MEASURED SPECIFICATIONS: CPS3 entire unit
Measurement conditions, unless differently specified:
• tolerance of measured values:
∆
X = ±1.5 dB
• measuring frequency: f = 1 kHz
• stated levels refer to: U = 775 mV (0 dBu)
• level controls set to their clockwise limits
• pin assignment of the XLR-type connectors: PIN 1: GROUND
PIN 2: + INPUT
PIN 3: - INPUT
• source resistance for the induction via the XLR-type connector: R(Q) = 50
Ω
• MAIN-PCB numbers relate to the models as follows:
MAIN - PCB
CPS3 / 120 V 86212
CPS3 / 230V 86208
• MAIN-PCB and POWER-AMP-PCB are provided with service connectors.

1. Operating voltage: U(B) = 100V/ 120V/ 230V/ 240V
depending on the model: 50Hz ... 60Hz
2. Deviation limit of the operation voltage: ±10%
3. Power consumption (both channels driven):
3.1. at idling condition P(B) = 140 - 200 W
3.2. at standard operation (80W/4
Ω
) P(B) = 1000 W
3.3. at nominal condition (800W/4
Ω
) P(B) = 2950 W
3.4. at 1/8 of the nominal power (100W/4
Ω
) P(B) = 1100 W
