Circuit details:

Amplifier:Attention: In the POWER 2001 module the power amplifier IC AN7591 is used as a bridge-amplifier.

Any connection from output to ground will destroy the outpout stages!

• Via the AMP_ON control line, connected to pins 6 (Stby), the power amplifiers are switched on/off by the µP.High level (approx. 4,5V): power amplifiers switched onLow level (approx. 0V): power amplifiers switched off

• Super class G - operation

The power amplifiers operate as so-called super class G - amplifiers:The supply pins 12 (Vcc) are not just connected to one fixed DC-supply as in conventional amplifiers.Dependent on the output power there are three different DC-voltages supplied to the power amplifiers:⇒ +C1 (+20V) for low output power⇒ +B1 (+29V) for medium output power⇒ +A1 (+41V for high output power

POWER 2001 Module(30 - 70W Version)

Circuit details continued:

• Low power standby feature

An additional small standby transformer, reduces power consumption in standby-mode.In case power is switched on, the control line ECO is low → relay 1210 is activated → contacts 1 and 2 are closed →transformer 5001is connected to mains. When the set is switched off (standby) the control line ECO is high → relay 1210 is not activated → mainstransformer isdisconnected. Via standby transformer and rectifiers 6210-6214 the supply voltage LOW_PWR_SUP is substituted. Thisvoltage is always available and so the microprocessor is kept running.

• DC voltages +A1, +B1, +C1

These voltages supply the Super Class G amplifier, described on previous page.The whole power supply is optimized for the special characteristic of this type of amplifier. For that reason several “tricky”details have been applied to ensure optimal efficiency and symmetrical load to the mains transformer.

Generation of +A1

Common full wave rectifying with bridge rectifier 6202, using 100% secondary winding of mains transformer (pin 10-14).

Generation of +B1

The supply for +B1 consists of one full wave rectifier:– 2 diodes of bridge rectifier 6202, with 6200(6220 in parallel) 6201(6221 in parallel) for generation of +B1using approx.70% secondary winding of mains transformer (pin 10-13 respectively pin 11-14). As example for generation of +B1 see picture 1.

Generation of +C1Full wave rectifying with 2 diodes of bridge rectifier 6202, using 50% secondary winding of mains transformer (pin 13-15/13-11).See picture 2 below.
