MA-150, for use in connecting more than two speakers. See the section titled SPEAKER HOOKUP for detailed instructions for hookup of multiple speakers. Do not connect a tape recorder or any other sound equipment to the speaker jacks of the MA-150. Doing so could cause overheating of the amplifier, and possibly damage it. - Page 10 To Change Selected Voltage: Four AC voltages can be used with the MA-150: 100V, 120V, 230V or 240V. To change between voltages, pull the voltage selector card straight out of the housing using the indicator pin.

Depending upon the size, shape, and acoustic characteristics of a hall, getting comfortable sound coverage may require one, two or more speakers. It is important to locate them properly, for best coverage of all areas of the floor. For information on locating speakers in the hall, see the heading SPEAKER LOCATION in the section titled GETTING THE MOST FROM YOUR HILTON. - Page 14 MORE THAN TWO SPEAKERS DO NOT CONNECT MORE THAN TWO 8 OHM SPEAKERS OR MORE THAN ONE 4 OHM SPEAKER TO THE MA-150 WITHOUT CAREFULLY READING THE INSTRUCTIONS WHICH FOLLOW, AND THE DIAGRAMS CONTAINED IN THIS MANUAL. HOW TO DETERMINE NET IMPEDANCE...
- Page 15 MA-150 produces a 4-ohm load. If you should connect four 8 ohm speaker in parallel or two 4 ohm speakers directly to the MA-150, this parallel connection produces a 2 ohm load, which at high drive levels will produce excessive energy which is dissipated in the form of heat and cause the MA-150 to shut down.
- Page 16 coil may become jammed at one end of its excursion, making the speaker inoperative. 3. A short circuit may occur in the voice coil, ruining the speaker and possibly causing damage to your amplifier. NEVER CONNECT TWO AMPLIFIERS TO THE SAME SPEAKER OR SPEAKERS! GETTING THE MOST FROM YOUR HILTON, AND AVOIDING DAMAGE TO IT MICROPHONE TECHNIQUE Always work close to your microphone -- never let it get more than an inch from your lips.

Some recorders have inputs of such low impedance that if they are connected in a speaker circuit they produce the same effect as an improper speaker hookup: overheating and possible damage to the MA-150. MONAURAL RECORDINGS... -
Page 18: Connecting To An External Amplifier
Use the SIGNAL OUT jacks on the Rear Panel to make Monaural recordings with full program (the same as is going to the speaker). The HIGH jack is an adjustable line level signal and would be connected to the Line or Auxiliary input of your recorder. -
Page 19: Routine Inspection And Maintenance
ROUTINE INSPECTION AND MAINTENANCE Routine cleaning and inspection of your sound system, microphone and cords will help in preventing trouble and maintain the appearance and performance of your Hilton.

microphone cord assembly. CHECKING SPEAKERS If a speaker has been dropped or handled roughly, it may develop a misalignment of the voice coil resulting in a "dragging cone". To check for this, hook up the speaker to the amplifier and play some music. Turn the volume off, and set the bass at maximum and the treble at minimum. - Page 21 For example, if a microphone should stop working, the source of the trouble might be in the microphone itself, in the cord, or in the input of the amplifier. A few simple tests before notifying us would be of great value in isolating the source of the problem and correcting it quickly for you.
- Page 22 SPEAKER DEAD OR INTERMITTENT: Recheck all speaker connections. Switch cords and speakers to see if the fault is in the speaker or in the cord. AMPLIFIER GOES DEAD: Check to see if the power switch is on. If it is, check the AC hookup and source of power. Take out and check the fuse.
