Amplifier not plugged in. AC outlet dead. Power switch off. Circuit breaker tripped. Power Switch Indicator is ON. No signal from source. Volume turned down. Speakers not connected correctly. Link jumper not set correctly (pg. 5). DISTORTED SOUND Power Switch Indicator is ON. Volume Controls are turned up. Unit is extremely hot. Little volume. Partial short on the output. Check speakers and wires. Power Switch Indicator is ON. Volume up. Good volume. Signal from source is already distorted. Input signal too large for input type (reduce signal level applied to input). Poor speaker connections. Transformer output load on wrong tap. Bass control boosted too much. Output too great for speakers, reduce level. POOR LOW FREQ. RESPONSE (NO BASS) Power Switch Indicator is ON. Volume controls are in normal, operational position. Speakers wired out of phase. Bass control set to cut side Note:Transformer-coupled speakers have less bass response. NOISE/HUM Power Switch Indicator is ON. Volume controls are in normal, operational position. Poor electrical connections at input. Shields of cables not connected. Input cable routed near AC cables, power transformer, or other EMI radiating devices. Electrically noisy devices operating on the same AC circuit. Poor equipment grounding. - Ensure that all ACsafety grounds are connected. - Make sure that all components in audio chain are tied to the same ground.

Technical Specifications The public address amplifier shall be a Bogen Model _, or approved equivalent, with a full power rating of _watts. (Specify: C35/35 watts, C60/60 watts or C100/100 watts.) The fre- quency response (transformer) shall be 70 Hz to 16 kHz 2 dB,with less than 1% distortion.Input sen- sitivity shall be 600V for low-impedance balanced microphones, 85mV for auxiliary inputs, and 75mV for TEL input. Hum and noise shall be 55 dB below rated output for the MIC inputs and 70 dB below rated output for the AUX and TEL inputs. The amplifier shall provide one dedicated low-imped- ance balanced microphone input,one dedicated Hi-Z auxiliary input, and one dedicated telephone line input, as well as a fourth input that is switch selec- table to be either a microphone or auxiliary input. The microphone inputs shall be equipped with filters to protect against RF interference. Independent vol- ume controls for each input as well as TREBLE con- trol (11 dB 10 kHz) and BASS control (11 dB 100 Hz) shall be incorporated. A precedence cir- cuit shall mute the AUX 2 input when a customer- supplied external switch is actuated. The amplifier shall include a TEL volume control to adjust the telephone paging level and a VOX volume control to adjust the TEL input signal level trigger point for automatic muting of the AUX inputs. The amplifier shall provide output impedances of 4- (direct), 8-, and 16-ohm speaker systems as well as for 25V and 70V constant voltage systems. Two high- impedance outputs shall be provided to drive a tape recorder or booster amplifier and,when used with an accessory transformer (WMT1A),to feed a 600-ohm telephone line. The amplifier shall contain a resettable thermostat in the power transformer to protect against heat build- up and short-circuited or overloaded connections. Provision shall be included to mount the amplifier in 19-inch equipment racks,using an optional rack panel kit (Model RPK50).Dimensions shall be 14-1/2 W x 3-3/4 H x 11 D. Shipping weight shall be _lb. (Insert 16 lb.for C35,18 lb.for C60 or 20 lb. for C100.)
