Page 6: Dig In/Out Channels. When using the Alesis Optical DIGITAL [IN] connector, (Input Audio Source must be set to ÒOPTICAL DATAÓ, see above), this page allows you to select which of the 8 channels on the optical buss will be routed to the L and R IN. Both inputs can be set to receive any channel on the buss, from 1 to
8.You can even route the same channel to both inputs. Since the Q20 has two outputs (left and right), you get to chose which of the 8 channels on the outgoing optical buss they should be sent on. Both outputs can be routed to any channel on the buss, from 1 to 8. However, you cannot assign both outputs to the same channel on the optical buss. For the outputs to be routed at all, the Digital Output Mode must be set to ÒNORMALÓ (see below).
DIG CH IN: L=1,R=2 OUT: L=1,R=2
Note that the front panel meters only monitor inputs 1 and 2, and the analog outputs will work only if the output channels are set to 1 and 2.
Page 7: Digital Output Mode. This determines how the ADAT DIGITAL [OUT] connector will function. When set to ÒNORMALÓ, the Q20Õs L/R OUT is routed to the DIGITAL [OUT] connector. When set to ÒTHRUÓ, whatever is received at the DIGITAL [IN] connector is passed on to the DIGITAL [OUT] connector without any processing occurring on the digital signal within the Q20. Use this mode when you are connected between to Alesis Optical devices (such as ADAT) between which you wish to bounce digital audio.
DIGITAL OUTPUT MODE: NORMAL
Page 8: Tap Tempo Footswitch. This lets you choose which footswitch jack (either [ADVANCE] or [BYPASS]) will be used to provide a tap tempo source for setting delay time, provided the selected Program uses one of the two available tap tempo delay types. This requires that you have defined an Effect Block as one of the two Tap Tempo delay types, and that the desired footswitch jack has been selected for controlling tap tempo.
Page 9: Global Direct Signal. The purpose of this feature is to satisfy the conditions of a recording studio environment. When connecting the Q20 to a mixing consoleÕs aux sends and returns, it is generally desirable to remove the direct signal feed from the outputs of the Q20. Since most Q20 Programs route the L/R IN signal to the L/R OUT, you will need to remove this connection from the ProgramÕs routing when connecting to a mixerÕs aux sends and returns. However, this can be done globally for all Programs using this function. If it is set to ÒONÓ, the inputs will be heard at the outputs, if the are routed this way in the current Program. By setting this function to ÒMUTEÓ, you can remove this connection for all Programs without having to delete the Òpatch cordsÓ in each that route the inputs to the outputs.
GLOBAL DIRECT SIGNAL: ON
When set to ÒMUTEÓ, recalling a Program which has the L/R IN routed to the L/R OUT will not display those Òpatch cordsÓ so as to avoid confusion. You can, however, still add or delete these connections, as well as adjust the Direct Signal Level in Mix mode, and these changes will be remembered when you store the edited Program. However, as long as the Global Direct Signal function is set to ÒMUTEÓ, you will not hear the effect of any of these edit.
