AEA RPQ2, Owner'S Manual

9

connectors with Pin-2 + or high, Pin-3 – or low, and Pin-1 ground. Mic 
Input mode can be activated with the Mic/Line switch (ref. #8) in the 
OUT position. This ensures that the XLR input will route through the 
preamp gain stage, optional CurveShaper™ EQ section, and Output 
Level control. 

Line Input Mode

Line Input mode bypasses the mic preamp stage to accommodate line-
level signals. Depressing the Mic/Line switch bypasses the first gain 
stage and routes the signal from the Line Input connector straight to the 
optional CurveShaper™ circuitry and Output Level control (ref. #11). 
The illuminated green LED below the Line/Mic switch indicates when 
Line Input mode is active. Plug line level signal sources into the Line In 
connector (ref. B) located on the back panel. 

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™ EQ circuitry. To use the inserts with an effect, plug a mic 
into the XLR Input (ref. D) and take the 1/4” balanced Preamp Out (ref. 
C) into another piece of hardware such as a compressor. Connect the 
output of the compressor and plug it directly into the 1/4” Line In (ref. 
B). The standard XLR Output (ref. A) is the post-EQ output.

While in Line Mode, connecting the Line In (ref. C) directly to the 
Preamp Out (ref. B) with a 1/4” TRS cable is the same routing that Mic 
Mode does internally.  

Direct Input Mode

Engage the Hi-Z DI switch (ref. #12) to plug and play directly into the 
RPQ2’s high impedance circuit and optional CurveShaper™ EQ section. 
Each DI connector is 1/4” mono unbalanced and has a high input 
impedance of >5M Ohms which will not load down typical DI sources 
such as bass guitars, keyboards, etc. 

Depressing the Hi-Z switch (ref. #12) bypasses the first gain stage and 
routes the signal from the Direct Input connector straight to the optional 
CurveShaper™ circuitry and the Output Level control (ref. #5). The 
illuminated green LED below the Hi-Z/DI switch indicates when Direct 
Input Mode is active. There is no 48V phantom available on this input.
