UP 4240 is a 240 W amplifier having 2 audio
inputs. The MAIN INPUT has a gain selector
(MIC, MIC with PHANTOM power supply,
LINE) and can have priority through a contact
or the automatic signal detection (VOX
function). The MAIN INPUT priority function
entails the AUX INPUT attenuation (without
priority, the 2 inputs are mixed together).
AUX INPUT has ‘line’ gain for audio signals
coming from preamplifiers, music sources
(e.g. CD / MP3 players, tuners, etc.). The
loudspeaker output is available for either a
low impedance (min. 4 O) connection or a 100
– 70 V constant voltage line (for loudspeakers
having matching transformers). BASS and
TREBLE tone controls are available on front
panel, as well as LEDs to indicate its operation
(ON), protections (PROTECT) and audio
signal level.
