This Ashly Pema 8250.70 powered digital signal processor consists of 8 inputs and 8 power amplifier outputs with the ability to assign any input to any output. Each input channel includes a summed stereo (RCA, +11dB maximum) and mic/line gain stage (3-pin Euroblock, +21dB maximum) capable of 0, +20dB, +40dB, and +60dB of gain with +15V phantom power when selected. Summed stereo input impedance is 3.16k Ohms unbalanced and mic/line input impedance is 4.8k Ohms active balanced.

Channel one includes a transformer-isolated TEL-PBX select. Each input and output has individual mute capability. Each input and output has six processing blocks configurable for Dynamics (ambient noise compensation, compressor/limiter, auto-leveler, ducker, gate), Gain (including Group VCA and remote gain), Equalization (FIR filters, 31-band graphic, parametric x 10, feedback suppressor), Crossover, Delay, Metering, and Signal Generator (sine wave, pink noise, white noise).

The routing stage allows the user to assign an input to any or a combination of outputs and separately adjust how much signal level goes to each output (matrix mixer). The matrix mixer also has selectable gain-sharing automatic mixing capability. Each input stage has an additional preamp output (post DSP) on the back panel (3-pin Euroblock). Eight powered outputs deliver 250W @ 70V (7.62mm Euroblock), and channel pairs can be bridged for 500W @ 70V. Frequency response is ±1dB 20Hz to 20kHz. Signal-to-Noise is greater than 102dB, 20Hz – 20kHz unweighted. LED indicators show the signal level (-18, -12, -6), clip/mute, bridge, over temperature and over current conditions. Output levels can be adjusted by the front panel volume controls when enabled. Full programming and control of the unit can be from the rear panel by an RJ-45 jack connected to a 10/100BASE-T Ethernet LAN connected to a PC running Ashly’s Protea NE Software. Thirty internal presets (scenes) are standard and four scenes are accessible via contact closure.

The powered digital processor has CobraNet and Dante factory options and are able to transmit up to eight Dante channels. A back panel contact closure will place the unit in "Standby" mode reducing power consumption when in idle. Five password usernames and eight levels of security are available. A temperature dependent speed-controlled axial fan maintains the correct operating temperature. The unit weighs 20 lbs net and mounts in a standard 19" rack using 2 spaces (3.5" high).
