AIR Filter

10. LEVEL

The AIR filter is a unique feature that restores brilliance and sizzle to compressed signals. It provides a high-frequency boost to the signal after the compression stage. It ranges from OFF to FULL, where FULL provides the maximum high-frequency boost.

LOOK	Certain instruments such as
	vocals, acoustic guitars, and brass
	instruments have a wide dynamic
	range. A musician uses this dynamic
CLOSER	range to accentuate the “feel”
	of a particular section in a song.

Compression is the key to balancing these dynamic signals in a live sound system so they don’t jump out in the mix during hard hitting sections or get lost in the softer passages.

Unfortunately, compression also tends to dull an instrument’s sound, and the sound, although more balanced, loses its sparkle.

The AIR filter is a high-frequency shelving filter whose amplitude varies depending on the amount of compression applied to the signal. When softly compressing the signal, the AIR filter provides very little high-frequency boost (it’s not really needed). When squeezing the signal hard with compression, the AIR filter has more high-frequency boost available.

This makes the AIR filter a great tool for live sound. Experiment with the AIR LEVEL control to find the best sound for the particular instrument or voice being compressed.

11. GAIN REDUCTION Meters

These 8-segment meters indicate the amount of gain reduction that is applied to the signal by the compressor. It ranges from 1 to 30 dB of gain reduction.

When the signal is below the threshold and there is no compression taking place, there is no meter indication. As soon as the signal crosses the threshold and triggers the compressor, the meter LEDs begin to light from right to left, indicating more and more compression.

12. POWER Switch

Use this switch to turn the SQ•2 on and off. The LED above the switch lights when the power is on.

13. Line Cord Socket and Fuse

Here is where you connect the detachable line cord that came in the box with your SQ•2. Plug the other end of the line cord into an AC outlet properly configured with the voltage required for your particular model (see AC Select Switch next).

The fuse is located behind the fuse cover, at the bottom of the IEC socket. See the “Troubleshooting” section on page 12 for information about replacing the fuse.

14. AC Select Switch

Set this switch to the correct voltage setting for the country you are in, 115 VAC or 230 VAC.

Note: The SQ•2 is shipped with the AC Select switch set to the 230 VAC position. If you are in a country that uses 100-120 VAC, remove the cover plate with a phillips-head screwdriver and set the switch to the 115 VAC position. A 315 mA fuse

is used for both voltages (115V/230V). See the

“Troubleshooting” section on page 12 for instructions on replacing the fuse.
