1272X /1275X SPEAKER CONNECTIONS SETUP SUGGESTIONS
The 1/4" jacks are wired in parallel
allowing any one of the jacks to be used
as an input and the other as an output.
This allows "daisy chaining" of multiple
loudspeakers, eliminating the need for several long, cumbersome runs of
speaker cable. The connections are as follows:
Polarity | Phone Jack |
Positive (+) | Tip |
Negative | Sleeve |
Connect the amplifier to the loudspeaker with a minimum 16 gauge wire when a length of no more than 100 feet is used. When multiple speakers are “daisy chained” together or where longer cable runs are encountered, use a larger gauge wire. Although no harm or hazard will result, using too small a gauge of wire may cause the sound quality and level to degrade.
CARPET COVERING CARE
1272X /1275X cabinets are covered in a tough, black indoor/outdoor synthetic carpet for long life and lasting good looks. To clean the carpet covering, simply vacuum away any smudges or dirt. For stubborn stains, use a light
soapy solution or carpet shampoo with a brush. Avoid spilling liquids on the input panel, grille and speakers.
The placement of any speaker can affect its sound. Thus, there are several considerations to review when placing your 1272X /1275X monitor.
CAUTION! When operating with large amplifiers (greater than 150 watts at 4 ohms) always set the level control between the 3 o’clock and 5 o’clock positions. Failure to do so may lead to overheating and damage the level control.
1)When using stage monitor systems, the reduction of feedback is probably the most important criteria. The best way to reduce feedback is to use a CARDIOID pattern microphone with it’s rear aimed at the loudspeaker. Remember: Do not cover the side or top slots of the microphone with your hands as this could cause feedback.
2)Select a 30 or 60 degree angle based upon the working distance that you will need. A 30 degree angle is preferable for performers who require a greater working distance from the monitor so that movement about the stage is on axis with the monitor. A 60 degree angle is preferable for performers who have a shorter working distance and who do not move around the stage.
3)When larger movements are expected, 1272X /1275X monitors may be used as side fill monitors so that wide horizontal coverage can be provided. If used in the side fill position, it may be advantageous to elevate the speaker from the floor to keep it aimed at the performer’s ear level.
The side fill position at about 10 to 15 feet from the performer is particularly useful for drummers and keyboard players. This allows program monitoring while keeping the monitor clear of your equipment. In the side fill position, the drummer’s / keyboardist’s vocal microphone can be positioned to the side allowing the rear of the microphone to face the front of the monitor minimizing feedback.
