Spec RPA-P7EX Preamp
Input and Output
2XLR, 3RCA input / 1XLR, 3RCA (simultaneous) output
About RCA input:
RCA input signal is simultaneously transmitted to three RCA outputs and "terminal No.2" of the XLR outputs.
About XLR input:
The hot input signal received at terminal 2 of XLR input is transmitted to terminal NO.2 of the XLR output terminals and RCA output terminals simultaneously. The cold input signal received at terminal NO.3 of XLR input is transmitted to terminal NO.3 of the XLR output terminals. Each signal is selected with a mechanical selector for industrial use. Each signal is transmitted as it is via a buffer. Hot signal and cold signal are led individually to the output terminal without decoding the balance signal. This signal flow can be realized by having four amplifiers inside.
Input attenuator
A signal input to one RCA terminal and one XLR terminal can lower the level by 6 dB.
As a normal preamplifier:
Whenever the "OUTPUTS" switch is set to the normal position, the RPA-P7EX will act as a generic preamp. Please connect to the power amp you already own. The output level of the RPA-P7EX can be adjusted by the front panel volume knob.
As a PURE DIRECT CONNECTION using SPEC Power AMP.
Set the "OUTPUTS" switch to the MAX position and set the "GAIN" switch of SPEC Power AMP to the EX-VOL position or SPEC-VOL position.
Connect EX-VOL CONT terminal of RPA-P7EX and EX-VOL CONT terminal or SPEC-VOL CONT terminal of SPEC Power AMP with cable.
With this connection, the analog attenuator embedded in the power amplifier can be controlled directly from the RPA-P7EX. PURE DIRECT CONNECTION sends the signal to the power amplifier at a high level, which results in crystal clear playback quality. Experience a sensation and a level of nuance that you have never heard before.
RCU
You can control the volume with remote control.
