Introduction 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, 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.
Panel Descriptions Front Panel (All Models) 1. MIC 1 to 4 - Individual level controls for dedicated microphone inputs. 2. MIC 5/TEL - Individual level control for MIC 5 or TEL input depending on input mode selected. 3. MIC 6/AUX 1 - Individual level control for MIC 6 or AUX 1 input depending on input mode selected. 4. AUX 2 - Individual level control for dedicated AUX 2 input. 5. Contour - Enables or disables loudness equalization. Affects only AUX 2 and MIC 6/AUX 1 if set in AUX mode. 6.
Panel Descriptions Rear Panel (All Models) 1. Amplifier Output - Terminal strip containing all the Gold Seal speaker outputs. 2. WMT1A - RCA connection for (Bogen model WMT1A) 600-ohm balanced line-matching transformer output. 3. TO PWR AMP - RCA connection provides a low impedance, unbalanced signal level output as a feed to high impedance inputs of other external amplifiers. 4. VAR MUTE - 4 Switch selectable levels of AUX input signal muting during TEL page (works only in the TEL input mode). 5.
Input Connections Installation Note Keep input leads away from the output leads and AC power cables. Unless the driving source provides a low-impedance output, keep the input lead under ten feet in length. Make all connections to the unit with the POWER switch in the OFF position 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 supply phantom power for condenser microphones.
Input Connections WARNING Removal of the amplifier cover exposes internal components and presents an electrical shock hazard. For this reason, do not perform any functions requiring removal of the cover of the amplifier unless you are qualified to do so. Always disconnect AC power from the unit before attempting to remove the cover. Phantom Power for MIC 5 & MIC 6 (Inside Unit) A single internal jumper is provided to supply phantom power to both MIC 5 and MIC 6.
Output Connections Output Terminal Strip (Rear Panel; #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 the terminal corresponding to the impedance of the speaker system. Select only one of the output types. For ALL ground-referenced output operations (unbalanced systems), install a shorting clip (18 AWG solid wire jumper) between COM and GND.
Operation Power Switch (Front Panel; #10) The POWER switch applies power to the unit. Above the switch is an LED light which will illuminate RED when power is on. Individual Volume Controls (Front Panel; #1– #4) Each input is controlled by an individual volume control. Master Volume Control (Front Panel; #8) The overall volume is controlled by the MASTER volume control. Lo-Cut Filter (Rear Panel; #5) The Lo-Cut filter on the rear panel provides low-frequency attenuation on the microphone inputs.
Operation Dual-Function Acoustic Equalizer (Front Panel; #6) The unique dual-function equalizer can be used for acoustic shaping or for feedback control. Note: When the switch is placed in the OUT position, the equalizer is bypassed for a flat response. Acoustic Shaping Mode When the switch is set in the ACOUSTIC EQ position, full range equalization (10 bands on 1 octave centers starting at 62.5 Hz) is provided with a boost/cut of 12 dB.
Operation ALC (Rear Panel; #17) The TEL input features an automatic level control (ALC) which compensates for different voice levels and speaking styles of the individuals using the system. The amplifier is shipped with this control in the OFF (max. counterclockwise) position. To adjust the ALC: 1. Rotate the MIC 5/TEL and MASTER controls to the highest level likely to be used. 2.
Troubleshooting Amplifier will not turn ON. Check the fuse. Replace fuse only with same type and rating. No output on WMT1A and Power Amp Outputs. Make sure that the speaker output GND/COM shorting clip is in place. No telephone output. Make sure that the MIC 5/TEL switch is in the TEL position. Make sure the VOX control is set properly When connecting the telephone Tip & Ring, make sure to use the two outside terminals and not the center terminal (GND). AUX Input will not mute with telephone page.
