7. Microphones & Headsets

Connect existing mics and headset jack boxes to the

Enhanced Audio Enclosure per section

“INTERCONNECTING THE EQUIPMENT”,

subsection “ENHANCED AUDIO ENCLOSURE” in

this manual (begins on page 23). No wiring changes are

necessary.

8. Footswitches

Audio Tower "FOOTSWITCH 1" should now be used

as an operator footswitch. Connect it to Enhanced

Audio Enclosure's "OPER FT. SW." connector. This

footswitch keys all non-supervisory mics; see the

NOTE on page 24 for microphone priority information.

Also see the subsection entitled “Footswitches (if

used)” in this manual (page 24) for additional details.

Audio Tower "FOOTSWITCH 2" should now be used

as a supervisor footswitch. Connect it to Enhanced

Audio Enclosure's "SUPER FT. SW." connector. This

footswitch keys only the supervisor's headset.

9. Speakers

Speakers used with the Audio Tower are un-amplified

units; therefore, they cannot be used with the Enhanced

Audio Enclosure. Speakers used with the Enhanced Audio

Enclosure are amplified units and each includes a volume

control. The Volume Controller Box is not employed in

Enhanced Audio Enclosure applications.

Existing (old) speakers and the Volume Controller Box

were disconnected in step 1. Install and cable the new

Speakers Assemblies (desktop or rack-mount) to the

Enhanced Audio Enclosure in accordance with the

subsection entitled “Speakers (if used)” in this manual

(page25).

10. Recorder Outputs

If recorder outputs were utilized in the Audio Tower

installation, rewire these connections to the Enhanced

Audio Enclosure in accordance with the subsection

entitled “Recorder Outputs (if used)” in this manual

(page 25). Audio Tower recorder connections utilized a

large removable terminal block; Enhanced Audio

Enclosure recorder connections utilize a smaller

removable terminal block - the terminal block must be

changed. However, note the pin-out sequence is

identical. Audio Tower I/O Board J1 terminal 1 (top

terminal of "UNSELECT RECORDER" and

"SELECT RECORDER" terminal block) corresponds

to Enhanced Audio Enclosure "RECORDER" terminal

1. Likewise, Audio Tower I/O Board J1 terminal 4

(bottom terminal) corresponds to Enhanced Audio

Enclosure "RECORDER" terminal 4.

11. Paging Inputs

If a pager was utilized with the Audio Tower

installation, rewire these connections to the Enhanced

Audio Enclosure in accordance with the subsection

entitled “External Paging Encoder Input (if used)” in

this manual (page 25). Audio Tower pager connections

utilized a large removable terminal block; Enhanced

Audio Enclosure pager connections utilize a smaller

removable terminal block - the terminal block must be

changed. However, note the pin-out sequence is

identical. Audio Tower I/O Board J2 terminal 1 (top

terminal of "PAGE INPUT" and "PAGE PTT"

terminal block) corresponds to Enhanced Audio

Enclosure "PAGER" terminal 1. Likewise, Audio

Tower I/O Board J2 terminal 4 (bottom terminal)

corresponds to Enhanced Audio Enclosure "PAGER"

terminal 4.

12. Relay Outputs

If any relay outputs were utilized in the Audio Tower

installation, rewire these connections to the Enhanced

Audio Enclosure in accordance with the subsection

entitled “Relay Outputs (if used)” in this manual (page

26).

13. Call Director

If the Audio Tower was connected to a Call Director,

connect the male DB-9 connector on the cable from the

Call Director (disconnected in step 1 from Audio

Tower's I/O Board "CALL DIRECTOR" DB-9) to the

Enhanced Audio Enclosure's female DB-9 "CALL DIR"

connector. See the subsection entitled “Call Director

(if equipped)” in this manual (page 26) for additional

details. Line coupling transformers utilized between an

earlier ("Phase 1") Audio Tower and the Call Director
