Operating Manual - 24.24M Matrix Processor

7) Select desired Baud rate (9600bps or 38,400bps). Note that 38,400bps is only supported by the 24.24M.

8) Go to the <Communications> menu and select <Enable Communications>.

9) The connection should now be established. If it isn't working, make sure the RS-232 switch on the back panel

is out, and make sure the device channel (Channel 1-16) is the same on both the 24.24M and Protea System Software

(see sec. 4.2.)

If other Protea products are used with the 24.24M in the same DATA control loop, check their quick reference

guide or owner's manual to verify all settings and connector types. If the 24.24M is the first unit in a multiple Protea data

chain (including an active remote), press in the RS-232 Mode switch on the back panel, otherwise leave this switch out.

RS-232 will run typically to 1300 feet (at 9600 baud) using high quality cable. Before attempting computer control,

EXACT settings must be made to hardware switches and User Preferences on ALL Protea units involved.

8. GETTING STARTED

8.1 Device Select

Protea System Software encompasses eight different Ashly Audio products, and four

remote control devices. After properly connecting the PC and 24.24M (see section 7.3) select

<24.24M> from the <Devices> pull down menu and then enable <Communications>.

8.2 Metering Options

The 24.24M front panel LEDs offer basic indications of key audio levels and functions. For more detailed meter-

ing, Protea System Software has a separate metering display window showing all inputs and outputs, including input

levels, input autoleveler gain/attenuation, input ducker status, input noise gate status, output levels, and output limiter

gain reduction. Meters can be set to dBu or VU in the <Options> menu. 0 VU = +4dBu (1.228Vrms).

8.3 Preliminary Setup

Before connecting the 24.24M to any live audio components, Ashly recommends creating and saving to the PC a

rough setup of the target application within software. In other words, determine ahead of time what the connections to

each input and output will be, set input preamp gain, configure any signal routing/matrixing, set any output crossover

filters, etc. Define the preliminary setup as much as possible before arriving on site.
