1. PM-812/0 MODULAR CHASSIS
1.1. DESCRIPTION
The PM-812/0 equipment is a modular frame that can house different card models series C-700
and C-800 (preamplifiers, microphone input cards, fault detection cards, message recording -
playback cards, etc.).
The default configuration consists of one input card (C-810LE), one output card (C-810LS) and a bus with
12 free positions between both two cards.
The cards can occupy one or more positions, depending on the model:
2 positions: C-810PAL, C-810SAL, C-810RP1, C-810RP4...
1 position: C-810LS, C-810LE, C-810PRJ, C-810PPA...
It features a program channel, where the program signals are mixed, and a priority channel, with a
cascading priorities system.
The bus was designed so as to be divided into several sections. In this way, each section (consisting of
one or more slots per card, as required) works as an independent chassis.

1.4. POWER SUPPLY
Use of a + 24 VDC / 3 A power supply is
recommended for the PM-812/0 (see figure 3,
number (1)).
Maximum power consumption is 2.5 A.
The power consumption varies depending on
the model and quantities of each card inserted
in the PM-812/0.
1.5. CHASSIS GROUNDING
For all P.A. systems it is very important that
there is only a single connecting point between
the signal ground and the power grounding
contact.
If the P.A. system consists of several pieces of equipment, they will probably be joined via the chassis
through a ground terminal for connection to the power supply or because they are mounted on a rack
stand.
If the grounds are also linked via the signal circuits, it is advisable to remove the jumper between the
ground and the chassis (see figure 3, number (2)) in all but one of the units.
1.6. PM-812/0 BUS –INTERNAL CONFIGURATION
The default setup of the PM-812/0 consists of an input card (C-810LE), an output card (C-810LS) and a
bus with 12 free card positions.
The cards have cascade priority, so that the card located in the OUT position has the lowest priority
ranking, followed by position 12, position 11, and so on up to position IN, which has the highest priority
ranking.
If the priority of more than one input is activated, only the signal from the card in the highest priority
position reaches the channel output.
In order to make the priority system more versatile, the bus has been designed so that it can be divided
into several sections. Thus, each section (consisting of one or more card slots as required) works as an
independent module.
To do this, the four jumpers between one slot and the next one must be cut, making one part of the bus
independent from the adjacent section. Each of the four jumpers cuts a different signal (priority audio,
program audio, priority between cards and priority bus). See figures 4 and 5.

In this way, an output card can be placed at the end of each section (in the position right before the
position where the jumpers have been disconnected) so that a PM-812/0 with 12 card positions can be
transformed into a PM-812/0 with several groups of cards, each group being independent from the rest,
and with cascade priority inside each group (see example in figure 7).
To install any card in the bus, you must remove the jumper between contacts 8 and 9 in the bus
connector (see figure 6).
The bus jumpers between card positions 4 and 5 (J34, J35, J36 and J37) and between card positions 8
and 9 (J18, J19, J20 and J21) are removed.
Two more output cards (card positions 4 and 8) are installed.
Thus, a PM-812/0 with 12 cards can be turned into three independent PM-812/0.

1.7. CASCADING CONNECTION OF SEVERAL PM-812/0 UNITS
Several PM-812/0 units can be connected in cascade form through the signal input and output cards (see
figure 8).
Any input of the card selected as priority of the first PM-812/0 (A) will have priority over any input of the
following unit –PM-812/0 (B) –and so on, preserving the range of internal priorities of each PM-812/0.

2. C-810LE INPUT CARD
2.1. DESCRIPTION
This card has a program and priority input, with a sensitivity of 0 dB.
The signal applied to these inputs (extension inputs) goes directly through
the bus to the output card (C-810LS).
In combination with the output card, several PM-812/0 modules can be
connected, keeping the cascade priority (see PM-812/0, section 1.7.).
2.2. CONNECTION
The card uses 8-pin RJ45 connectors with metal housing.
2.3. SETUP
Each of the two inputs has a dipswitch that is accessible from the rear plate of the card, which enables
separation of the wire shield from the ground circuit.
To separate the shield from the ground, move the dipswitch to the OFF position (dipswitch number 4 for
the program channel and dipswitch number 1 for the priority channel). See figures 11 and 12.
This is especially useful in installations with noise problems due to ground loops.

Optionally, these inputs can be connected to a balancing transformer (T700) by disconnecting jumpers J1
and J2 for program input, and J3 and J4 for priority input, and connecting the transformers as shown in
figure 13.

3. C-810LS OUTPUT CARD
3.1. DESCRIPCIÓN
This card has one program and one priority output. Both are of a 0 dB
sensitivity and balanced by means of a transformer.
It receives both program and priority channel signals from the bus.
The card allows connection of the oscillator card, the C-810MA microphone
card and the vu-meter card for displaying program and priority levels (see
section 3.6).
In combination with the input card, it allows connection of several
PM-812/0 modules, keeping cascade priority (see PM-812/0, section
1.7).
3.2. PROGRAM CHANNEL OUTPUT
A transformer-balanced output that provides the sum of all the signals
from cards set up as program cards and the program input of the C-810LE
card, with a level of 0 dBu.
3.3. PRIORITY CHANNEL OUTPUT
A transformer-balanced output that provides the signal from the priority activated card, with a
level of 0 dB.
If the priority of more than one input is activated, only the highest-priority input signal reaches the
priority channel output.
3.4. CONNECTION
The card uses 8-pin RJ45 connectors with metal housing.

3.5. SETUP
Each of the two channels (program and priority) has a
dipswitch that is accessible from the rear plate of the
card, which enables separation of the wire shield from
the ground circuit.
To separate the shield from the ground, move the
dipswitch to the OFF position (dipswitch number 4 for
the program channel and dipswitch number 1 for the
priority channel). See figures 16 and 17.
This is especially useful in installations with noise
problems due to ground loops.
3.6. INTERNAL CONNECTIONS
CONECTORES K1 y K2
These are two inputs used to connect the C-810MA/C-710MA microphone card.
K1: K1 is used to mix the microphone signal (0 dB) with the PM-812/0’s other program signals. The
microphone signal is output through the PROGRAM OUTPUT of the C-810LS card.
K2: K2 is used when the user wishes to give absolute priority to the microphone over all other PM-812/0
priority inputs. The microphone signal is output through the PRIORITY OUTPUT of the C-810LS card.
K3 AND K4 CONNECTORS
These connectors are used to connect the oscillator
card.
K3: Oscillator signal input for the priority channel.
The signal uses the card’s PRIORITY OUTPUT.
K4: Oscillator signal input for the program channel.
The signal uses the card’s PROGRAM OUTPUT.
K5 AND K6 CONNECTORS
These outputs are used to connect two external vu-
meters in order to display the program or priority
channel signal level.
K5: Displays the priority channel signal level.
K6: Displays the program channel signal level.
