Page 6: Unpacking
Proper lifting requires at least two people. DO NOT attempt to lift the Nº433 from its packing carton alone. DO NOT attempt to lift the Nº433 while bending at the waist. When lifting, stand as straight as possible using the leg muscles to lift. -
Page 7: Installation Considerations
“Power Requirements” on page 9 before installing the Nº433. • DO place the Nº433 on a solid, flat, level surface such as a table, shelf, or floor OR bolt the Nº433 into a rack-mounting system. Use a purpose-built rack-mounting system to accommodate the weight of the power amplifier. - Page 8 Note • DO NOT place the Nº433 on a thick rug or carpet or cover the Nº433 with a cloth, as this might prevent proper cooling. If the Nº433 is placed on the floor, use a thick piece of tempered glass to provide firm support and proper ventilation.

Page 9: Power Requirements
Nº433 Power Amplifier Power Requirements When shipped, the Nº433 is configured for 100V, 120V, 220V, 230V or 240V AC power operation at 50 or 60Hz based on the country for which it is manufactured. Before operating the Nº433, make sure the ~ac mains connector label indicates the correct operating voltage for the current location. -
Page 10: Operating States
When power returns, the Nº433 will require a brief warm-up and break-in period (not the full 300 hours). It is recommended that you allow the Nº433 and other audio components to stabilize for a few minutes. Operating States The Nº433 has four operating states:... -
Page 11: Special Design Features
Nº433 Power Amplifier Special Design Features Thank you for purchasing the Nº433 Power Amplifier. While this amplifier is straightforward in everyday use, it includes several design features that are responsible for its outstanding performance. In particular, this amplifier defies the accepted wisdom that it is impossible to design a large, powerful amplifier that also has all the finesse of the finest smaller amplifiers. -
Page 12: Extensive Protection
Extensive Protection The Nº433 is designed to shut itself down if it senses any of a number of fault conditions that could cause damage to itself or to associated loudspeakers. These fault conditions include: • the presence of DC (direct current) at the output •... -

“Unpacking” on page 6 for additional information. DO NOT attempt to lift the Nº433 from its packing carton alone. DO NOT attempt to lift the Nº433 while bending at the waist. When lifting, stand as straight as possible using the leg muscles to lift. - Page 16 If the associated preamplifier does not support balanced connec- tions, connect the RCA output on the preamplifier to the RCA input on the Nº433. To reduce the chance of noise at the (otherwise un- terminated) inverting XLR input, insert the supplied U-shaped shorting-straps between pins 1 and 3.
- Page 17 Pin 3: Signal – (inverting) Connector ground lug: chassis ground Before making balanced connections, remove the U-shaped shorting- straps between pins 1 and 3 on the Nº433 XLR inputs and save them for possible future use. Shorting-straps are installed when the Nº433 is shipped.
- Page 18 Make sure power is disconnected from the ~ac mains connector before making adjustments. When the power save mode switch is set to on, the Nº433 powers on in sleep mode. If the Nº433 is configured for trigger control, incoming DC signals toggle the Nº433 between on and sleep mode.
- Page 19 Do not defeat the “third pin” or “earth ground” of the power cord. The Nº433 includes internal fuses as a final stage of protection. The protection circuitry is designed so that only a catastrophic failure will cause the fuses to blow.

• Use a six-conductor cable (six-pin RJ-11 plug to eight-pin RJ-45 plug) when connecting the Nº433 to a Nº320S or Nº326S pream- plifier. (Pins seven and eight are not used on the eight-pin RJ-45 plug.) •... -
Page 22: Creating A Slave Chain
Must include components that are connected in a certain order to prevent communication from prematurely terminating. Power amplifiers such as the Nº433 must be the last component in a slave chain. The slave chains in this section include preamplifiers and power amplifiers. - Page 23 The power amplifier is not connected. To create a slave chain that includes the Nº433: 1. Make sure the Nº433 and all associated components are powered off. 2. Connect the input communication port on the first power...
