[. . . ] CAUTION Changes or modifications to this equipment not expressly approved by TEAC CORPORATION for compliance could void the user's authority to operate this equipment. For the consumers in Europe WARNING This is a Class A product. In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures. Pour les utilisateurs en Europe AVERTISSEMENT Il s'agit d'un produit de Classe A. Dans un environnement domestique, cet appareil peut provoquer des interférences radio, dans ce cas l'utilisateur peut être amené à prendre des mesures appropriées. [. . . ] Note also that there are two modes for the first 48 channels--input and return modes--similar to the channel modes found on many recording mixers, allowing replay and mixing of recorded tracks without physical repatching. As with many such recording mixers, the "return" has fewer features than an input source, and these are shown in the table below.

Depending on current surround setting b. Aux 1­2 only The level of all modules is controllable via faders, and adjacent odd-even pairs of all modules can be linked (except for the stereo buss, of course). The operation of all these modules is almost identical and so they are described together here, with appropriate notes when a feature only appears on certain channel modules. · As well as the physical insert points described in "Channel inserts" on page 49, the EQA-20 also includes "soft" inserts, which allow the interconnection of internal components for more complex recording and mix situations ("Insert patching" on page 61). 58 TASCAM EQA-20 User's Manual 4 ­ Routing & assignment : Routing · Assignment of modules to the 24 busses as well as to the stereo busses is carried out by dedicated keys (to the left of the display). · Assignment of physical hardware inputs to modules, and of internal components to physical hardware outputs, together with the internal patching between mixer sections, as well as the setting up of the "soft" inserts, is done in the ASSIGN screens (see "Routing" on page 59). Routing Use the ROUTING screens to set up the routing of input sources to modules, etc. There are four of these screens: one for INPUT, one for OUTPUT, one for the OUTPUT SLOTs and one for the soft INSERTS. To enter these screens, press the ROUTING key (ALT + 6) until the appropriate screen is shown on the display. NOTE Assignment of channels to busses is done by means of the buss keys to the left of the display, or by means of the ASSIGN screens (use the ASSIGN key here). Input routing The INPUT screen allows you to select input sources from a list composed of (mainly) the physical inputs of the EQA-20, and route them to input destinations (channels and dynamics triggers). The eight analog assignable returns (see "Analog inputs" on page 33). EFF RTN The internal effect returns (see "Insert patching" on page 61). 2TRIN The 2-track master recorder inputs (see "2 TR IN" on page 49). OSC Internal oscillator SLOT1/SLOT2/ The inputs provided by any cards fitted to the SLOT3/SLOT4 slots (see "Slot card configuration" on page 52 for details). LOOPBACK Explained below ("Loopback options" on options page 60). The display shows Bx/Dy (x can be from 1 through 24 and is repeated twice, while y is from 1 through 48, e. g. B1/D25) or BUSS 1 through BUSS 24 or AUX 1 through AUX 12 or STEREO L or STEREO R when a loopback routing is selected. When a channel has a direct output selected, the direct output from that channel overrides the correspondingly-numbered buss. The direct option allows the selection of only the direct module outputs (1­48) as sources. Note that the selection of DIRECT as a channel destination, using the selection keys, removes the channel from the busses. WARNING Flipping the channels It is possible to "flip" individual channel inputs between the input and return sources (so that the "input" source becomes the "return" and vice versa) on an individual basis within the MODULE screens (see "INPUT/RETURN selection" on page 83), but it is sometimes convenient to be able to do this for batches of eight channels at a time. This is done from this INPUT screen using the BATCH SETUP at the bottom of the screen. Of course this can As the name of these loopback options suggests, they allow flexible internal repatching, which could result in a loop whereby the output of a buss also acts as an input to the same buss, resulting in a feedback loop. When monitoring, this can result in damage to hearing and monitoring equipment. Before using these options, we suggest that you work out on paper what exactly you are trying to achieve, and it may help if you draw a diagram to help you work out the ultimate sources and destinations of the routing in your system. Digital input selection At the bottom right of this screen, the physical connector (XLR or RCA) for each of the stereo digital inputs can be selected. 60 TASCAM EQA-20 User's Manual 4 ­ Routing & assignment : Routing Output routing The output routing screen allows you to tie the logical outputs from the different parts of the EQA-20 to the physical output ports. Use the POD 4 control to select the output source. Select from: · ALL (all of the output sources mentioned below) · BUSS/DIRECT The 24 busses, and any direct channel outputs · AUX The 12 aux sends · STEREO The stereo buss There is a second selection called INPUT BYPASS, which allows you to select the same input sources as for input routing (see "Input routing" on page 59). These inputs are routed directly to the selected outputs, just like a patchbay. TIP Figure 4. 2: Routing outputs There are two such screens, one dedicated to the built -in outputs of the EQA-20, and the other dedicated to the outputs provided by any optional cards fitted in the slots.
