IP peaker or IP enabled legacy paging y tem .
The rotary control knob ha three po ition (mu ic, microphone and off). The 8301 will
automatically detect the control knob po ition to tart multica t for either the microphone
or mu ic input a elected, or top multica t in the off tate.
The mu ic input u e a 3.5mm tereo input jack compatible with AppleTM iPodTM and other
ource . Left and right tereo channel are combined into a balanced mono ignal
compatible with public addre infra tructure. The mu ic volume i adju ted by both the
Audio Input Volume etting in the web interface of the 8301 and manual adju tment of the
ource level.
The microphone input u e an XLR connector compatible with dynamic microphone uch
a the Sennhei erTM E835 and imilar microphone that do not require phantom power.

Wiring Connections
Two pair of wire connect the 1205 Audio Interface to the Algo 8301. One pair i for
balanced audio and one pair i for communicating the rotary witch po ition.
Connect the “8301 SW INPUT” witch terminal of the 1205 Audio Interface to the “RELAY
IN” of the 8301. Connect the “8301 LINE IN” audio terminal of the 1205 Audio Interface to
the “LINE IN” of the 8301. Neither pair i polarity en itive.
Important Safety Information
DRY INDOOR LOCATION ONLY
The 1205 Audio Interface i intended for indoor dry location only.
CAT5 or CAT6 connection wiring to an IEEE 802.3at PoE+ or 802.3af
compliant network PoE switch must not leave the building perimeter without
adequate lightning protection. No wiring connected to the 1205 or 8301 may
leave the building perimeter without adequate lightning protection.

ESD PROTECTION
Electrostatic discharge to the 1205 Audio Interface faceplate or audio
connectors will be conducted to the 8301 Paging Adapter which is
normally isolated from electrical ground per the IEEE 802 3af
standard
To protect against a charge build up in the Algo 8301 which might
otherwise cause a reset or damage to the device or network switch
port, Algo 8301s manufactured with Rls 13 (May 2019) or later contain
circuitry designed to dissipate accumulated charge For this feature
to work properly the network switch must be designed to dissipate
accumulated charge as well For example, the Cisco Catalyst 2960S-
24PS-L at +/- 20kV ESD testing yielded good results without
grounding
Network switches with external power supplies (even if chassis
grounded) should not be used with the 8301 and 1205 Call Switch
without protective grounding This can be achieved by connecting a
24 AWG or larger wire between either conductor of the “SW INPUT”
or “RELAY IN” wires to Earth ground This wire is to bleed away any
accumulated charge from ESD hits that would otherwise be
dissipated by the network switch
