Module Installation - Output Module Bays Only

1. Turn off all power to the unit.

2. Make all necessary jumper selections.

3. Position module in front of any desired output module bay opening*, making
sure that the module is right-side up.

4. Slide module on to card guide rails. Make sure that both the top and bottom
guides are engaged.

5. Push the module in to the bay until the faceplate contacts the unit’s chassis.

6. Use the two screws included to secure the module to the unit.

* This module is designed to be used in output module bays only.

Module Installation in M-Class (Input Module Bays)

In the case of an M-Class application, the module can be modified to fit into an M-Class
input module bay by removing the break-away tab.

WARNING:
Turn off power to unit and make all jumper
selections before installing module in unit.

Gain (Input)

Provides control over the level of
input signal.

Level (Output)

Provides control over the level of
output signal.

RJ11 Connection

This connector contains the out­put signal and a set of normally
open relay contacts. It acts similar
to telephone systems’ page ports
and facilitates interfacing to paging
systems with override capabilities
(PCM2000, ZPM3).

Signal Output

Transformer-balanced, low-imped­ance (8-ohm) line-level output.

Input Signal

Transformer-balanced, line-level
input.

Mute + / Mute -

Provides access to the mute bus
priority system. Allows external
equipment to directly control the
internal mute buses.

Prioritized Relay Output

Provides access to the priority
controlled relay contacts. Can be
jumper configured as normally
open (N.O.) or normally closed
(N.C.).

Jumper Selections

Impedance Selector

This module can be set for two different input impedances.When connecting to a 600-ohm source,
it is desirable to have a 600-ohm matching input impedance.For typical source equipment, use 10k-

ohm setting.

Input Muting

This module’s input can remain continuously active or be muted by other modules.When muting
is enabled, the input is permanently set to the lowest priority level.When disabled, the input will
not respond to any priority signal and will remain active continuously.

Input Bus Assignment

This module can be set to operate so that the input signal can be sent to the main unit’s A bus, B
bus, or both buses. Bus selection pertains to M-Class use only. Power Vector has only one bus. Set
jumpers for both for Power Vector use.

External Mute Priority Level

Determines what priority level the external control will appear like to the system. Selecting
Level 1 will result in the external device becoming the highest priority mute and silencing all lower

priority modules. Likewise for all other lower settings except for priority Level 4, which is not appli­cable since modules with this level cannot send mute signals, but only respond to them.

Relay Priority Level

The relay setting determines what priority level and above will cause the relay to energize. Since
this module’s relay must receive a mute signal from a higher priority module to change states, it is

only possible to use the three lower priority levels (2, 3, 4). Priority Level 1 (highest) is not
applicable.

Output Gating

The output signal can be available continuously or available only when the relay priority level set­ting has been met or exceeded.When set to Active,it provides continuous signal output.When set
to Gate, it provides output based on priority level.

Relay Contacts

This module’s screw terminal relay contacts can be set for normally open (N.O.) or normally
closed (N.C.) operation.

Output Bus Assignment

The output signal can be taken from the module’s A bus, B bus, or the unit’s mix bus. On some
Bogen amplifier products, these buses may be tied together.

Input Wiring

Balanced Connection

Use this wiring when the external equipment supplies a balanced, 3-wire signal.

Connect the shield wire of the external signal to the ground terminal of the external equipment
and to the ground terminal of the RIO1S. If the "+" signal lead can be identified, connect it to the
plus "+" terminal of the RIO1S. If the external equipment polarity cannot be identified, connect

either of the hot leads to the plus "+" terminal. Connect the remaining lead to the minus "-" ter­minal of the RIO1S.

Note: If polarity of the output signal versus the input signal is important, it may be necessary to
reverse input lead connections.

Unbalanced Connection

When the external device provides only an unbalanced connection (signal and ground), the RIO1S
module should be wired with the "-" terminal shorted to ground. The unbalanced signal's shield
wire is connected to the input module’s ground and the signal hot wire is connected to the "+"
terminal. Since unbalanced connections do not provide the same amount of noise immunity that a
balanced connection does, the connection distances should be made as short as possible.

Output Wiring

Balanced Connection

Use this wiring when the external equipment requires a balanced, 3-wire signal.

Connect the shield wire to the ground terminal of the external equipment and to the ground ter­minal of the RIO1S. If the "+" signal lead from the external equipment can be identified, connect it
to the plus "+" terminal of the RIO1S. If the external equipment polarity cannot be identified, con-

nect either of the hot leads to the plus "+" terminal. Connect the remaining lead to the minus "-"
terminal of the RIO1S.

Note: If polarity of the output signal versus the input signal is important, it may be necessary to
reverse input lead connections.

Unbalanced Connection

When the external device provides only an unbalanced connection (signal and ground), the RIO1S
module should be wired with the "-" terminal shorted to ground. The unbalanced signal's shield
wire is connected to the input module’s ground and the signal hot wire is connected to the "+"
terminal. Since unbalanced connections do not provide the same amount of noise immunity that a
balanced connection does, the connection distances should be made as short as possible.

Speaker Output Wiring

8ΩΩOutput

The RIO1S output is capable of driving an 8Ω speaker load.Available power is up to 750mW. When
connecting a speaker, be sure to connect the module’s "+" and "-" to the speakers "+" and "-",
