Page 4: Introduction
With phantom power disengaged, the NoLoad™ input impedance at 63K Ohms means the RPQ2 won’t load down a mic and change its sound. The RPQ2’s CurveShaper™ EQ gives you the tools to control your ribbons right at the start of the signal path. -
Page 5: Front Panel Guide
FRONT PANEL GUIDE 1- Mic/Line switch: OUT is Mic Input mode; IN is Line Input mode which bypasses the mic preamp stage to accomodate line-level signals. The LED below the switch will indicate when the Line Input mode is engaged. 2 - Mic Gain rotary switch: This twelve-position switch selects from +13dB to +62dB of preamplifier gain, as measured between the XLR input and the 1/4”... - Page 6 7 - Low Frequency Filter control: This continuously variable control adjusts the -3dB break-frequency of the filter from 22 Hz to 515 Hz; maximum LF reduction is -20dB. 8 - High Frequency (HF) In switch: OUT is true bypass; IN inserts the CurveShaper™ circuitry. The green LED below switch will indicate when HF boost is engaged.

REAR PANEL CONNECTIONS A- Balanced Output - XLR: Female three-pin XLR: pin-1 is ground, pin-2 is high (+), and pin-3 is low (-). B - Balanced 1/4” Line In Input: Line Input mode connector. Bypasses the mic preamp gain stage to accommodate line-level signals. -

1) Mic preamp routed into optional EQ. 2) Line level stand-alone EQ. 3) DI routed into optional EQ. Each RPQ2 channel provides an XLR input (Mic Input mode), a 1/4” front panel unbalanced DI, and a back panel Line In 1/4” connector (Line Input mode). -
Page 9: Line Input Mode
Line Input mode allows you to insert compressors or other effects between the preamp and CurveShaper™ EQ section. While the Mic/ Line switch is depressed, the preamp section of the RPQ2 is still active; however, it is independent of the Output Level control and CurveShaper™... -

XLR and are not using the direct input, check if the DI switch is engaged. The output of the RPQ2 emulates a transformer-coupled output and can be used as either a balanced or unbalanced signal (depending on how your cable/system is configured). -

Page 12: Line And Direct Input Mode
Using the LF Filter The RPQ2 was designed to complement ribbon microphones. AEA Big Ribbon™ mics deliver sub-woofer lows, which the RPQ2 renders faithfully. Such strong low-frequency content can mask high-frequency intelligibility, so the tunable low-frequency (LF) filter was engineered... - Page 13 “P-pops” and breath-noise. However, a fixed-frequency, constant slope low-cut filter cannot handle all situations effectively. The RPQ2 offers a flexible LF filter that can be tailored to satisfy the varying and critical demands of both speech and music.

Page 14: Using The Hf Curveshaper™ Eq
Using the HF CurveShaper™ EQ The RPQ2 features a unique CurveShaper™ circuit that enables you to add a little extra “presence” or “air” to compensate for high-frequency losses that are inherent to most ribbon microphones, the result of distant mic placement, or to restore presence in a “dry” acoustical environment. - Page 15 Note: When the Curve Gain is fully counter-clockwise (set in the “0” position), no EQ will be introduced into the signal. It essentially the same as having the HF In Switch (ref #8) disengaged.
