2.9.1 Power Switch:
Studio R 4-ohm Z-series
amplifiers are fitted with an on/off switch located on the
front panel. In the regular use, when the switch is pointing upward, this turns the
amplifier on and two green LEDs will light up on the panel.
ATTENTION
Prior to turning your amplifier on make sure that the
power line voltage is same as selected on the apparatus.
This is statistically the only way of damaging a
Studio R
.
In addition, it is regarded as a misuse and is not covered by the warranty.
3 – INDICATORS:
The
Studio R 4-ohm Z-Series
amplifiers are equipped with LED-type light
indicators, individual for each channel, which report the user on the operating
condition. If the power is on or off, the green LEDs
“CHANNEL...ON”
will light
up. If a signal is present on the output, two green LEDs
“SIGNAL”
will flash
according to the signal on each of the channels. When the maximum output
power is reached, the blue LEDs
(Signal processing)
will light up according to the
intensity of the limiter acting and activation. See the following:
3.1 Signal processing indicators:
When the
processing blue LED
lights up, this indicates that the input signal
limitation has started. When the red LED flashes occasionally, a tolerable soft
limiting will be occurring. In case the input signal exceeds too much the input
nominal level, the limiter will start operating so as to avoid any distortions
greater than 2%.
