pema 8125.70 amplifier plus OPDante Option Card. The 8-Channel 1000W Pema Network Power Amplifier from Ashly consists of eight inputs and eight power amplifier outputs with the ability to assign any input to any output. The amplifier features pre-installed OPDante network audio interface card and the Protea DSP Software Suite. When switched into bridged-mono mode, eight powered outputs deliver 75W into an 8 ohm load, 125W into an 4 ohm load, and channel pairs can be bridged for 250W into an 8 ohm load. The power amplifier includes Euroblock input connectors and Euroblock output connectors. Besides remote standby for power up, DC remote level control, and contact closure preset recall, the amplifier also features Ethernet control, level, mute, polarity, temperature, current, and amplifier over current conditions. The front panel indicates power status, standby, protect, power switch On/Off, signal level, bridge, temperature & current levels, and Ethernet communication. A temperature dependent speed-controlled axial fan shall maintain the correct operating temperature. Full programming and control of the unit is from the rear panel RJ-45 jack connected to a 10/100BASE-T Ethernet LAN connected to a PC running the Protea Software. The amplifier mounts in a standard 19” rack using two spaces (3.5” high). The power amplifier has an internal factory-installed Digital Signal Processing (DSP) controlled using the Protea Software Suite (network-enabled). Each amplifier input channel can be configured with pluggable DSP blocks to have its own dynamics control, gain functions, graphic and/or parametric EQ, Hi-pass/Lo-pass filters, time delay, metering, and test signal generator. Hot-plug DSP placement allows you to insert any function into any channel block, even when running live audio. A mixer section with assignable routing allows any input to drive any or all amplifier outputs. The matrix mixer also has selectable gain sharing automatic mixing capability. Outputs have the same DSP functions as inputs, with the addition of a quick and automated crossover setup. Up to 30 presets shall be standard and four presets shall be accessible via contact closure using the Protea Software Suite. 70V constant voltage 8x8 DSP matrix with 8-channel power amplifier OPDante network audio interface FIR Filter capable Eight built-in mic preamp outputs Gain sharing automatic mixing capability Automatic feedback suppression Ambient noise compensation Telephone/PBX input Dual RCA and balanced Euroblock inputs Post DSP Aux line level outputs Stereo summed to mono Event scheduling (RTC) Adjustable HP/LP filters Built-in pink/white noise & sine wave generator Protea DSP software suite Hot-plug DSP placement 15V phantom power for mic inputs Full control using software over 10/100BASE-T Ethernet Automatic DHCP network IP configuration Euroblock connectors for preset recall, DC remote level control, and serial data control External control via standard wall remotes, Ethernet wall remotes, Remote iPad app Level control via variable DC control voltage Stand-by mode activation via contact closure Multi-level security cTUVus, CE, FCC, & RoHS safety/compliance nly available w/ 48 kHz sampling rate (inputs only)Filters: 12In/Out per filter: YesFilter Modes: Float, Restricted, ManualFilter Type: Notch, ParametricFilter Frequency Range: 20 Hz to 20 kHzParametric Filter Level: +15 to -30 dBFilter Bandwidth: 0.016 to 3.995 OctaveDetector Sensitivity: 5 levelsFloat Time: 5 minutes to 24 hours Crossover 2 Way, 3 Way, 4 Way Crossover & High-Pass/Low-Pass FiltersBessel & Butterworth Filters: 12/18/24/48 dB/octLinkwitz-Riley Filter: 12/24/48 dB/octFrequency: Off, 20 Hz to 20 kHz Delay @ 48 kHz Sampling Rate (Input Time, Distance & Temperature)Speaker Delay: 0 to 21 msDelay: 0 to 682 ms@ 96 kHz Sampling Rate (Input Time, Distance & Temperature)Speaker Delay: 0 to 10.6 msDelay: 0 to 341 ms Audio Metering Range: -60 to +20 dBuIncrements: 1 dBPeak Hold Indicator: Yes Signal Generator Pink noise, White noise, Sine waveSignal Level: Off, -50 to +20 dBuSine Wave Frequency: 20 Hz to 12 kHz Mixer MixerGain (0.5 dB increments): Off, -50 to +12 dBMute: Per channelAuto-Mixer: Per channelGlobal Auto-mixer Response: 0.01 to 2 secEnable Ducking at Mixer: YesDucking LED: Per channel if enabledMetering: Level, auto-mixer level Processors Input A/D, Output D/A: 24-bitDSP Processors: 32-bit floating pointSample Rates: 48 and 96 kHzPropagation Delay: 1.42 ms @ 48 kHz & 1.71 ms @ 96 kHz
