ENGLISH
RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
DESCRIPTION
UP 2081, UP 2161 and UP 2321 are amplifiers with a (mic / line) ‘MAIN INPUT’ on either
removable connector or XLR or RJ 45 (for quick connection of an RCF BM 3001 paging
microphone through CAT5 cable) and an ‘AUX INPUT’ for music sources (e.g. CD players,
tuners, etc.).
The 3 models have identical features, but their nominal power: 80 W (UP 2081), 160 W
(UP 2161), 320 W (UP 2321).
The amplifier output is available either for low impedance loudspeakers (min. 4
Ω ) or
100 – 70 V constant voltage line (for loudspeakers having 100 – 70 V transformers).
About the ‘MAIN INPUT’:
It can have priority over the AUX INPUT (by means of an external command linked to
either the removable connector or the RJ port).
It has a ‘presence’ control and a separate high-pass filter that are useful for improving
speech intelligibility.
Front panel LEDs indicate the device state (ON, PROT), the priority activation (PRIOR) and
the signal / peak level (SIG/PK).
