2. Amplier Overview
The PowerZone 252 amplier is a half width 1U rack format,
two channel audio power amplier that can drive both
conventional low impedance (4Ω to 16Ω - Low-Z) loudspeaker
loads and constant voltage (70V/100V - Hi-Z) transformer
coupled loudspeaker loads. Each output channel can be
independently congured to drive either Low-Z or Hi-Z loads.
The PowerZone 252 amplier is capable of a maximum
simultaneous output of 125 Watts per channel into both Low-Z
or 70V/100V Hi-Z loads but also incorporates automatic
power sharing technology that enables 250 Watts to be shared
proportionately across the output channels.
The PowerZone 504 amplier is a half width 1U rack format,
four channel audio power amplier that can drive both
conventional low impedance (4Ω to 16Ω - Low-Z) loudspeaker
loads and constant voltage (70V/100V - Hi-Z) transformer
coupled loudspeaker loads. Each output channel can be
independently congured to drive either Low-Z or Hi-Z
loads. The PowerZone 504 amplier is capable of a maximum
continuous simultaneous output of 125 Watts per channel
into both Low-Z or Hi-Z loads but also incorporates automatic
power sharing technology that enables 250 Watts to be shared
proportionately across each pair of output channels.
The PowerZone 1004 amplier is a 1U rack format, four
channel audio power amplier that can drive both conventional
low impedance (4Ω to 16Ω, - Low-Z) loudspeaker loads and
constant voltage (70V/100V - Hi-Z) transformer coupled
loudspeaker loads. Each output channel can be independently
congured to drive either Low-Z or Hi-Z loads. The PowerZone
1004 amplier is capable of a maximum output of 250 Watts
per channel into both Low-Z or Hi-Z loads.
Channel gain control knobs and status indicators are located
on the front panel. Signal input and output connections are
accomplished via ‘Euro Block’ connectors and operational
congurations are set up through a DIP switch module located
on the amplier rear panel. A rear panel GPIO (General
Purpose In/Out) connector is also provided that enables some
amplier functions to be controlled or monitored remotely.
The ampliers have no mains power switch and are operational
as soon as mains power is connected. The ampliers should be
connected to switched mains sockets.
PowerZone amplier dimensions and features are illustrated in
Diagrams 1a, 1b and 1c. The ampliers are primarily intended
for installation in an equipment rack but can also be under-desk
or wall mounted, or used free standing. They are fan-cooled
and must be installed such that ventilation apertures are not
obstructed.
