AUDISON’S MEASUREMENT STANDARDS
Power measures taken according to audison standard 1998 edition.
- 12 VDC and 13.8 VDC.
- 1 kHz or crossover cut-off frequency.
- 0.3 % THD nominal power; 1% THD continuous power.
- Tolerance: +10 %; -5 %.
- Continuous power given by RMS Voltage measured on resistive load.
- The nominal power of the amplifier is measured upon a battery voltage of 12 Volts with a 4 Ohm load
and with all channels in function.

TERMINALS FOR PROTECTING CONNECTIONS; IT IS POSSIBLE TO INVERT THEIR FRONT
PANEL IN ORDER TO FIX THEM WITH HIDDEN SCREWS.
RACCORDS BETWEEN TWO AMPLIFIERS FOR PROTECTING CONNECTIONS; PROVIDED
WITH A 24K GOLD PLATED BRASS PLATE WHICH CAN BE PERSONALISED.
ANALOGUE PHASE CONTROL. CONTINUOUSLY ADJUSTABLE PHASE BETWEEN 0˚ AND 360˚, SELECTION ON THREE FREQUENCY RANGES (40-200 HZ; 200-800 HZ; 800-
4500 HZ). BY-PASS SWITCH.
ONE BAND PARAMETRIC EQUALISER WITH CONTINUOUS CONTROLS FOR: FREQUENCY (SELECTABLE IN THREE STEPS, FROM 20HZ TO 20KHZ), GAIN (-9DB, +9DB), BAND
WIDTH (Q FROM 1 TO 4). BY-PASS SWITCH.
ADDITIONAL MODULE FOR CONTROLLING SEVERAL CHANNELS. IF IT IS MOUNTED IN A FURTHER BTX2, IT CONTROLS ALSO REAR CHANNEL WITH ONLY ONE VCRDK.
GRADUAL INTERVENTION COOLING SYSTEM CONTROLLED BY THE AMPLIFIER TEMPERATURE. MIN. STARTING THRESHOLD TEMPERATURE: 44˚C; MAX. EFFICIENCY TEMPERATURE:
74˚C. IT CONSISTS OF TFC CONTROLLER MODULE TO MOUNT INSIDE THE AMPLIFIER AND TWO FANS GROUPS, TO PLACE INTO A TERMINAL OR A RACCORD.
