CONNECTING EXTERNAL EQUIPMENT 7. 1 INTRODUCTION This chapter describes the procedure for installing and configuring external equipment for use with the Voicecrafter. The Voicecrafter supports the use of an external microphone mixer and/or an external power amplifier. An external microphone mixer is required when providing more than two microphones. An external power amplifier is required when providing distributed loudspeaker systems. Click the Train button (ACOUSTIC screen) and click on F3 when prompted, to begin a Configuration Train cycle. Once acceptable training responses have been achieved (see paragraph 4. 3), store the resulting configuration by clicking on the Store button (ACOUSTIC Screen) followed by the desired memory location (F1~F5). CONNECTING EXTERNAL EQUIPMENT 7. 3 EXTERNAL AMPLIFIER WITHOUT LOCAL REINFORCEMENT The Voicecrafter has a line level audio output that is capable of driving external power amplifiers. This line level output is provided on a rear panel RCA jack labeled LINE OUT. 7. 3. 1 INSTALLATION Connect LINE OUT to the input of the external amplifier. Connect the external amplifier to the loudspeakers that are to be used. When more than one loudspeaker is to be used, they should be wired in phase (loudspeakers wired out of phase will cause acoustic dead zones in the conference room). For distributed loudspeaker systems (25V, 70V, 100V), the external amplifier will require proper interface for the constant voltage system which is to be installed. **The Voicecrafter internal amplifier is not capable of interfacing to distributed speaker systems.

If Voicecrafter should attempt to train, wait for Train cycle to complete before continuing. Click on AutoAdapt (ACOUSTIC screen) and use F3 to select FULLY DISABLED. Then activate the Voicecrafter white noise generator by clicking on the Noise button (ACOUSTIC screen). [. . . ] Enable ­ To turn on. Acoustic Coupling - Loudspeaker signal which is picked up by the microphone(s). Acoustically Dead - A conference room environment with surfaces which reflect very little sound. Such environments contain surfaces such as sound absorbing panels, curtains, carpeting, etc. 28 VOICECRAFTERTM EQ Setting - Refers to the switch, available on many conference microphones, which boosts and/or cuts select frequencies. Far End - A remote or distant site, located at the opposite end of a conference transmission line. [. . . ]
