AEA RPQ500 Microphone Preamp 500 Series Module

LED Indicators

- Green, yellow, and red LEDs indicate levels at -20, 0, and +24 dBu

Curve Gain

- This continuously variable control adjusts the HF gain from flat (+0 dB) to maximum (approximately +20 dB); the slope of the CurveShaper EQ varies as Curve frequency and gain settings interact

Curve Freq

- This continuously variable control adjusts the +3 dB break-frequency from 2.5 to 30 kHz

HF Switch

- Out is true bypass; In inserts the CurveShaper circuitry

LF Switch

- Out is bypass; In inserts the -20 dB low-cut shelving filter

Low Freq Cut

- This continuously variable control adjusts the -3 dB break frequency of the filter from 22 to 515 Hz; maximum LF reduction is -20 dB

P48 Switch

- Out is off; In applies full-spec P48 phantom power to the input (indicated by the red LED near the switch)

Mic/Line Switch

- Out is Mic Input mode; In is Line Input mode (green LED on), which bypasses the mic preamp stage to accommodate line-level signals

Polarity Switch

- Out is normal; In is inverted

Mic Gain

- This 12-position switch selects from +13 to +62 dB of preamplifier gain

Output Level

- This continuously variable control provides up to +19 dB additional output gain in Mic Input Mode (following the optional CurveShaper circuitry); it acts as a fader and allows -60 dB attenuation of the output signal (0 dB unity is one tick below +6 dB)

- One channel with 81 dB of sweet and quiet JFET gain

- High-frequency CurveShaper EQ and low-frequency proximity control

- Mic and line inputs for mixdown EQ versatility

- Switchable phantom power, polarity, and mic/line input mode

- NoLoad 10-kilohm high-impedance circuitry providing better overall transients, frequency response, and higher output sensitivity

- Made in the USA
