18、 . . . . . . . . . .12 RadioFans.CN 收音机爱 好者资料库 This page intentionally left blank. The Bogen Gold Seal Series amplifiers were designed with the sound contractor in mind. They provide unparalleled flexibility and versatility, without the need for add-on modules. Unlike other typical amplifier lines,
19、the professional sound contractor need not purchase a higher-powered amplifier just to get more extensive features or flexibility. Each of the Gold Seal Series amplifier models incorporate the exact same set of features from 35 watts up to 500 watt models. In addition to its extensive input flexibil
20、ity, the Gold Seal Series amplifiers offer a combination of features not found in any other commercial amplifier.

36、or disable phantom power to each of the 4 dedicated microphone inputs (MIC 5 and MIC 6 phantom power selection see page 5). Input Connections 4 MIC 1-4 (Rear Panel; #21 and #22) MIC 1 through 4 utilize female XLR-type microphone connectors. A slide switch located above each XLR connector is used to
37、supply phantom power for condenser microphones. MIC 5/TEL (Rear Panel; #8 and #9) The MIC 5/TEL input is designed to accept input from a microphone or from a telephone line. A slide switch is provided to select MIC 5 or TEL input. To connect a microphone, place the MIC 5/TEL switch in the MIC positi
38、on. Use two conductor shielded cable and connect the cable shield to the center GND terminal. To use the TEL input, place the MIC 5/TEL switch in the TEL position and connect the 600-ohm telephone paging source (dry signal only - no DC voltage) to the MIC 5/TEL screw terminals. See page 5 for Phanto
39、m Power for MIC 5. MIC 6/AUX 1 (Rear Panel; #6, #7, #20) The MIC 6/AUX 1 input is designed to accept input from a microphone using terminal strip connections or from a high level auxiliary source such as a tuner or CD player using the AUX 1 RCA jack. A slide switch is used to select input type. Conn
40、ect a microphone to the screw terminals labeled MIC 6 (works only when AUX 1/MIC 6 switch is in the MIC 6 position). Use two conductor shielded cable and connect the cable shield to the center GND terminal. Connect an auxiliary input source to the AUX 1 RCA jack (only works when the AUX 1/MIC 6 swit
41、ch is in the AUX1 position.) See page 5 for Phantom Power for MIC 6. AUX 2 (Rear Panel; #19) The AUX 2 input uses an RCA plug and accepts input from a dedicated AUX source. Installation Note Keep input leads away from the output leads and AC power cables. Unless the driving source provides a low-imp
42、edance output, keep the input lead under ten feet in length. Make all connections to the unit with the POWER switch in the OFF position 1 GND 2 + 3 Input Connections 5 Remote Volume Control (Rear Panel; #10) If remote volume control is desired, connect the Bogen accessory GSRVC Remote Volume Control
43、 to the screw terminals marked REMOTE MSTR. Wire length can be up to 1000 feet using 22-gauge wire. Connections are not polarity sensitive. Precedence Connections (Rear Panel; #11) Precedence connections allow any combination of inputs to be completely muted with a contact closure. Closing a contact
44、 across any of the prece- dence terminals and the PREC COM 1 terminal will mute that input. A customer-supplied normally-open SPST switch, push-to-talk switch, microphone switch, relay or telephone system contact can be used to provide the closure. Note: Activating the precedence control for AUX inp
45、uts completely mutes the input signal. The VAR MUTE control has no effect when muting inputs using precedence control. Phantom Power for MIC 5 #1) Speaker systems are connected directly to the speaker output terminals on the rear panel. Connect one speaker lead to the COM terminal and the other to t
46、he terminal corresponding to the impedance of the speaker system. Select only one of the output types. For ground-referenced output operation (unbalanced systems), install a shorting clip between COM and GND. For special applications that require floating outputs (balanced systems), do not install a
47、 shorting clip between COM and GND. Note: If GND/COM shorting clip is not installed, the WMT1A and “TO PWR AMP” outputs will not operate. WMT1A (Rear Panel; #2) This RCA output jack, when used with a Bogen WMT1A Line-Matching Transformer accessory provides a 600-ohm output to feed a remote amplifier
48、 or a telephone line. Refer to the instructions provided with the WMT1A accessory for connection information. Note: Shorting clip between GND/COM on the speaker output terminals strip must be installed to use this feature. To Power Amp (Rear Panel; #3) The Gold Seal Series amplifier may be used to d
49、rive an external power am- plifier (can only be used with unbalanced high-impedance inputs). Note: Shorting clip between GND/COM on the speaker output terminal strip must be installed to use this feature. Pre-Out/Power In Jacks (Rear Panel; #12, #13, #14) These jacks permit the insertion of signal processing equipment into the signal path betwe
