iv. The combination of “Size” and “Pre-delay Time” dene the reverb simulation in just two controls;

how big the room is (Size) and how far away the audience member feels they are in regard to the

performers.

. Size adjusts the theoretical size of the simulated room in short, medium, long or longer.

. Pre-delay simulates the ratio of time from the source signal to the listener to the delay of the

rst reection off the closest wall.

. A shorter pre-delay time will make the audience feel farther away from the source

. A longer pre-delay time will make the audience feel closer to the source.

v. The High Frequency parameter simulates how much high-frequency reections are in the reverb.

. Simulating the sound of a room with many metal or glass surfaces is an example of a scenario

with more high-frequency reections.

. Simulating the sound of a room with soft word or outdoor settings would be an example of less

high-frequency reections.

vi. The Low frequency parameter simulates the amount of bass building in the reverb.

. An indoor, hard surface room will accumulate more bass build-up.

. An outdoor simulation would generate less bass build-up.

vii. The Level to Mix Parameter is the amount of wet signal (or signal with reverb) that is sent back to

your main mix.

. Increasing the level to mix will create a more prominent reverb effect.

. Decreasing the level to mix will create a more subtle reverb effect.

viii. To adjust any parameter, navigate to the parameter using the MASTER/MENU knob. Press the

MASTER/MENU knob to access.

. Adjust the values by turning the knob CLOCKWISE or COUNTER-CLOCKWISE.

. Press the MASTER/MENU knob to accept these changes. Press the BACK button to cancel

these changes.

c. Delay - The FX Processing Delay is designed to be a musically oriented delay, commonly used on rock and

ballad vocals and guitars. It is often set to match the specic “Beats Per Minute” (i.e. “BPM) of the song

currently being performed, plus how many delay returns are desired per beat, how long the delay keeps

returning and if the delay feeds back again multiple times.

i. “On/Off” When set to off, the Delay input is disabled. This allows the current signal to “ring out” until

the current delay signal is completed. To end the delay immediately, turn down the Delay Level to Mix

fader.
