    QuadraVerb 2’s [POWER] socket and the male (plug) end into a source of AC power. It’s good practice to not turn the QuadraVerb 2 on until all other cables are hooked up. Alesis cannot be responsible for problems caused by using the QuadraVerb 2 or any associated equipment with improper AC wiring.

    Alternatively, you could use the INSERTS on your mixer to “patch in” only the left or right channel of the QuadraVerb 2. If using the effect sends of a mixer, you have the advantage of sending any of the mixer’s input channels to the QuadraVerb 2’s input(s), and have control over the level of each channel being sent.

    Auditioning Internal Programs You can audition the Programs in the QuadraVerb 2 by using the [VALUE/ENTER] knob or the front panel buttons, whenever the QuadraVerb 2 is in Program mode (the [PROGRAM] button’s LED will be lit). To select a Program using the [VALUE/ENTER] knob: ¿...

    “input patch cords”; i.e., you can only make a route from the destination Block. Example: To set a route from Block 2 to Block 5, you’d select Block 5 (not Block 2) using the [< BLOCK >] buttons and then select Block 2’s output as an input source.

  • Page 30: Setting The Routing Levels

    There are basically three places in the QuadraVerb 2 that can distort: at the input A/D converter, within the blocks, and at the output. The routing levels within a well-designed program are set so that none of these three will distort before the other ones do.
  • Page 31 QuadraVerb 2 provides 4 LFOs per Program. Most pitch effects use 1 LFO, but some use 2. Also, some of the larger reverb effects use an LFO for a bigger sound.

  • Page 33: Equalization

    Bandwidth is inversely related to the conventional “Q” value; that is, the higher the Q value, the lower the bandwidth. Bandwidth is used in the QuadraVerb 2 because it is a more familiar term to many musicians, and is more intuitive.

  • Page 34: Shelving Eqs

    The shelving EQs of the QuadraVerb 2 provide gains from -14dB to +14dB in 0.1dB increments. Shelving filters are well suited for applications in which high or low frequencies need to be boosted or cut, but the remainder of the audio signal is to pass through unchanged.

  • Page 35: Multiband Eqs

    Multiband EQs can be used to flexibly and accurately tailor the tonality of a signal. The 3 band and 4 band parametric EQs in the QuadraVerb 2 can be used to boost and cut multiple bands, with the added flexibility of controlling the bandwidth of one or two mid bands.

    Reverb chambers are small rooms made of the hardest, smoothest surfaces available (often marble). A loudspeaker is placed at one end, and 1 or 2 microphones at the other end. The decay time is adjusted by the distance from the microphones to the speaker and by sound diffusers placed in the room.

    Another popular trick in the 80’s was to record the reverb with the tape flipped over, so it would play backwards in the mix. It is a useful effect for drums and other percussive sounds –— it adds space without washing out the instrument. QuadraVerb 2 Reference Manual...

    QuadraVerb 2 automatically assigned the R output of the Delay to the R OUT. Since the M output of the Delay Block had originally gone to the R OUT, the QuadraVerb 2 assumed you wanted to continue having the Block go to this output. So, logically, it routed the Block’s new R output to the R OUT.
