REVERB PARAMETERS

Use the [CURSOR ] button to move the cursor to the lower line of the display, and turn the [VALUE] knob to advance the display through the remaining pages of the Reverb function. However, you must have the correct effect send selected (1–4) in order to get at the Reverb parameters (in Config. #1, the Reverb parameters are found only on effect send 1; in Config. #2, they are found on sends 1 and 3 since there are two separate Reverbs). Here you will find parameters for selecting the Reverb type, adjusting Pre-Delay Time and Pre-Delay Mix.

Reverb Type (7 types) Page 5

The QSR has seven different reverb types, all stereo, each of which simulates a different space or produce a different ambient effect. The different Reverb types are:

Plate 1 & 2. The two Plate reverb types simulate an artificial device known as a Plate. In the early days of recording, Plates were extremely popular because they were almost the only way to provide any sort of artificial ambiance to a recording. The sound of a well-tuned Plate has become quite popular over the years especially when used on vocal or drum sounds. The two Plate reverbs differ in subtle tonal characteristic changes such as those found in different manufacturers’ plate reverbs.

Room. The Room reverb type simulates not only rooms of different sizes, but rooms with different surface materials. A room with soft surfaces such as carpet will produce a reverberant sound with much less high end (treble) than a room with hard surfaces. This reverb type can easily simulate both examples and many, many more.

Hall. Much larger than a room, Halls are characterized by their high ceilings, irregular shapes, and generally uniform density of reflections.

Large. Much larger than a hall, this reverb type emulates large ambient spaces such as amphitheaters, gymnasiums, etc.

Gate. Gated Reverb is a very popular effect on drums first found on English records in the early 1980s. This reverb type can simulate applying a noise gate (a device that automatically decreases the volume once the signal falls below a certain level) across the output of the reverb thereby causing the initial attack of the reverb to sound very big, but the tail of the reverb to be cut off very quickly. Although this effect is not found in nature, it works great for modern drums, percussion, and any quickly repeated, transient source.

Reverse. The Reverse Reverb type is an inverted reverb in which the volume envelope is reversed. This means that the signal begins softly but grows louder until it is cut off, rather than loud to soft as normal.

Pre-Delay Time (0 to 299ms) Pages 6 & 7

Pre-Delay is the slight delaying of the Reverb itself so that the dry signal more easily stands out from the Reverb. A bit of Pre-Delay can sometimes make certain instruments (such as snare drums) sound bigger. Use page 6 to adjust the Pre-Delay Time in 10ms intervals, and/or use page 7 to adjust the Pre-Delay Time in 1ms intervals. This Pre-Delay is part of the Reverb itself; don’t confuse it with the separate Delay modules available under the Delay function.
