10. 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 (page 19).
11. 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 20). 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.
12. 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 "Paging Input (if used)" in
this manual (page 20). 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.
13. 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 21).
14. 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 21) for additional
details. Line coupling transformers utilized
between an earlier ("Phase 1") Audio Tower and
the Call Director are not required and they should
be removed in Enhanced Audio Enclosure
applications.
15. Completion
❏ Continue with the following power-up procedure.
POWER-UP PROCEDURE
❏ The following C3 Maestro power-up procedure is
recommended:
1. If the Personal Computer and/or monitor are
equipped with a voltage selector switch, verify the
switches are positioned correctly. The power
supply within the Enhanced Audio Enclosure will
operate from any ac voltage from approximately
100 Vac to 240 Vac; no voltage selection switch
exits on it.
2. On the three (3) units, verify each power switch is
in the off position.
3. Connect the PC, video display monitor and the
Enhanced Audio Enclosure to a 115 or 230 Vac
source. Normally, 1½ duplex ac receptacles are
required for the three (3) power cords. Refer to the
PC and monitor documentation as necessary.
Extension cords should not be used with the C3
Maestro console system.
4. Verify all equipment is properly grounded.
5. Power-up the Enhanced Audio Enclosure. The
on/off power switch lights when ac power is
applied and the switch is in the on position.
