(1) Connect the Basic System Note: It’s strongly recommended that all connections be made with the power off. Place the Components • Place the teacher’s instrument in an optimal teaching position (e.g. at the front of the classroom). • Place student instruments in rows facing the teacher’s instrument (row configuration is optional). Be sure to allow extra space behind each student station so that the teacher can move easily from station to station. • Place the RCS-848 Hub in a central location. • Place the Conference Controller on or near the teacher’s instrument. • Optional— Place the external audio playback/recording device(s) (e.g. CD player/recorder, hard disk recorder, computer, etc.) on or near the teacher’s instrument. • Optional—Place the external audio monitor(s) to the side of the teacher’s instrument facing the student instruments. • Optional—Place the video monitor(s) on a pedestal or wall mount near the teachers station (facing the student instruments). An SVGA projector may also be used, but be sure to allow sufficient, unobstructed space between the projector and screen. Connect the Cables • Connect all devices to AC power strips as described under “Electrical Requirements.” Note: It’s strongly recommended that all connections be made with the power off. • Place one RCS-1 interface box on each instrument (including the teacher’s instrument). • Use the supplied 1/4" to 1/4" TRS cables to connect the headphone output of each instrument to the [Instrument Left/Stereo] input on each RCS-1 interface box. • Optional—Numerically label each student instrument so that the teacher can easily identify student stations from the optimal teaching position. • Connect the RCS-848 Conference Controller to the [Remote] connector on the RCS-848 Hub using a supplied RJ-45 (8-conductor telephone-type) cable. • Connect the teacher’s RCS-1 interface box to the [Teacher] connector on the RCS-848 Hub using a supplied RJ-45 (8-conductor telephone-type) cable. 10 Chapter 1: Installation Guide • Connect each student RCS-1 interface box to the corresponding numbered connectors on the RCS-848 Hub using supplied RJ-45 (8-conductor telephone-type) cables. • Optional—Connect the audio outputs on the external audio playback device(s) to the [Aux. In] / [CD In] jacks on the RCS-848 Hub using optional cables. • Optional—Connect the [Rec. Out] jacks on the RCS-848 Hub to the audio input(s) on the external audio recording device using optional cables. • Optional—Connect the [Mon. Out] jacks on the RCS-848 Hub to the audio inputs on the external monitoring system using optional cables. Test the Basic System When all conference system components are placed and the cables are connected, test each component using the following procedure. Power Up Note: It’s strongly recommended that you power up the conference components in the following order. • Student instruments • Teacher’s instruments • External audio playback/recording device(s) • Visual monitors • Computer(s) • RCS-848 Hub • External monitoring (speaker) system Test the Teacher’s Station • Simultaneously press the [All] and [STUDENT MUTE] buttons on the RCS-848 conference controller to “clear all” settings. • Set the output level on the teacher’s instrument to somewhere between 50%-100%—this provides the best signal-to-noise audio response. • Set the [TEACHER MIC] and [TEACHER HEADPHONE] sliders on the RCS-848 conference controller to somewhere between 50%-100%. • Put on the teacher’s headset and play a few notes on the teacher’s instrument. You should hear what you’re playing. If you don’t hear anything, check the teacher’s instrument and teacher’s headset connections. • Press the [TEACHER MIC] button on the RCS-848 conference controller and talk into the teacher’s microphone. You should hear yourself. If you don’t hear anything, check the teacher’s headset connections. 11 Chapter 1: Installation Guide Test the Student Stations • Simultaneously press the [All] and [STUDENT MUTE] buttons on the RCS-848 conference controller to “clear all” settings. • Press the [All] button on the RCS-848 conference controller. • Play a few notes on the teacher’s instrument while an assistant listens at Student Station #1. The assistant should hear what you’re playing. If the assistant doesn’t hear anything, check the RCS-1 interface box-to-RCS-848 Hub [1] connections. • Have the assistant adjust the output level on Student Instrument #1 to somewhere between 50%-100%—this provides the best signal-to-noise audio response). • Have the assistant play a few notes on Student Instrument #1. The assistant should hear what he or she’s playing. If the assistant doesn’t hear anything, check the student instrument-to-RCS-1 interface box connection(s). • Have the assistant say something. You and the assistant should hear what he or she is saying. • If needed, make RCS-1 interface box level adjustments with the [Inst. Level L/R] adjusters on the side of th...
