| from the main outputs and can therefore provide addi- |
| tional outputs for foldback or external processing units. |
| The six Auxiliary busses are arranged in two sections |
| of three, with each section comprising a |
| back (FB) send and two |
| auxiliary sends. Normally FB1 and AUX 1 & 2 are in |
| the Channel path, while FB2 and AUX 3 & 4 are in the |
| Monitor path. |

13. | CHANNEL PAN |
| The Pan control determines the position of the Channel |
| signal within the stereo image. Rotation fully anticlock- |
| wise feeds the signal solely to the Left mix buss and |
| |
| sweeps the image to the Right and |
| Groups. |

14. | CHANNEL PFL/PEAK LED |
| When the PFL switch is pressed, the |
| fed to the Control Room and headphones outputs, |
| where it replaces the selected source. The PFL/AFL |
| LED on the master section illuminates to warn that the |
| monitor and the meters are now responding to the |
| PFL/AFL selection and the PFL LED on the input chan- |
| nel lights to identify the active channel. This is a useful |
| way of listening to any required input signal without in- |
| terrupting the main mix, so that adjustments can be |
| made or problems traced. |
| When the PFL switch is released the LED on the chan- |
| nel serves as a PEAK indicator, to warn when an |
| excessively high signal level is present in the channel. |
| The signal is sampled at two points in the channel, |
| PRE INSERT, (PRE HF/LF EQ if in the Channel path), |
| and POST EQ. The Peak LED will illuminate approxi- |
| mately 4dB before clipping and therefore give warning |
| of a possible overload even if the peaks are removed |
| by external equipment plugged into the Insert. |

15. | CHANNEL ON |
| This switch routes the Channel signal to the Channel |
PAN control and then to the routing matrix. It is posi- tioned
