| | LF +/-15dB @ 80Hz. |
| Insert Point: | Balanced send and return on TRS jacks. |
| Direct Output: | Balanced output on TRS jack. |
| | Nominal level +4dBu. |
| | Independent of EQ, mute switch and fader. |
| | Maximum level +26dBu. |
| Fader: | 100mm “K” Series, |
| | Mute and PFL switches and LED’s, |
| | Routing to L+R busses via Pan control, |
| | “Drive” LED with illumination increasing from +4dBu to +12dBu indicating valve signal level, |
| | “Peak” LED illuminating @ +19dBu, monitoring channel input amplifier and post fader signal. |
| L+R Outputs: | Balanced insertion points with +4dBu / -10dBu switch, |
| | Stereo Master fader, 100mm “K” Series, |
| | Output via balanced XLR connectors, |
| | Noise -76dBu (all channels Line Input @ 0dB gain) |
| | Maximum level +26dBu. |
| Aux Sends: | Aux 1 switchable “Pre” fader, |
| | Aux 2 post fader, |
| | Channel send level controls plus master level with PFL switch. |
| Stereo Return: | Balanced stereo returns, |
| | Left input normalled to Right input for mono compatibility, |
| | Aux 1 send level control, |
| | Level and balance controls and PFL switch with LED. |

| Monitoring: | Balanced outputs on TRS jacks, |
| | High quality level control with 29mm knob, |
| | PFL relative level trim control with +/-20dB range, |
| | Switch with LED to select one of two balanced 2 Track returns, |
| | LS mute switch with LED, |
| | Alt LS switch with LED, |
| | Headphone output with independent level control, |
| | Twin illuminated 45mm VU meters with “Peak” LED’s, |
| | Front panel accessable 0VU trims. |
| Power Supply: | External free standing supply, |
| | 2 metre cable attached to desk with plug and socket on PSU, |
| | PSU switchable for 110-220V 60Hz or 220-240V 50Hz use, |
| | Typical power consumption 100/140VA (8/12 channels). |
| | |
| Digital I/O: | Optional DO-2 ouput modules for L+R outputs, |
| | Optional DO-8 module for channels: outputs follow “Direct” |
| | outputs, inputs normalled to analogue “Line” inputs. |
