GENERAL DESCRIPTION: The PM series Mixer Amplifiers, PM-30(30W), PM-60(60W), PM -100(100W), are designed for years of trouble-free use in diverse commercial and industrial applications. They pro- vide paging, announcement, intercommunication and background music systems in in- dustrial plants, offices, churches, hotels, department stores, shopping centers, night clubs, restaurants, convention halls, auditoriums, and stadiums. Their main feature is the ability to withstand overload and open or short-circuiting of the output. The PM series requires no complicated protective circuit to withstand accidents or mismatched output con- nections that may occur during the installation or use of a PA system. The amplifier is protected by a circuit breaker when other abnormal electrical conditions occur. Four microphone inputs are provided for High and low Impedance microphones. Four auxiliary (Tape/Tuner, Phono, Phone, Aux) inputs are provided for signal sources such as FM-Tuner, cassette player, remote-microphone, ceramic or crystal phonograph cartridge, and telephone system. Speaker outputs are complete with 4, 8, 16 ohms (usable 4-16 ohms) and 25V or 70V line connections. All the inputs and outputs are secured with screw terminals. Terminals have been covered for protection against electric-shock. | There are four microphone volume controls, four auxiliary volume controls, a master volume control, bass tone control, treble tone control, and power on/off switch, plus an overload LED pilot lamp are provided. Also, a VU meter has been added for visual monitoring.

Mic-2 Input Terminals INSTALLATION: Unpacking: Upon receiving shipment, please inspect for any damage incurred in transit. If damage is found, please notify your Aiphone distributor. Connecting of Components: An FM tuner, Cassette player, remote microphone, chime and other high level signal sources may be connected to high impedance inputs with a single-conductor low capacity shielded cable. The high impedance microphone with a single-conductor shielded cable of 30” to 60° (10-20m) length can be plugged into the Mic. 1 input. Make certain that all input cables are kept away from speaker cables, power cables and power transformers. Speaker cables must be also kept away from power cables. Grounding the Unit The chassis of the unit must be grounded by using GND (=) terminal located on rear side and connected to an earth ground (eg: cold water pipe). | If additional equipment is connected to the amplifier, make sure that these chassis are individually secured to the same ground. - OPERATIONS: Over Load If the external load exceeds the rated power, a safety circuit will respond and protect this unit immediately. (Even if the load is short-circuited), the protective circuit will be activated by loading 1.5 times over the rated power. If the “OVER LOAD” lamp is illuminating or the circuit breaker on rear panel is turned off, please turn off the power and check the cutput circuit. When a correct circuit has been secured, push circuit breaker back to original position and turn power on. Make sure overload lamp is off, otherwise re-check the otuput circuit. Volume Control Setting | | For the average input signals, the master gain control should be set to the middle. In relation to the levels of inputs, it is recommended that the gains or losses be equally divided between individual controls and the master control. Tone-Controls The separate tone controls provide boost and attenuation of bass and treble response. The flat position is obtained when the knobs are set to mechanical center. — 4 — Turn BASS control knob and TREBLE control knob respectively, clockwise to raise tone level by approximate +10dB, turn counter-clockwise to lower tone level by approximate -10dB. 7. INPUT CONNECTION: Microphones Four microphone inputs are provided. They may be used with balanced or unbalanced high impedance (50K ohm) or Low impedance (600 ohm) microphone. A microphone with an unbalanced connection cable of 30’ to 60’ (10-20m.) may be used, but it depends on the microphone and its characteristic.. Mic-1, Mic-2, Mic-3, and Mic-4 Mic-1 is unbalanced-High impedance and is provided with a double pole phone jack located on the front panel. | Mic-2 is balanced Low impedance, and Mic-3, and 4 are unbalanced-Low Impedance, and are located on the rear panel. Balanced Low Impedance Microphone Connect to the double conductor shielded cable. Os Balanced microphone Unbalanced High Impedance Microphone May also be connected to the single conductor shielded cable of unbalanced high impedance microphone. a Single pole phone plug to Mic 2 input Terminal ff i= unbalanced Microphone to Mic 1 Phone Jack ‘Unbalanced Low Impedance Mircrophone to Mic 3 or Mic 4 | Phone Jack unbalanced Microphone Phonograph | Connect ceramic or crystal cartridge pick-up to Phono input (55mV 500Kohm).

Auxiliary (AUX, PHONO, TAPE PLAYER, TUNER) An FM tuner or tape palyer may be connected to the TAPE/TUNER input.

OUTPUT CONNECTIONS: Speaker Output The amplifier may be used in conjunction with a speaker rated at 4, 8, 16 ohms or with balanced output 25 Volt or 70 Volt constant-voltage speaker systems. Low Impedance Speaker Output: 4, 8, 16 ohm | | The 4, 8, 16 ohms terminal is provided for the connection of a few large-output speakers. This applies when constant-voltage speaker system is unnecessary or in case the distance between the amplifier and the speakers is short enough (less than 200ft). It is requested that the total speaker load impedance the correctly matched to the output impedance of the amplifier for most efficient transfer of power. Be sure that total impedance of speaker is above 4, 8 and 16 ohms. However, do not raise amplifier output power over the endurable input power of speaker, otherwise the speaker would be damaged. 25V and 70 Volts Speaker Ouput When it is desired to operate the speaker from a distance of over 200’ from the ampli- fier, it is recommended that line matching transformers be installed on the speaker units to prevent excessive line losses. This method of load matching known as the constant voltage distribution system eliminates the calculation of load impedance and series-parallel speaker arrangements. In this method; all speakers are connected in parallel. These constsant voltage outputs are most convenient for distribution of power when a number of speakers are installed. Each speaker must have 25 volt or 70 volt line transformer with a tap that gives the power desired for that speaker. The total number of power settings for all speakers should be equal to the amplifier power rating or less. - 6 — Wiring instruction is indicated as follows: COM 40 89 162 Ф|Ф1Ф|Ф| 49 + GND OV 25V 70V 25V 1 PPD Y a Vv Output Meter | The swing of the output meter indicates output level.
