408S 808M 808S Two types of power transformer are used, one for the 406M, 408M and 408S and one for the 808M and 808S. All models use the same effects board and output board. There are two different amplifier boards (800 watts and 400 watts), three different mixer boards (8 channel Mono, 8 channel Stereo and six channel Mono) and two types of AC power board (one for the 800 watt models, one for 400 watts). -

Page 10: Amplifier Theory
808M/808S Power Amplifier Theory of Operation The power amplifier used in the 800 series powered mixer is typically referred to as having a high efficiency output stage. It uses a Class-H topology. When signal levels are low, one can pull power from the +/-45V supplies. Only when signal levels are high is current pulled from the +/-90V supplies. - Page 11 Referring to the channel-1 switching circuit shown here. There are two pairs of jumper resistors. The first pair (R121, R106) allow both class-H switches to operate in tandem. When operating in tandem, if the positive switch actuates, the negative switch also does, and visa versa.
- Page 12 R104 (Both 2.2K ohms) allowing around 1.4mA to flow into pin-12. This current flows out of pin-3 and approximately half of it flows through D38 / R83 and the other half to the emitter of common base amplifier Q34. The current flowing in the collector of Q34, pulls the high side of R120 to ground potential, allowing again around 14V to be dropped across R120.

Page 13: Safety Test
Safety test You must perform the following leakage test before returning the mixer to your customer. Take every safety precaution to protect yourself while doing this test. 1. Make a small loading RC circuit as shown in the diagram below, and connect the AC volt meter between the AC power source ground and any exposed metal on the unit under test. -
