QSC SEQ2

The SEQ-2 is an embedded accessory that provides two independent channels of graphic equalization. Five trimpots on each channel adjust boost and cut—up to ±12 dB—at 40 Hz, 160 Hz, 630 Hz, 2.5 kHz, and 10 kHz. Each band has a Q of 0.75. Custom frequencies and values of Q are available by special order.

The accessory is compatible with PLX, DCA, CX, and PowerLight (except PL 2.4MB, PL 3.4, PL 3.8X, PL 4.0, PL 6.0PFC, and PL 9.0PFC) models fitted with an internal BusCard. It is also directly compatible with MXa, EX, and various legacy CX models. See below for a more detailed list. Because the SEQ-2 mounts inside the amplifier, once you set it you need not worry about tampering; this makes the accessory ideal to use as a default EQ in rental or turnkey systems.
