The B800 features:

• 5 frame sizes: 24, 32, 40, 48 and 56 module-widths are available.

• 8 Mono Groups (or 4 Stereo Groups).

• 2 Stereo Master Outputs.

• 6 Mono Auxes & 2 Stereo Auxes.

• Stereo AFL/PFL

• 4 VCA Groups

Power Supply

The B800 uses the CPS275 Power Supply.

Important Notice.

The console has two earth posts on the rear c onnec to r pane l. They are loc ate d ne ar to the power supply connectors. The un-insulated metal post is the chassis ground, and the insulated post is the system ground. The co nsole is supplied with these two posts linked together. It is essential that the console is ope rated with these two earths linked. They may, however, be linked at a different point in the installation: for example, a technical earth in the installation site . In this case the wire link between the two posts must be removed.

The meterbridge has a number of connectors as shown below.

The MONITOR/COMMS D-type connector routes signals to the Monitor Se lector PCB ( see the Meterbridge connector list on the previous page fo r pin details).

The ANCILLARY METERS D-type connector carries the Groups and Auxes into the meterbridge. The actual connections used will depend on the number of a ncillary meters which are fitted. The connections are:

1 Gnd 14 Gnd 2 Group8 15 Group7 3 Group6 16 Group5 4 Group4 17 Group3 5 Group2 18 Group1 6 Not Used 19 Not Used 7 Not Used 20 Not Used 8 Aux1 21 Aux2 9 Aux3 22 Aux4 10 Aux5 23 Aux6 11 Aux7L 24 Aux7R 12 Aux8L 25 Aux8R 13 Not Used

The EXTERNAL INPUTS XLRs are also routed to the Monitor Selector PCB. The inputs here may be monitored on the Meters which are associated with the Monitor Selector PCB.

There are also 2 additional XLRs. The first of this is commonly used to connect the T/B Mic feed from the meterbridge to the T/Binput in the console, via the XLR on the flying lead. The second XLR is for future expansion.

There are two 90-way EDAC’s associated with the master section. Viewed from the rear of the console, EDAC1is to the right of EDAC2. These 2 EDAC’s have the functions described on the next pages. Other EDACs on the console may be for stereo group and stereo channel outputs, and wiring information for these will be specified to each console and is therefore supplied separately. These EDAC receptacles, often known as fe male, have pins which are surrounded by a protruding plastic moulding. The photograph below shows the pin labelling (as viewed from the outside of the console).

J10 & J11 If the Q Speaker Outputs are not being used, link J10 pins 1 to 2, and

link J11 pins 1 to 2. In this configuration, a sum of the Cue Left and Right Signals are routed to the Cue Speaker on the Overbridge. This feed is muted by using the Overpress facility (if it is fitted).

If the Q Speaker Outputs are being used, link J10 pin1 to J11 pin1, and link J10 pin 2 to J11 pin 2. In this configuration the sum of the Cue Left and Cue Right signals is never routed to the Cue Speaker on the Overbridge. The individual Cue Left and Cue Right signals are routed to their respective Cue Speaker Outputs, but these are muted by using the Overpress facility (if it is fitted). Alternatively if only pins J10 pin2 and J11 pin 2 are linked then the Overpress facility will not mute the Cue L & R signals to the Cue Speaker Outputs.

The DESK ’A’ bank of switches, on the Monitor Module, allows you to sele ct 1 of 6 internal signals as the internal monitor source. The 6 are selected via th e scramble card (SC3556) in the console . The a ppropriate section of this PCB’s silk scree n is reproduced below. The six signals may be chosen from the following list:

•

Group 1 to Group 8 ( Group 1 toGroup 4 L + R for Sterero Group )

•

The Main Stereo Mixes of the ST1 and the ST2 Modules

•

The Mono Mixes of the ST1 and the ST2 Modules

•

Aux1 to Aux8.

There is also a spare left and spare right feed which may be used to monitor any suitable point in the console.

Fitting Links

Suitably sized hair-pin links may be soldered into the appropriate thro ugh-plated holes. T ake care to select the correct side when connecting a stereo pair. For example, if you wanted to assign Source 1 to Aux 6 then you would fit links L20 and L46. If you then wanted to assign Source 2 to Aux 7 (which is a stereo pair) then you would fit links L73 and L100.

The factory default setting is:

Left Right

Source 1 ST1 L ST1 R Source 2 ST2 L ST2 R Source 3 GP1 / ( GP1L ) GP2 / ( GP1R ) Source 4 GP3 / ( GP2L ) GP4 / ( GP2R ) Source 5 GP5 / ( GP3L ) GP6 / ( GP3R ) Source 6 GP7 / ( GP4L ) GP8 / ( GP4R )
