Console layout

Each CSP/CSL mixing console 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 Section

Channel inputs and inserts are provided as XLR and/or 6.3mm jack sockets. The connections for these inputs are assigned as follows.

1. MIC input
   Balanced Unbalanced

   Balanced	Pin 1 = Ground	Pin 2 = Signal +	Pin 3 = Signal —
   Unbalanced	Pin 1 = Ground	Pin 2 = Signal +	Pin 3 = Ground

2. LINE input
   Balanced Unbalanced

   Balanced	Tip = Signal +	Ring = Signal —	Sleeve = Ground
   Unbalanced	Tip = Signal +	–	Sleeve = Ground

3. L/MONO input
4. RIGHT input
   

   Balanced	Tip = Signal +	Ring = Signal —	Sleeve = Ground
   Unbalanced	Tip = Signal +	–	Sleeve = Ground

5. 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.
   The PEAK LED next to the channel fader will give an indication of the signal level. Ideally, the Gain rotary control should be adjusted so that the loudest passages of the
   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.
   EQ Section
6. HIGH
   
   This control can boost or cut the high frequencies (center 12kHz) by ±15dB (12 o’clock position is zero)
7. MID
   This control can boost or cut the mid frequencies (center 2.5kHz) by ±15dB (12 o’clock position is zero)
8.  LOW
   This control can boost or cut the low frequencies (center 80Hz) by ±15dB (12 o’clock position is zero)Channel Routing
   

9. AUX
   This control governs the amount of signal from the channel routed to the AUX SEND or auxiliary output to external equipment. (This control is post-fader – i.e. the signal routed to AUX SEND is also affected by the channel fader level)

10. . FX
    This control governs the amount of signal from the channel routed to the DSP effects engine. If a jack is connected to the FX SEND connector (see 37 below), this will operate as an extra AUX output (This control is post-fader – i.e. the signal routed to AUX SEND is also affected by the channel fader level)

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 the Left/Right balance.

    Channel Faders
    

12.  PEAK LED
    An indicator showing when the signal reaches the maximum level and clipping.

13.  PDF
    Pre-Fader Listen sends the channel signal direct to monitoring. This means that the channel signal is shown on the main VU LEDs. Also, the signal is routed directly to the headphone’s output. This allows the particular channel signal to be checked. If many PFLs or AFLs are selected, all are routed to monitoring.

14. Channel fader 60mm fader to adjust the channel level to the master output. A dB scale is provided to show the level of boost or cut.Graphic Equalizer
    The main EQ is a stereo 7-band graphic equalizer, offering refined audio spectrum sharing and feedback control for live mic situations.
15. EQ sliders.
    Each slider controls a boost or cuts of up to 12dB centered at the specified frequency.DSP Effects Engine
    CSP and CSL series mixers each have an internal 24-bit DSP processor for audio effects, as detailed on the DSP Table (on the following page)
16.  6-segment LED
    Indicates overall input level to DSP
17. Program display
    Indicates selected program (see table on next page)
18. TAP
    Press once to switch the rotary control (27) to PARAMETER 2.

    Tap the TAP button rhythmically more than twice to set a tempo for time effects An LED to the left of the Tap switch flashes to indicate time intervals

19. PROGRAM/PARAMETER
    Turn this rotary encoder to select a program.
    The numerical display will flash the selected program number.
    Press the encoder to confirm the selection, the display will stop flashing & the selected program will be active.

    Press the encoder again and a dot will appear in the display indicating PARAMETER 1. Turning the encoder will change PARAMETER 1 for the selected program as detailed in the DSP Table on the following page.

    Pressing the TAP button (26) will switch to PARAMETER 2 and then turning the encoder will change PARAMETER 2 for the selected program.

    These parameter changes are stored for when the program is selected in the future.

39.  Power switch
    Illuminated rocker switch for main power on/off.
40.  Fuse holder
    Integral holder for 5 x 20mm fuse. Replace only with the type indicated.
41.  IEC mains inlet
    Mains connection. Ensure voltage as indicated. Use IEC lead supplied.

Powering up
Connect the IEC inlet (40) to mains power using the supplied mains lead. In case of the fuse blowing, replace only with the type indicated. If the fuse is repeatedly blowing, refer to qualified service personnel.
The illuminated rocker switch activates the main power to the unit.

Phantom power
In addition to the mains power switch, the rear panel has an additional rocker switch which when switched on, enables +48V phantom power to the XLR input connectors. This is mainly used for condenser microphones that do not have an internal battery or to remotely power D.I. boxes for patching instruments directly into the mixer.
Connecting Speakers (CSP only)
When connecting speakers to the CSP-series mixers, ensure that the combined load for each output (left or right) is no lower than 4 Ohms (4Ω). To make sure of this, check the speaker manufacturer’s information.

If connecting more than one speaker to an output channel, observe the following calculation method.

Note: normally, speakers will be connected in parallel by connecting a speaker lead from one to another.
Most PA and sound reinforcement speakers are 8Ω, so we consider that 1/8 + 1/8 = 1/4.
Therefore, when connecting 2 x 8Ω speakers together in parallel, the resulting total load is 4Ω.

It is also important to ensure that the power delivered to the speakers will not overload them.

When connecting 2 x 8Ω speakers together on one channel, each speaker will equally receive half of the output of that channel.
