dbx / 215s Graphic Equalizer

Stereo 15-band graphic EQ. Features 20mm faders. Despite its compact 1U size, it boasts smooth faders, XLR phase switching, and other specifications comparable to higher-end models. Ideal for main PA systems and stereo sources.

■Weight: 4.8 lbs. (2.2 kg) Shipping weight 6.2 lbs. (2.8kg)

■Dimensions: 1.75"" (4.4cm) H x 6"" (15.24cm) D x 19"" (48.26cm) W

■ Input Gain Control

This control sets the signal level to the equalizer. Gain is possible from -12 dB to +12 dB. The effect can be seen by viewing the output level bar graph.

■ EQ Bypass

This switch removes the graphic equalizer section from the signal path. However, the bypass switch does not affect the ""Input Gain"" or ""Low-Cut Filter.""

■ EQ Bypass LED

This red LED illuminates when the EQ is in bypass mode. Note that bypass mode only affects the graphic equalizer section. Input gain and low-cut controls remain unaffected while the EQ is bypassed.

■ Boost/Cut Range Selection Switch and LEDs

This switch selects one of two boost/cut ranges (±6 dB or ±12 dB) used by the equalizer. The red LED illuminates when a range of ±12 dB is selected.

■Output Level Bar Graph

These four LEDs indicate the equalizer's output level. The red LED (+18 dBu) is 3 dB below clipping.

■Clip LED

This red LED illuminates when the internal signal level reaches 3 dB below clipping. This can occur when any of the following occur:

1) The input signal is greater than +18 dBu

2) Excessive gain is applied by the input gain control

3) Excessive boost is applied using the frequency slider

■Frequency Band Slider Controls

Each of these sliders boosts or cuts the indicated frequency within a range of ±6 dB or ±12 dB, depending on the position of the BOOST/CUT RANGE switch. When all sliders are in the center detent (clicky) position, the equalizer output is flat.

■Low Cut Enable Switch

The LOW-CUT switch inserts or removes a 50 Hz 12 dB/oct low-cut filter from the signal path. The low-cut filter is enabled when the LOW-CUT switch is pressed.
