Expansion Host Features

 Designed with a standard 2U chassis, made of high-end oxidized blackened aluminum alloy with a

frosted panel, revealing a premium look and high-class quality.

 Work with the amplifier host PAVA9500, and can be combined with the expansion amplifier PAVA9425E

for emergency broadcasting and background music broadcasting.

 With a built-in local customized alarm or voice signal player, and 4MB storage space (in MP3 format, the

storage length of the program source is determined by the sampling rate and storage space) to store up

to 10 different program sources, which can be changed via the MICRO USB interface. Trigger settings for

input dry contacts can be completed via a PC.

 With 2 built-in 500W digital power amplifiers for automatic switching and backup as well as BGM

broadcasting.

 With AB line speaker output for 8 zones, with independent switch and volume control for each zone,

with master volume and treble/bass adjustment, with an output of 500W for each zone and a total

power of no more than 500W for 8 zones.

 With 8-zone on/off function, including on/off buttons for independent zones and all zones.

 Support 6 external inputs, including 2 balanced microphone inputs, 4 balanced line inputs for fire audio

input and background music broadcasting; and 1 line output for external expansion or recording

backup.

 Featuring dual RJ45 network ports and CAN bus transmission, the host and expansion amplifier are

cascaded hand-in-hand or looped. If the host is connected to a single expansion amplifier, it can support

a maximum transmission distance of 600 meters; if connected to expansion amplifiers in a centralized

manner, it can support up to 19 PAVA9500E expansion amplifiers, with a total of 160 zones, or up to 30

PAVA9425E expansion amplifiers, with a total of 128 zones.

 Work with the host to realize automatic playback and timing functions, enabling timed fixed-point and

fixed-area track playback and unattended operation.

 Work with the host to realize remote microphone paging and zone/group broadcasting.

 With 8 trigger inputs (with dry contact and level optional), 8 dry contact trigger outputs, and 8 24V

override outputs.

 Support remote computer detection and control, audio priority settings, operating records review, and

impedance detection parameters settings.

 Support speaker line detection (grounded, open circuit, short circuit).

 Support AC power supply and DC24V power supply, which can be identified and switched automatically,

with AC power supply as the main power supply normally.

 With AC and DC power connection detection and warning functions.

 With 5-digit DIP address settings.

 Support system fault detection, emergency output and emergency reset input.

 With multi-function display for device working status: working/fault/normal.

 With monitoring function, it can work with the host for dry contact programming output.

 Support simultaneous output of dual audio, support remote paging for any single or multiple zones

while broadcasting background music, without interrupting background music broadcasting of other

zones. In this mode, the emergency broadcast remains the highest priority and will be broadcast to all

zones forcibly, followed by the paging broadcast, and the background music channel will act as a backup

to the emergency broadcast channel.

 Priority level: Bus Emergency Audio (output from the host CAN data audio bus to each expansion

amplifier, play Host EMC MIC EVAC or ALERT depending on the host priority) > Fire Alarm Dry Contact

Trigger > Bus BGM Audio (output from the host CAN data audio bus to each expansion amplifier) = 1-6

External Inputs.
