User manual ALESIS QUADRAVERB2

[. . . ] ALESIS QuadraVerb2 Reference Manual Introduction Thank you for purchasing the Alesis QuadraVerb 2 simultaneous effects processor. To take full advantage of of the QuadraVerb 2's fuctions, and to enjoy long and trouble free use, please read this user's manual carefully. How To Use This Manual This manual is divided into the following sections describing the various modes of the QuadraVerb 2. Though we recommend you take time to read through the entire manual once carefully, those having general knowledge about effects devices should use the table of contents and index to reference specific functions while using this device. If you are planning to use the Alesis optical digital I/O, read chapter 7 carefully. [. . . ] Each Block can be modified according to the available parameters (based on the Block's "type"), and routed independently of the other Blocks. ¿ Press the [TYPE] button. The [TYPE] button's LED will light . ¡ Press the [< BLOCK] button repeatedly until the pointer is above the leftmost Block in the display (this is Block #1's position). The display will show page 1 of Type mode (there are 3 pages in this mode): BLOCK 1 FUNCTION: OFF ¬ Turn the [VALUE/ENTER] knob to select EQUALIZATION as the Block Function. The function will flash until you press the [VALUE/ENTER] button. ÷ Press the [VALUE/ENTER] button. The EQ module will now be displayed as Block 1, and the display automatically advances to Page 2. EQ TYPE: LOWPASS FILTER Turn the [VALUE/ENTER] knob to scroll through the various EQ effect types. By rotating the dial we can also see various Shelving, Parametric, and Graphic types of EQs. Let's select a 3 Band Parametric EQ. EQ TYPE: 3 BAND PARAMETRIC EQ ª Press the [VALUE/ENTER] button. The EQ type will now be selected for Block 1, and the display will move back to Page 1 of the Type function. 46 QuadraVerb 2 Reference Manual Making Your Own Patches - Chapter 4 Routing Routing is the Function used to connect audio between the LR IN and the Effect Blocks and the LR OUT. We must route audio to both the inputs and outputs of our EQ Block in order to hear its effect. Routing is always done by selecting the destination (where you want the audio to go to) and assigning it a source (where you want the audio to come from). After making a connection, you can then adjust the level of the source's signal. ¿ Use the [< BLOCK >] buttons to select the EQ Block we just created. If you just finished the previous tutorial, the EQ Block should already be selected. The IN LR is not selectable as a Block. J ¡ Press [ROUTING]. The [ROUTING] button's LED will light and the display will read: ADD ROUTE FROM: INPUT LEFT The cursor appears under the setting (INPUT LEFT) which is flashing. ¬ Turn the [VALUE/ENTER] knob to scroll through the various options. The choices are INPUT LEFT, INPUT RIGHT or EQ 1 MIX. As you scroll through, notice the flashing "patch cord" which appears in the lower display connecting IN L to EQ IN or IN R to EQ IN or M out to EQ IN, depending on which option you are viewing in the upper display. All three options are routed to the EQ Block's input, so their nomenclature is determined by their source, i. e. FROM INPUT LEFT, FROM INPUT RIGHT, etc. ÷ With the "INPUT RIGHT" option selected, press the [VALUE/ENTER] button. This connects the signal from the Right input of the QuadraVerb 2 (IN R) to the input of the EQ module. Upon pressing the [VALUE/ENTER] button in step 3, the display automatically advances to Page 2, which is where we may set the level of this connection (the volume from the right input to the EQ in). The display now reads: LEVEL FROM: INPUT RIGHT = -6. 0dB The patch cord will still flash until a level has been dialed in. J Turn the [VALUE/ENTER] knob to select the input level for this connection. Level Setting The input level is an important parameter, the setting of which can have a drastic impact on the resulting effect. It's default setting of -6. 0dB represents the "halfway" point of its range. 0 dB is the loudest using no attenuation, while OFF mutes the route entirely. You should set the level to accommodate the headroom the effect will need. For example, even if the front panel input levels are below clipping, if you boost an EQ band, it can distort the internal processor of the Q2. The -6. 0 dB setting will accommodate most blocks, but if there is clipping internally (when the red LED's flash QuadraVerb 2 Reference Manual 47 Chapter 4 - Making Your Own Patches on input), lower the input level. You may also need to lower the routing level if a block is receiving signal from more than one source. On the other hand, the best signal-to-noise ratio is achieved when signals are as loud as possible without clipping. In the case of a one-block program, the routing from the block to the L and R outputs should be at 0. 0 dB. Multiple-block programs will need lower settings to avoid clipping at the output blocks. ª Press the [VALUE/ENTER] button to set the level from -48. 0dB to 0dB. D Press the [BLOCK >] button to move the pointer to the OUT R Block. The OUT L and OUT R are selectable as separate destination Blocks. The display will flash: J ADD ROUTE FROM: EQ 1 MIX Note that the flashing patch cord now connects the EQ1 M to the OUT R and if we turn the [VALUE/ENTER] knob, we can see the following possible input sources for the right output: ADD ROUTE FROM: EQ 1 IN MIX ADD ROUTE FROM: INPUT LEFT Note that the route from Input Right can't be added, because it's already there as part of the default patch #99. As we scroll through the various input sources, the display will flash each one's patch cord while selected. [. . . ] This will reset all Global parameters to their default settings, and will initialize the edit buffer so that the current Program is set to its default settings (no Blocks/routings). However, none of the Programs in the User bank or the Preset bank are changed when re-initializing the unit this way. Total Reset A more drastic version of re-initializing the QuadraVerb 2 will erase all User Programs, as well as resetting all Global parameters. Hold down [PROGRAM], [COMPARE], and [<BLOCK] simultaneously while turning on the power. Maintenance/Service Cleaning Disconnect the AC cord, then use a damp cloth to clean the QuadraVerb 2's metal and plastic surfaces. For heavy dirt, use a non-abrasive household cleaner such as Formula 409 or Fantastik. [. . . ]
