Description
RDL ST-EQ3 - 3-Band Line-Level Equalizer
The RDL ST-EQ3 is a compact, active 3-band audio equalizer designed for precise adjustment of low, mid, and high frequencies in line-level signals. It is ideal for professional AV installations requiring tailored audio response for voice or music applications.
The module features a high-impedance balanced bridging input, which can also be wired unbalanced. The 150Ω balanced output is suitable for driving balanced or unbalanced lines of 150Ω or higher. Equalization is achieved through three active bands centered at 80 Hz (low), 1 kHz (mid), and 30 kHz (high). A peak overload LED indicates excessive signal levels before or after EQ, aiding in setup.
Functionality
- 3-band equalization for line-level audio
- Independent control of low, mid, and high frequencies
- Voice-band shaping or smile-curve EQ for music
- Balanced or unbalanced input/output
- Peak overload LED for signal monitoring
- Compact STICK-ON form factor for easy AV integration
- 24 V DC ground-referenced power
