C2584 User Manual

 

 

1. GENERAL

The C2584 is dual mono (stereo) colour processor unit with 4 colour modules slots. Each independent channel has 2 colour slots connected in series. Each colour module can be engaged or disengaged by the designated bypass switch. Each channel has the INPUT LEVEL knob and OUTPUT LEVEL knob. The input stage of each channel has fixed gain of +12dB. INPUT LEVEL knob controls the signal level sent to the colour modules.

The INPUT LEVEL in not a GAIN knob, the gain of the input stage is fixed to +12dB. INPUT LEVEL knob sets the signal from NO SIGNAL (0) to maximum level of available signal. In the minimum position of the INPUT LEVEL knob the signal will be cut-off completely. To avoid over-driving the C2584 unit or the next stage, such as the interface, reduce the output level from the DAW by -12dB. If required, the input signal level from the DAW can be increased to achieve the desired saturation of the colour modules.

The output stage provides additional +6dB of fixed gain. The OUTPUT LEVEL knob controls the overall output signal level from the C2584 unit. The OUTPUT LEVEL knob sets the signal from NO SIGNAL (0) to maximum level of available signal. In the minimum position of the INPUT LEVEL knob the signal will be cut-off completely.

NOTE: The diagram above shows only 1 channel. The signal flow is identical for channel 1 and channel 2.

2. SIGNAL ROUTING (Each Channel).

Colour modules are connected in series. No parallel signal routing is possible. Signal will be first effected by the first colour module – L1 or R1 and passed to the next colour module inserted in the colour slot L2 or R2.

The increase of the input signal level controlled by the INPUT SIGNAL knob will have the biggest impact on the first colour module. Therefore it is recommended to insert the drive dependent colour modules ( Discrete Saturation, British Console) in first slot – L1 or R1.

The drive depended colour modules can also clip the signal, limiting the signal level passed to next colour module. Signal conditioning colours (DOPA520, Classic VCA) should be install in the second colour slot – L2 or R2.

Signal from the second colour slot is passed to OUTPUT LEVEL knob and next to the C2584 output.

Inputs of the C2584 are provided by the balanced TRS sockest on the front panel. Outputs of the C2584 are provided by the standard 500 rack XLR connectors located on the rear panel. The XLR adapter is included with the C2584.

3. TYPICAL USE OF C2584

The C2584 can be used for mastering the stereo track or to record the signal from the instrument such as keyboard. The total gain from input to output is +18dB, with bypassed colour modules and with all knobs set to maximum.

Before the use of C2584 put all knobs to 12 o’clock position. Reduce the output level of the DAW by -6dB. Make sure that all switches are in the LOW position (colour modules bypassed). Play the signal from DAW. Confirm that the signal returns back to the DAW system.

Engage selected colour modules, using the INPUT LEVEL knob adjust the level of saturation for colour modules. While increasing the input level with INPUT LEVEL knob control the DAW signal meter and reduce the signal with OUTPUT LEVEL knob to avoid clipping of the interface input stage.

Some colour modules can reduce the overall output signal level. Some clipping colour modules, such as Discrete Saturation, may act like primitive limiter. Further increase of the input signal will not increase the overall output signal level.

Above procedure can be used for mastering and recording.
