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. Both an external mixer and an external amplifier are required when sound reinforcement of the local microphones is desired. 7. 2 EXTERNAL MIXER WITHOUT LOCAL REINFORCEMENT An external microphone mixer is required when more than two microphones are to be used. Mic 2 of the Voicecrafter is capable of accepting a signal from an external microphone mixer. (If sound reinforcement of local mics is desired, refer to paragraph 7. 4. ) 7. 2. 1 INSTALLATION The Mic 2 input must be configured for a line level input. Click on Input Mode under Mic 2 (ACOUSTIC screen). Use F3 to select Line Input (Balanced or Un-balanced depending on mixer used). 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.

Use the following procedure to calibrate the amplifier: 1. Apply power to the Voicecrafter and the external amplifier. 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.
