Amplifier Operation, Hints and Precautions

The SPL-M500 is timed to turn on the speaker outputs after the amplifier's power supply is fully charged up, thus preventing any turn-on noise. Timing of the amplifier's turn-on circuit is usually sufficient to accommodate all the turn-on anomalies from other pieces of gear in a system, making it acceptable to use a single switched power string in a permanent or semi-permanent application.

The SPL-M500 can draw a lot of AC power. Be sure the AC power source for your AC distribution system

has adequate current capability.

In multiple amplifier installations, a sequential turn-on (either manually or via timed relays) is recommended to avoid a sudden major drain on the AC line. Remember, severe reduction of power line voltages affects the amount of power you can get FROM the amplifier. If you need to run long AC extension cords, make sure their conductors are as large as practical (small gauge number). Just as smaller diameter wire causes speaker lines loss, smaller power lines cause loss. The effect of small AC lines is one of the intermittent clipping under severe conditions.

AMPLIFIER OPERATION

1.Turn all equipment OFF.

2.Plug the AC cord into a power source with the correct voltage. In the U.S. and Canada, this is a

120Volt, 60 Hz AC. In other countries, this voltage may vary from 100 to 240 Volts, 50 to 60 Hz AC.

3.Connect the wiring from the signal source to the amplifier's input jack(s).

4.Connect the speaker(s) to the to the output terminals.

5.Adjust the input control level to the minimum (infinity) setting. Set the notch sliders at 0 dB (top).

6.Turn all other equipment ON first, then the SPL- M500 monitor amplifier.

7.Slide the level control slowly up and listen for any feedback problem(s) that may occur.

8.If feedback is encountered, slide the appropriate (LOW, MED or HIGH band) notch depth control down to its lowest position. Next, turn the frequency control knob to pinpoint the location of the problem frequency and cancel it.

9.Slide the control level up until feedback or ringing is heard, then move down until the feedback or ringing stops.

10.Step 8 may need to be performed more than once if several feedback problems occur simultaneously.

HINTS AND PRECAUTIONS

A.To reduce the chance of unwanted noise in your system, keep all patch cables and input signal cables away from all AC power cords, lighting cables and speaker wires. Always use shielded cables for all low level (input and patch point) connections to this unit. Never use shielded cable for speaker wires.

B.When a problem frequency occurs within the overlapping part of the two adjacent frequency bands, the notches can be dialed to have the same center frequency. By doing so, the resulting notch depth provided by the two notches will be deeper than a single notch depth.

C.When two notches are juxtaposed, the result will be a wider notch. This can be helpful in some cases, but may not be desirable in normal operation of the unit as audible frequency loss will occur.

D.When notches are not in use, all the notch sliders must be at the top of their travel. A narrow band is NOT a graphic equalizer. Do NOT put the notch depth sliders in the middle of their travel to boost or cut frequencies. These are CUT ONLY controls.

E.To help prevent overdriving this unit and unwanted distortion, keep the Deltacomp™ switch "in".

F.If you wish to obtain either the optional rear rack ear supports (P/N 040661), please contact your local authorized Fender Pro Audio dealer.
