Line Input Mode; Direct Input Mode - AEA RPQ2 Owner's Manual

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.
