[. . . ] It is a 2-pole (12dB per octave) filter with a corner frequency set at 100Hz. The filter affects signals from both Mic XLR and Line jack socket. 0. 00 -10. 00 -20. 00 -30. 00 -40. 00 -50. 00 10. 00 Hz 100. 00 1000. 00 10000. 00 30000. 00 Allen & Heath 14 ZED-14, 18 & 24 User Guide MONO INPUT CHANNEL 0 20 10 GAIN 10 30 40 50 63 26 HF EQ The HF (High Frequency) equaliser affects the frequency response of the higher audible frequencies. The corner frequency of 12kHz is around 3dB from the maximum cut or boost of the circuit. It has plenty of gain and actually gives slightly more that the +/-15dB legend suggests. 0 MIC LINE -10 -6 dBr 20. 00 100Hz 15. 00 10. 00 5. 00 12kHz HF 0. 00 -5. 00 -10. 00 -15. 00 -15 500 200 650 +15 1k 2k 3k 4k -20. 00 10. 00 Hz 100. 00 1000. 00 10000. 00 30000. 00 MF EQ The MF (Mid Frequency) equaliser affects the middle of the audible frequency range. The frequency graduations on the sweep control are the centre frequencies of the EQ. The range has been carefully chosen to cover “boomy” frequencies around 120Hz to 250Hz which may need cutting back, or a lift at 2 to 3kHz may be required for microphone intelligibility. 120Hz HM dBr 20. 00 -15 +15 15. 00 10. 00 80Hz LF 5. 00 0. 00 -5. 00 -10. 00 -15 +15 -15. 00 -20. 00 10. 00 Hz 100. 00 1000. 00 10000. 00 30000. 00 LF EQ The LF (Low Frequency) equaliser affects the response at the low end of the audio range.

The signal is sourced pre-fade which means that the level is independent of, and unaffected by the fader. Auxes 1 & 2 are primarily used for foldback monitoring purposes, as the fader does not affect the level. They can also be used as feeds for recording and are available sources to the USB interface for this purpose. These sends are affected by the Mute switch, so muting the channel will also mute the Aux sends. The control varies the signal level to the bus from off (fully attenuated) to +6dB, with unity gain at the arrow. There are master level controls for the Aux 1 & 2 outputs situated in the master section of the mixer. OO +6 = Auxes 3 & 4 These are post-fade sends, which means that the signals are affected by the channel fader. Primarily used for effects sends, the aux signal will reduce if the fader is pulled down so keeping the correct proportion of the effect. Muting the channel will also mute the Aux sends, and the send controls have 6dB gain fully clockwise. There are no master level controls for Aux 3 & 4 outputs. PAN L R MUTE PK ! PFL PAN The pan control adjusts how the signal from the mono input channel is shared between the left and right buses and subsequently the main stereo outputs. Set to the mid position, equal amounts of signal are fed to left and right, with pan set to L, none is sent to the Right bus. 10 5 Mute Switch 0 This mutes or cuts the signal to the left & right buses and the Aux buses. A rectangular LED illuminates to show the Mute switch is pressed. 5 10 PFL Switch & PK!LED The PFL (Pre-Fade Listen) switch sends the channel signal to the PFL bus and subsequently to the headphones and the main L R meters. Used for checking the audio signal before raising the fader or un-muting the channel. LED illuminates dimly to indicate the PFL switch is pressed, and brightly to indicate the channel signal is within 5dB of clipping. 20 30 Fader OO The 100mm fader affects the level of the channel signal to the left & right buses and Auxes 3 & 4. [. . . ] Make sure the path is ticked and click OK. Select the inputs and outputs for your tracks in your session. Here the input for mono Track 1 is selected as the Left channel from the ZED USB interface. The track outputs can either be routed to the ZED directly or to a master bus in Pro Tools and then to the ZED. [. . . ]
