel Routing
8. AUX This control governs the amount of signal from the channel
routed to the AUX SEND or auxiliary output to external equipment.
9.POST / PRE Pressing this button in changes the AUX output from POST
to PRE. POST is post-fader, meaning the signals to the AUX output are also affected by the channel fader level. PRE is pre-fader, meaning the signals to the AUX output are not affected by the channel fader level.
10. FX This control governs the amount of signal from the channel routed
to the effects section
11. PAN/BAL This control adjusts the amount of signal from the channel
fed to Left or Right outputs.
This varies the point in the stereo field that the signal appears. For
ST1 and ST2 channels, the PAN control is replaced with a BAL control
for Left/Right balance.
Channel Faders
12. PFL Pre-Fade Listen sends the channel signal direct to monitoring. This means that the channel signal is shown on the main VU LEDs and routed directly to the headphones output. If many PFLs or AFLs are selected, all are routed to monitoring.
13. Channel fader 60mm fader to adjust the channel level to the master
output.
Output Section
14. 2-TRACK INPUT L+R RCA line input shared with MPR
15. 2-TRACK OUT L+R RCA line output for recording or Monitoring
(pre-master-fader)
MAIN L/R OUT L+R
16.MAIN L/R OUT L+R balanced XLR main outputs
17. AUX SEND 6.3mm jack mix of all channel AUX feeds
18. FX MUTE Connect a non-latching footswitch to this 6.3mm jack to mute/unmute the output of the DSP effects when pressed.
19. MONITOR OUT L+R 6.3mm jack outputs for monitoring. Volume is controlled by PHONES LEVEL.
20. PHONES Stereo 6.3mm jack headphones output. Volume is controlled by PHONES LEVEL.
Graphic Equalizer
The main EQ is a stereo 7-band graphic equalizer to give overall tone shaping and can be used to help avoid feedback in live microphone setups.
Each slider controls a boost or cut of up to 12dB centred at the
specified frequency. Running from bass to treble, these are 63Hz, 160Hz, 500Hz, 1kHz, 2.5kHz, 6.3kHz and 16kHz
