| Dimensions: | All consoles are 815mm (32”) deep, plus at least 100mm (4”) |
| at rear of console for PSU and audio connections, |
| All consoles are 222mm (8.75”) high. |
| Length of 16 channel console 694mm (27.3”), |
| Length of 24 channel console 950mm (37.4”), |
| Length of 32 channel console 1206mm (47.5”). |

| Note: | Distortion measured Line Input to Track Output at +4dBu input and 0dB |
| gain over a bandwidth of 20Hz to 20KHz. The distortion is predominately |
| | tube generated second harmonic. Increasing the “Drive “ level by applying |
| | more input gain progressively increases the distortion. |
| The above figures are representitive of typical production consoles, but are not guaranteed limits for any particular console. These specifications are subject to change without notice. |
