ASHLY PEMA 8125.70 Network Power Amp 8 x 125W @ 70V Constant Voltage w/ 8x8 Protea DSP

Product Overview

The Ashly PEMA 8125.70 is an 8-channel, 125W-per-channel Protea-Equipped Media Amplifier configured for 70V constant-voltage distributed audio systems, combining an 8x8 matrix mixer, full Protea DSP audio processor, and Class-D amplifier in a single 2U rack-mount unit. With 1000W total output power at 70V and support for Dante and CobraNet network audio option cards, the PEMA 8125.70 serves commercial AV installations where 8 zones of distributed audio are required at moderate power levels, such as retail environments, hospitality facilities, and large commercial facilities with many smaller speaker zones. The integrated 32-bit SHARC DSP with FIR filter capability, gain-sharing automatic microphone mixing, automatic feedback suppression, and real-time event scheduling make this a comprehensive one-box audio system for commercial spaces.

Product Description

The PEMA 8125.70 provides 8 channels of 125W each into 70V constant-voltage speaker systems, making it well suited for installations with a large number of zones where each zone requires moderate amplifier power. The 8-in x 8-out matrix mixer routes any input to any output or combination of outputs, and the full Protea DSP suite on the 32-bit SHARC processor provides FIR filter capability, EQ, dynamics, crossover, delay, metering, and a built-in signal generator for test and noise masking applications. Eight built-in microphone preamps with 15V phantom power support direct microphone connections for paging and conferencing, and the gain-sharing automatic microphone mixer manages multiple open microphone channels to prevent unwanted pickup and maintain consistent levels. The automatic feedback suppressor reduces commissioning time and protects against feedback events during live use, while ambient noise compensation automatically adjusts output levels throughout the day. The real-time clock with event scheduler enables fully automated daily operation without manual intervention. Dual RCA and balanced Euroblock inputs, post-DSP AUX line-level outputs, and a dedicated telephone/PBX input provide comprehensive connectivity for commercial audio source equipment. Both Dante and CobraNet network audio option cards are supported for AoIP integration. Class-D amplifier topology with switching power supply delivers over 80% energy efficiency, and the unit is RoHS certified and made in the United States.

Frequently Asked Questions

When should I choose the PEMA 8125.70 instead of the PEMA 8250.70?

The PEMA 8125.70 provides 125W per channel versus 250W per channel for the PEMA 8250.70. Choose the 8125.70 when the speaker system load per zone requires less power, which is common in installations with many smaller 70V speakers per zone or shorter cable runs.

Does the PEMA 8125.70 include a Dante or CobraNet card?

The base PEMA 8125.70 does not include a network audio option card installed. Dante and CobraNet option cards are available separately for field installation.

Does the PEMA 8125.70 require an external DSP processor?

No. The 32-bit SHARC Protea DSP is fully integrated, providing FIR filtering, EQ, dynamics, crossover, delay, and matrix routing without external DSP hardware.

How many audio zones can the PEMA 8125.70 serve?

The PEMA 8125.70 provides 8 independent amplifier output channels, each capable of driving a separate 70V speaker zone.

Can the PEMA 8125.70 be used for microphone paging?

Yes. Eight built-in mic preamps with 15V phantom power, a gain-sharing automatic mic mixer, and a dedicated telephone/PBX input support paging and announcement applications.
