    Stereo: Connect two 1/4” phone cords to the [LEFT] & [RIGHT] INPUTS of the Wedge from a stereo source , and two 1/4” phone cords from the OUTPUTS of the Wedge to a stereo amplification system or two mixer inputs.

  • Page 11: Dry Defeat

    Turn on the power of the amplifier/mixer, and adjust the volume. Dry Defeat When connecting the Wedge to a mixing console’s aux sends and returns, it is generally desirable to remove the direct (dry) signal from the outputs of the Wedge so that its output signal contains only the effected (wet) signal.

    Press the [I/O] button. Ì Feed signal to the Wedge’s input(s). You can set the Left and Right Input and Output levels by moving the Value Sliders and Value Wheel. Your input signal should make the meters go as far to the right as possible without clipping.

    ONNECTIONS AC Power Hookup The Wedge comes with a power adapter suitable for the voltage of the country it is shipped to (either 110 or 220V, 50 or 60 Hz). With the Wedge off, plug the round end of the supplied power adapter cord into Wedge’s [POWER] socket and the male (plug) end into a source of AC power.

  • Page 21: Typical Applications

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

  • Page 22: Interfacing Directly With Instruments

    Balanced Operation The Wedge features balanced TRS inputs and outputs. This allows it to be used with professional consoles and other balanced equipment. You may need to purchase an XLR to TRS 1/4” cable or adaptor, depending on the jacks used on the connecting equipment.

  • Page 23: Interfacing To A Mixing Console

    OUTPUTS of the Wedge to a stereo amplification system or two mixer inputs. Interfacing to a Mixing Console The Wedge handles mono or stereo sends at all system levels. The input circuitry of the Wedge can easily handle professional +4 dBu levels (+20 dBu peaks), while having enough input and output gain to interface with the lower -10 dBV signal levels of home and project recording studios.

  • Page 24: Connections

    For more information about Dry Defeat, see Chapter 1. Mono In - Stereo Out: If you only want to feed the Wedge a mono input, but wish to connect both of its outputs back to the mixer, you will need three 1/4" audio cables.

  • Page 25

    Stereo In - Stereo Out: This connection is similar to the one described above. However, by utilizing two sends from the mixer, we add one more cable from a different aux send to the [RIGHT] input of the Wedge and can now send a stereo Wedge Reference Manual...

  • Page 26

    ROOM+PLATE configurations are examples of this kind of multieffect that, essentially, allow you to use the Wedge as two independent mono or stereo effect units. For this reason, we recommend using the Stereo In - Stereo Out hookup whenever possible to get the most out of the Wedge.

    Note: It is not necessary to follow step 2 if you intend to only send information to the Wedge, and do not need to receive information back from it. Example: If you only want to be able to recall Programs using MIDI program change messages, there is no need to connect a cable to the Wedge’s [OUT/THRU] connector.

    The [A], [B], [C] and [D] Sliders are used to edit parameters in Edit mode. The quickest way to edit a program on the Wedge is to press Edit and start moving the sliders. You don’t have to select a parameter before moving the slider, just grab it and the parameter will jump to the new value.

When set to off, the Wedge ignores program change messages. When set to on, incoming MIDI program change and bank select messages received on the same channel the Wedge is set to will recall the same numbered Program.

  • Page 36

    There are 128 different possible MIDI program change messages (000 – 127). However, the Wedge has 256 Programs to choose from. Therefore, the Program Table allows us to choose which of the 256 Programs will be recalled when certain program change numbers are received.

    During this time, you should feed signal to the Wedge’s inputs (i.e. play your guitar or keyboard, or playback tape). To cancel the Auto Level function once it has been engaged, press any button on the front panel.

    Classic plate reverbs often have a midrangy twang to them. Since this frequency bump is part of the character of a plate reverb, the Wedge allows you to roll off the highs (see above) and low frequencies on Plate reverbs. The High Pass Filter parameter controls the frequency where the low end will begin to roll off (at a rate of 6dB per octave).

    You can adjust the delay time using a technique called “tap tempo”. By tapping the button which corresponds to the Tap parameter, (either the TAP/AUDITION button or the [A] button), you can have the Wedge follow your tapping and adjust its delay time to match the tempo you are using.
