PreSonus RC 500 1-Channel Channel Strip
PreSonus RC 500 1-Channel Channel Strip
The RC 500’s 3-band semi-parametric EQ was designed to match the preamp and compressor. It combines isolated filters and optimized, per-band Q to provide subtle signal-shaping without harsh artifacts.
Features:
- Transformer-coupled, high gain microphone preamp with a Class A hybrid design
- FET based compressor using hybrid detection methods with switching relays for hard bypass
- 3-band semi-parametric equalizer with switching relays for hard bypass
- +48V phantom power, 80 Hz highpass filter, and -20 dB pad
- Front-panel 1/4″Â instrument and rear-panel XLR microphone and line inputs with Input Select switch
- VU meter with selectable output level/gain reduction display
- Analog insert with balanced send and return
- High grade components: film capacitors, 1% tolerance resistors, and very low-distortion op amps
- Master output control
- Balanced output on XLR and 1/4″TRS connectors
- Internal toroidal power supply with IEC connector
- Steel chassis
