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. [. . . ] 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. Let's choose EQ 1 MIX (this is the Mix output of our EQ, which is Block 1). This is not to be confused with EQ 1 IN MIX, which is the signal being received at the EQ Block's input. « With "EQ 1 MIX" selected, press the [VALUE/ENTER] button. Like before, the display automatically advances to page 2, and now asks us to set the level from the EQ 1 MIX output going to the Right Output. ENTER LEVEL FROM EQ 1 MIX: -6. 0dB » Turn the [VALUE/ENTER] to select a level from -48. 0dB to 0dB (100%). Press [VALUE/ENTER] button to set the level. We have now connected the output of the EQ to our Right output. Having connected both an input and output to our EQ Block, we can now hear the effect and change the parameters. 48 QuadraVerb 2 Reference Manual Making Your Own Patches - Chapter 4 Parameter Now we will choose the desired parameters for our EQ. ¿ Press the [PARAMETER] button The [PARAMETER] button's LED will light. J If the display reads "RIGHT OUTPUT SELECTED" you have not yet moved back to BLOCK 1. Press the [< BLOCK] button to move the pointer in the display to Block 1. The display will now show you the first of three pages: LOW PASS: 1000Hz GAIN: +0. 0dB These are the only two parameters on this page: Low Pass Frequency and Gain. The cursor appears beneath the Frequency setting (in the display above it is set to 1000Hz; your display may read something different). ¡ Turn the [VALUE/ENTER] knob to select a frequency between 200 and 10000Hz. ¬ Press the [PAGE >] button to move the cursor to the Gain parameter. ÷ Turn the [VALUE/ENTER] knob to set the Low Pass gain from -14 to +14 dB. Set the Gain below 0dB to "cut" or above 0dB to "boost" the selected Frequency; a setting of 0dB has no effect. Press the [PAGE >] button to advance to Parameter Page 2 of this EQ Block. The display will look like this: MID BAND: 1000Hz +0. 0dB 1. 00OCT This page has three parameters: Mid Band Frequency, Gain and Q (or bandwidth). ª Turn the [VALUE/ENTER] knob to select a frequency from 200 to 10000Hz. D Press the [PAGE >] button to move the cursor to the Gain parameter. « Turn the [VALUE/ENTER] knob to set the Mid Band gain from -14 to +14 dB. Set the Gain below 0dB to "cut" or above 0dB to "boost" the selected Frequency; a setting of 0dB has no effect. » Press the [PAGE >] button to move the cursor to the Q parameter. Turn the [VALUE/ENTER] knob to set the Mid Band EQ's bandwidth from . 20 to 2. 50 octave. Set the Q to a small number to effect the specific frequency you selected, or to a larger number to affect a wider range of frequencies centered around the selected frequency. [. . . ] Hold down [PROGRAM], [COMPARE], and [<BLOCK] simultaneously while turning on the power.
