Architects Specifi cations
Protea System II 24.24M
The base unit digital matrix processor shall consist of four
inputs and four outputs with a dedicated DSP processor
and A/D, D/A circuitry. All programming shall be accom-
plished using Protea System Software to be supplied with
each device and a PC using a WindowsTM 95, 98, 2000/
XP, ME or NT platform. The installer shall have the abil-
ity expand the processor's input or output configuration
by installing input or output module cards for a total of
twenty-four audio channels with fifteen specific configura-
tions. Each input or output card shall have its own DSP
processor for all digital signal processing blocks and shall
have their own A/D or D/A circuitry. The installer shall
be allowed to expand the base unit's total inputs or out-
puts four channels at a time. The input and output cards
shall be field installable without the need to replace or
reprogram the device's firmware and shall automatically
recognize the base unit's new configuration and display
the new configuration upon power up. The 24.24M Matrix
Processor's firmware shall be supported by flash making
the device capable of field upgrades using Ashly Audio's
Protea System Software.
Each input channel shall include fixed architecture pro-
cessing blocks of Mic Preamp with +48V Phantom Power,
Gain, Delay, fifteen EQ Filters, Gate, Autoleveler and
Ducker. Inputs shall have the option to be configured
to accommodate either mic or line levels. Each output
channel processing block shall include fixed architecture
processing blocks of a Cross Point Mixer, HPF/LPF, Delay,
fifteen EQ Filters, Gain and Limiter. The cross point mixer
in the output section shall allow for routing any input to
any output at any level and mute any input at any output
without affecting the true input configuration. Each input
and output shall have individual mute capability.
The matrix processor shall have a maximum in/out level
of +20dBu. Frequency response shall be ±.25dB 20Hz
to 20kHz. Dynamic Range shall be greater than 110dB
(20-20KHz, unweighted) and SMPTE intermodulation
distortion or THD shall be less than 0.01% at 1KHz,
+20dBu. Input impedance shall be 18K ohms active
servo-balanced. Output impedance shall be active bal-
anced, 112 ohms. Inputs and outputs shall be balanced
type on euroblock connectors. LED indicators shall show
signal level, clip, limit threshold and mute conditions.
Full programming and control of the unit shall be via the
front or rear panel accessible RS-232 serial ports using
Ashly Protea System Software. There shall be 35 factory
presets that may be programmed by the user and stored
in the device's internal memory. The matrix device shall
have separate rear panel euroblock connections provid-
ing remote control for DC voltage level, recall of presets
via momentary or on/off switching and a data-in/data-
out port. These remote ports shall be accessible for con-
trol from either dedicated remote controls or third party
devices. There shall also be a three level security lockout
feature. The digital matrix processor shall weigh 13 lbs
net and mount in a standard 19" rack using 2 spaces
(3.50" high). The power requirement shall be 90-240VAC,
50-60Hz, 40W. The unit shall be the Ashly Audio Protea
System II 24.24M Matrix Processor.
