RCF S.p.A. would like to thank you for having purchased this product, which
has been designed to guarantee reliability and high performance.
The PR 4092 preamplifier has been specifically designed for the public broadcasting of
announcements and/or musical programs in all audio systems. Each of the 9 inputs can
be sent to output “A” only, to output “B” only, or to both. The equipment can therefore
be used as a double preamplifier (for example: output “A” reserved for microphone
announcements; output “B” reserved for background music). Input no. 1 has absolute
priority (activated both by means of a contact and by the presence of a signal); inputs nos. 2
and 3 can be given priority over the subsequent inputs; an input’s priority function is active
only at the output selected (or both).
- 1 microphone input (no. 1; XLR connector) with absolute priority activated both (auto)
in the presence of a signal (VOX) and by contact; signal indicator (LED)
- 8 universal inputs, each with MIC / LINE selector and signal indicator (LED), located on
the front panel:
inputs nos. 2, 3, 4, and 5, with XLR connector (MIC / LINE)
inputs nos. 6, 7, 8 and 9, with XLR connector (MIC) and double RCA (LINE)
- “Phantom” feed (can be inactivated by group) at the microphone inputs - 2 balanced
outputs with XLR connector - double “REC” output (double RCA connector)
-
inputs 2 and 3 given priority over subsequent inputs by means of vocal activation
(excludable)
-
warning signal (3-tone) activated by means of contact (input 1) or the “CHIME TEST”
button the front panel - level control (with VU meter) for each of the two outputs
-
bass- and treble-tone control for each output
- alternating-current power supply (230 V - 50 Hz / 115 V - 60 Hz)
- direct current power supply (24 V).
CHIME. Pressing the “CHIME TEST” button sends a warning signal (3-tone) to the output
selected, making it possible to regulate its level by means of the relative volume control.
VOLUME CONTROL (CHIME, INPUTS 1÷9). Makes it possible to set the signal level of
the relative input.
Note:
the level must be regulated so that the signal is optimal at the
output selected but without the peak indicator (read LED “PEAK”) lighting up.
