The EQ is bypassed when the switch is in its up position. AUX3 12 11 OO Auxes 1 & 2 Each of these controls sends a signal to an auxiliary bus. 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 all of the Aux outputs situated in the master section of the mixer. +6 AUX4 OO +6 POST PRE AUX5 POST 12 OO Auxes 3 & 4 These are switched pre or post-fade so they can be used as either monitor sends or effects sends. 13 +6 AUX6 POST Auxes 5 & 6 13 OO Sourced post fade, so that the level is set with the send control but will be affected by the fader position. Mainly used for effects. +6 Allen & Heath 17 ZED-4 BUS User Guide MONO INPUT CHANNEL = PAN PAN 14 L ODD R EVEN 14 MUTE 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, similarly to pairs of Groups. 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. 15 16 PK ! 15 PFL Mute Switch This mutes or cuts the signal to the buses and the Direct Out. A rectangular LED illuminates to show the Mute switch is pressed. 17 SIG 16 PFL Switch 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. 10 L-R M 0 17 Signal & PK!LED The Signal LED illuminates dimly at a threshold of ­16dB nominal level and gets brighter with higher level signal. The source for the signal & peak LED's is just after the EQ IN switch. LED illuminates when the signal just after the EQ IN switch is within 5dB of clipping. 18 1-2 3-4 18 20 Routing Switches The routing switches connect the post-fade signal to the mix buses via the pan control for the main LR bus and the group buses. For minimum noise from the mix bus summing amplifier, leave the switches in their up positions if the channel signal is not required on the bus. 19 30 Fader 19 OO The 100mm fader affects the level of the channel signal to the left & right, mono and group buses and Auxes 5 & 6. There is 10dB of gain at the top and the unity gain position is marked by "0". 1 Allen & Heath 18 ZED-4 BUS User Guide STEREO INPUT CHANNEL ST1 IN L 1 ST1 (& ST3) Phono sockets These are stereo inputs additional to the main stereo channel inputs (below). The gain is varied by the ST1 (& ST3) level control and these inputs can be sent to either the stereo channels or straight to the L R main bus, depending on the setting of the underpanel switch. The source for the ST3 input can be switched from the phono sockets to the USB return signal with the selector switch below the USB socket. 1 R L/M 2 Stereo Inputs 1 (& 3) Level control Adjust the level of the stereo inputs 1 & 3 from off (fully attenuated) to maximum where it has 10dB of gain. 4 ST2 IN ST1 (& 3) Routing selector switch R 3 This switch selects whether the ST1 (or ST3) signal is sent to the L R bus directly, or the stereo channel below. [. . . ] So the computer is set up to receive audio from ZED. The Output Drivers are the audio outputs from the computer. Here you can see that the pc soundcard has 4 stereo outputs (all disabled) and the software has located the USB Audio Device which is ZED. You will now be able to select your ZED USB left & right outputs as inputs to SONAR LE and be able to send audio to your ZED from SONAR outputs. In order to show how to select inputs to SONAR tracks, here is a basic Cakewalk project (. cwp). This is created by clicking File/New/Normal and then inserting a second audio track by clicking Insert/Audio Track from the main toolbar. [. . . ]
