Spracht Voice Center cp-2010 - Manual (Page 15)

General
Installation of External Microphones (Optional)
The Voice Center Conference Phone has 3 built-in microphones for
complete 360° coverage in areas up to 10 x 15 ft (3 x 4.5 m).
The Voice Center Conference Phone has RJ-22 input jacks for two external
microphones to extend coverage in larger areas and to allow for irregular
layouts. Voice Center External Microphones (Spracht catalog no. EM-101)
are sold separately from the Voice Center Conference Phone. An EM-101
External Microphone comes with a 70 inch (1.8 m) cable with RJ-22
connector (same connector as used for telephone handsets).
To install an external microphone:
1. Plug the RJ-22 microphone connector into one of the two microphone
connectors on the underside of the Conference Phone; the micro-
phone connectors are labeled “EXTERNAL MIC.”
2. Place the external microphone at least 18 inches (0.5 m) from the
Conference Phone and (if present) another external microphone. The
diagrams below show some common arrangements for external
microphones with the Conference Phone.
Connection of an External Recording Device (Optional)
The Voice Center Conference Phone provides an RCA jack for connection
of an external recording device (such as a tape recorder). This
provides a convenient means to record a teleconference held with
the Conference Phone, and to obtain the highest quality recording
possible.
The connection for the external recording device is an audio RCA
coaxial connector located on the underside of the Conference Phone.
