Purple Audio TAV 10 Band Inductor EQ (Demo Deal)

The Purple Audio TAV 10 Band Inductor EQ is a new take on the console graphic, with ten easy to use bands. Each band uses a high quality inductor and carefully selected caps to set the center frequency. At full boost and full cut the bands are narrow enough to still be useful individually, but at lower settings the bands widen out for more gentle shaping. Even at full boost and cut, the filters are shaped to be musical and useful.

An illuminated push button for relay true bypass (green) allows for easy comparison with unprocessed source material. A Tricolor LED meters the signal. With the low and high cut switched out, and all four bands set to 0, the frequency response is +/- 0.25dB from 15Hz to 25kHz, and -3dB at 60kHz.

With specialized input and output transformers, the TAV has plenty of headroom, even at full boost. The entire circuit is discrete, with no electrolytic capacitors in the signal path, and no servo amps. With only two active stages, the current draw is low enough to work in any rack, and leave plenty of juice for other modules.

Features:

• Each band boost or cut by 12dB
• Relay True Bypass
• Tricolor LED level meter
• Transformer balanced in and out
• Discrete signal path
• No electrolytic caps in signal path
• Current consumption: 60mA
• Over Current Resettable Fused (prevents any module problem from affecting your rack)
• ROHS - Lead Free

For easy serviceability and tweaking, the Purple discrete opamps can be replaced with any standard discrete opamp or a DIP-8 IC.
