Configuration 4. Configuration Amplifier operational configuration is set up through selections made on a rear mounted DIP switch module. A GPIO (General Purpose In/Out) connector is also provided that enables access to a variety of amplifier control and monitoring functions. 4.1 DIP Switch Configuration The DIP switch module is illustrated and its functions described for two and four channel amplifiers in the adjacent matrices. DIP switch options are selected (ON) when the switch is in the UP position.
Configuration 4.2 GPIO Functions 1 The GPIO connector is illustrated and its functions described in the adjacent matrix. 2 3 4 5 GPIO GND (1) Note: The GPIO connector must not be used for any unintended purpose. Amplifier damage may result from incorrect use of GPIO. NOTES Ground reference for all GPIO pins Channel 1 & 2 additional gain control. Connect to a potentiometer (>10kΩ) wiper between the VCC and GND pins. Diagram 2a below illustrates these potentiometer connections.
Installation 5. Installation Note: It is important in all installations that the amplifier mains supply switch is easily accessible. Note: The rack mounting and desk/wall mounting components described and illustrated in Sections 5.1 to 5.3 are not supplied with PowerZone amplifiers but are available to purchase as accessories. Contact your amplifier re-seller for more information. Rack Ear + 2 x M4 x 8 csk 5.
Installation to significant movement. Multiple PowerZone 504 amplifiers can also be mechanically connected using accessory connecting plates. Diagrams 3b and 3c illustrate the use of rack mount rear support hardware and connecting plates. Connection Plate + 4 x M3 x 6 csk Diagram 3c 2 x PowerZone 504 with connection plate. 5.3 Free-standing If not to be installed in an equipment rack, PowerZone amplifiers can be placed free-standing on a flat surface. Adhesive rubber feet are supplied for this purpose.
Installation 5.4 PowerZone 1004 Mounting Note: The rear support components described and illustrated in Sections 5.4 are not supplied with PowerZone amplifiers but are available to purchase as accessories. Contact your amplifier re-seller for more information. The PowerZone 1004 amplifier is shipped with rack mount ‘ears’ attached as illustrated in Diagram 5a and is primarily intended to be installed in an equipment rack.
Connections 6. Connections 6.2 Input Connections Note: The micro USB socket located on amplifier rear panels is present for service and diagnostic purposes only. PowerZone amplifier inputs are of balanced, line level format with a input sensitivity of +4dBu (full output voltage swing/ sensitivity) in all modes. Input signal levels up to +24dBu can be handled without input clipping. The amplifier rear panel connection sockets are illustrated in Diagrams 6a and 6b.
Connections 6.4 Speaker Cable Gauge Speaker connection cable gauge should be chosen appropriately to reflect the type of installation. The adjacent tables specify the appropriate cable gauge for less than 0.5dB cable loss with different installation types and cable lengths. 6.5 GPIO Connections If any GPIO functionality is required, cables will need to be connected to the supplied GPIO connector. Connecting cables to the supplied female GPIO connector is illustrated in Diagrams 7d.

Operation 7. Operation Once all connections have been made and DIP switches set, the amplifier can be connected to mains power. After a short delay, and if an input signal above -55dB is present on any input, the front panel standby indicator will illuminate green to indicate normal amplifier operation.
