Application Diagrams
A: Typical Stereo Application
This diagram depicts a simple setup, using the DX8 in a stereo application. A microphone is connected to the MIC input on channel 1 for paging purposes, and several program sources are connected to the LINE inputs on channels 3 through 8.
B: Typical Two-Zone Application
This configuration demonstrates how the DX8 might be used in a restaurant/bar application. A paging mic is connected to the MIC input on channel 1. Notice the priority enable switch near the paging mic, which causes the other inputs to either turn off or reduce their volume levels, depending on how the
Zone A uses a 70V distribution system for broad coverage using multiple speakers throughout the restaurant area.
Zone B uses a stereo power amplifier configured for mono operation to power two or four speakers in the bar area. Each zone has a pair of remote controls, allowing access to predefined functions such as level control and program source selection in each zone.
A 24V DC power supply is connected to the POWER INPUT connector on the DX8, for backup operation in case of an AC power failure.
C: Two DX8s In Church Application
This illustrates using two DX8s to meet the many requirements in this church application. The primary DX8 is used to connect the various microphones located at the pulpit, lecturn, and choir loft. Two additional microphones from the Fellowship Hall are connected to MIC inputs 5 and 6. A CD player is connected to LINE inputs 7 and 8 for playback of prerecorded music for soloists when required.
A pair of remote controls is located at the pulpit, primarily for selecting presets for various events such as Sunday morning service, Monday evening Bible study, and Saturday afternoon weddings. Another pair of remotes is located in the Fellowship Hall to control the level for the microphones (assigned to a Fader B Control Group) in the Fellowship Hall, and to choose whether the Sanctuary mics are heard in the Fellowship Hall and whether the Fellowship Hall mics are heard in the Sanctuary.
A cassette deck is connected to the RECORD output jacks for recording the service.
The A OUTPUT is connected to a stereo power amplifier configured for mono operation that drives a pair of loudspeakers that cover the sanctuary.
The B OUTPUT is connected to an additional power amplifier configured for mono operation that provides power for a pair of speakers in the Fellowship Hall.
The secondary DX8 is used to connect the microphones and instruments for the band. The A and B OUTPUTS are connected to the BUS A and B LINE inputs on the primary DX8, where the signal is mixed with the program sources connected to the primary DX8.
A digital multitrack recorder is connected to the DIRECT OUTPUTS on the secondary DX8 for tracking the vocals and instruments for later mixdown to
A laptop is connected to the front panel COMM PORT on the secondary DX8, using a standard
D:Board Room Application With
connected to a DX8. The podium mic is connected to channel 1, and has a priority enable switch near it connected to a logic input for the moderator to use to mute or duck the other microphones, if required. Two zones are covered using 70V distribution.
Zone B can be partitioned off, and has a second DX8 for selecting either the board room source (connected to BUS B LINE input), or the microphones in Zone B (for a separate meeting going on simultaneously).
Each zone has a pair of remote controls for configuring the system as needed.
