    BALANCE and LEVEL are input controls. These four controls are fed by the 3.5mm stereo jacks marked AUX 1 and AUX 2 on the Front Edge of the MA-220. The BALANCE adjusts the signal level between A & B of a two track or stereo signal. The LEVEL control sets the volume feeding the MUSIC section.

    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-220. Doing so could cause overheating of the amplifier, and possibly damage it.

    HUM OR BUZZ WHEN USING YOUR LAPTOP? — SEE PAGE 12 FOR THE EASY FIX. First let's go over some general rules for playing back through the MA-220. Later in this section we will get into specifics on connecting particular types of devices to the MA-220.

  • Page 9: Setup And Operation

    Keep in mind that you are using the INPUT LEVEL controls and output control on the signal source to set the proper signal level going into the MA-220, not as volume controls. Once these are set, then use the MUSIC control to adjust the volume.
  • Page 10 IN SERIES-PARALLEL--the net impedance of each parallel group, multiplied by the number of parallel groups connected in series. The minimum impedance load for the MA-220 amplifier is 4 ohms, for best operating results. Hilton Workshopper and Folded Horn speakers are 8 ohms and the LB-1, WA-180, and PS-10 are 4 ohms. Two...

    8 ohm speakers connected direct to the MA-220 produces a 4-ohm load. If you should connect four 8 ohm speaker in parallel or two 4 ohm speakers directly to the MA-220, 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-220 to shut down.

  • Page 12: Making Recordings

    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-220. MONAURAL RECORDINGS Use the SIGNAL OUT jacks on the Rear Panel to make Monaural recordings with full program (the same as is going to the speaker).

    RCA plugs on one end and the other end to match the record jack/s on the recorder is required. The signals level out from the MA-220 is adjustable with the AUX. MUSIC OUT and AUX. VOICE OUT volume controls.

    Check your microphone from time to time -- has its response changed? A mic whose diaphragm is starting to drag will lose its bass response and sound tinny, and there will be an increased susceptibility to feedback. Care of a microphone is fairly simple. Don't drop it, don't blow into it and don't spray or squirt anything into it in an attempt to clean it.
