• Aflgjafi: Tengdu við ampeingöngu við tilgreindan aflgjafatage. Ensure the power cord is not damaged or pinched.
• Loftræsting: Do not block any ventilation openings. Install in accordance with the manufacturer's instructions, ensuring adequate airflow around the unit.
• Vatn og raki: Ekki láta þetta tæki verða fyrir rigningu eða raka. Ekki setja hluti sem eru fylltir með vökva, eins og blómavösur, ofan á tækið.
• Hiti: Ekki setja upp nálægt neinum hitagjöfum eins og ofnum, hitatöflum, ofnum eða öðrum tækjum (þ. amplyftara) sem framleiða hita.
• Þjónusta: Reynið ekki að gera við þessa vöru sjálfur. Látið hæft þjónustufólk sjá um alla þjónustu. Þjónusta er nauðsynleg þegar tækið hefur skemmst á einhvern hátt, svo sem ef rafmagnssnúra eða kló er skemmd, vökvi hefur hellst niður eða hlutir hafa dottið ofan í það, tækið hefur rignt eða raka, virkar ekki eðlilega eða hefur dottið.
• Þrif: Taktu þessa vöru úr sambandi við innstungu áður en þú þrífur hana. Ekki nota fljótandi hreinsiefni eða úðabrúsa. Notaðu auglýsinguamp klút til að þrífa.

4. Uppsetning og tengingar

Áður en þú tengir nokkra íhluti skaltu ganga úr skugga um að amplifier is powered off and unplugged from the mains supply. Refer to the diagram below for a visual guide to the front panel controls.

4.1 Inntakstengingar

• Microphone/Auxiliary Inputs: The amplifier accepts inputs from two sound sources. Connect your microphones or auxiliary devices (e.g., CD player, media player) to the designated input jacks on the rear panel. Ensure proper cable types (e.g., XLR for microphones, RCA for auxiliary) are used.
• Telephone Line Input: Connect a 600 ohm telephone line to the dedicated input. This input has its own level control for adjusting the volume of telephone audio.

4.2 Úttakstengingar

• Útgangur hátalara: Connect your speakers to the appropriate output terminals on the rear panel. The amplifier supports 4, 8, and 16 ohm speaker loads. Ensure the impedance of your speakers matches the selected output terminals.
• Constant Voltage Úttak: For distributed audio systems, connect speakers to the 70 volt or 25 volt line outputs as required. Ensure all speakers in a constant voltage system are compatible with the chosen voltage.
• Music on Hold Output: Connect your music on hold system to this output. It provides both a 600 ohm line output and a one watt 8 ohm output, each with separate level control.

4.3 Rafmagnstenging

Once all audio connections are made, connect the amplifier's power cord to a suitable AC power outlet. Ensure the power switch on the front panel is in the OFF position before plugging in.

5. Notkunarleiðbeiningar

This section details the functions of the front panel controls and key features of the PBM-30 amplíflegri.

5.1 Stjórnborð á framhlið

• POWER rofi: This is the main power switch for the amplifier. Press to turn the unit ON or OFF. The indicator light will illuminate when the unit is powered on.
• MIC 1 Control: Adjusts the volume level for the microphone connected to Input 1.
• MIC 2/AUX Control: Adjusts the volume level for the microphone connected to Input 2 or the auxiliary audio source.
• BASS stjórn: Adjusts the low-frequency (bass) response of the audio output. Turn clockwise to increase bass, counter-clockwise to decrease.
• Diskantstýring: Adjusts the high-frequency (treble) response of the audio output. Turn clockwise to increase treble, counter-clockwise to decrease.

5.2 Auto Mute Function

The auto-mute function automatically mutes background music or other audio when a signal is detected on a priority input (e.g., a microphone input for announcements). This ensures that announcements are clear and audible without interference from other audio sources. The sensitivity and priority of the auto-mute function may be configured via internal jumpers or rear panel controls, if available (refer to detailed wiring diagrams for specific setup).

5.3 Manual Muting Contacts

The amplifier includes manual muting contacts, allowing for external control of the muting function. These contacts can be wired to an external switch or control system to manually mute audio output when activated. Consult the wiring diagram in the full technical manual for proper connection of these contacts.

5.4 Music on Hold (MOH) Output

The dedicated Music on Hold output allows you to feed background music to a telephone system's MOH input. Use the separate level control to adjust the volume of the music being sent to the telephone system.

6. Viðhald

Proper maintenance ensures the longevity and optimal performance of your Speco PBM-30 amplíflegri.

• Þrif: Þurrkið reglulega ytra byrði amplifier with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and then dry thoroughly. Do not use harsh chemicals, abrasive cleaners, or solvents.
