Before You Turn On the Amplifier

  1. Ensure it is the right AC voltage for your country.
  2. Allow good air circulation around the amplifier. This unit dissipates 200 Watts of energy even when idling. It should never be placed inside a cabinet unless forced air cooling is provided. We recommend this amp be placed near your speaker so that the two amps are a distance apart from one another. If the two amps are placed in close proximity, make sure there is good airflow around them. The two amps should never be placed on top of one another.
  3. Placing the amp close to the speaker has the added advantage of saving on expensive speaker cables, and allowing the amp to drive the speaker better. Use short cables.
  4. Ensure the pre-amp is turned on FIRST and the Co-axial or balanced cable is connected to the amp. If you turn the preamp on after the SE-100 is switched on, the preamp will generate a large pulse that could be detrimental to your speakers. There is
    also a good chance it would wipe out the output MOSFETS . This is not covered by the warranty and the user must pay a charge for factory replacements. Never connect the Co-axial and the balanced cable to the amp at the same time.

To Operate

  1. Turn the switch on. If the light on the switch does not light up, check the AC fuse.
  2. Although the amp will operate properly immediately after turn-on, it would take about 30 minutes for it to reach optimum working condition. At that point the heatsinks should heat up to 40-50 degrees Celsius. Do not allow the amp to operate continuously above 60 degrees. The amp may eventually fail.
  3. For every 10 degrees’ rise in operating temperature, the chance of failure doubles. Transistor failure as a result of inadequate ventilation is not covered by the warranty.
  4. Do not turn unit back on immediately after it is turned off. Wait one minute for the high capacitance capacitors inside to discharge. Other than the AC fuse at the rear panel, there are three more fuses inside the unit for the positive and negative rails and the speaker output. If ever any of these fuses blew, check the cause before replacing them. The rating of the fuse is marked on the metal end. Replace with the same type only. Please see ‘CAUTION."

Tips on Using Monarchy Audio Amplifiers

  1. Never short output terminals. It might cause the output MOSFETS to blow and this is NOT covered by the warranty.
  2. Do NOT turn the amp off and on in quick sequence. It takes a few minutes for the remnant voltage inside the amp to discharge.
  3. Rule of Thump:
    • Turn the amp ON last.
    • Turn the amp OFF first. This avoids the on/off thumps from the preceding stage.
  4. If possible, use an AC noise filter and/or Surge Suppressor at the AC input. All Monarchy Audio amps have very wide bandwidth and noise could pass into the amp and superimposed on the audio signal.
  5. Make sure there is no DC component from the preamp’s output. Some models of the Monarchy Amps are DC coupled and DC could be amplified into the speakers, causing the coils to overheat.

Caution

  1. There are 3 fuses under the top plate of the SE-100: 1) The two labeled “High Voltage” carry + or – 50 volts DC.
    2) the fuse rating is 8 amp fast blow, and3) the unlabeled one is the speaker fuse. It should be 5 Amp fast blow
  2. If the amplifier is grossly overdriven beyond its power rating,
    any one or two or all of these fuses will blow.
  3. They should be replaced with the same rating (8 amps)
  4. However, if the amplifier is used extensively on 4 Ohm or even
    lower loads, 10 Amp fuses should be used.
  5. If only one of these fuses has blown, there would be no sound coming out to the speakers. There could even be a DC offset voltage
    at the Speaker Output Terminals. If this happens, disconnect the speaker from the terminals immediately. Check the source of
    the problem (e.g., overdriven, the amp has been turned off and on in quick sequence, shorted Speaker outputs etc.)
  6. Allowing the DC offset into the speaker might eventually deform the voice coil, or even burn out the woofer. MONARCHY AUDIO
    is not responsible for this negligence by the user.
  7. For those users handy with a Multimeter, the DC offset should be checked After the fuses have been replaced. There should be less than 20 mV(0.02 volt) At the Speaker Terminals. This small offset (either of plus or minus polarity) will subsequently settle to near zero. Any value under 30 mV is perfectly acceptable.
  8. Please remove the AC cord from the amplifier before replacing fuses.
  9. A Note on the Output MOSFETS:
    • These are matched at the factory (4 pcs per bank , one Positive, one
      Negative).
    • If ever these have to be replaced, both banks have to be
      sent back to the factory.

SE-100 fuses

  1. Please note the following fuse ratings:
    • 1: AC input on the rear panel
      For 117Volt AC, this can be a 5 to 6.3 Amp fuse.
    • For 220-240Volt AC, a 3-4 Amp fuse will do.
  2. There are 3 fuses on the main circuit board, marked as F1, F2, and F3.
    • F1 and F2 are +/- DC rail fuses. These should be 6.3 A to 8 Amp
    • F3 is the speaker Output fuse, normally a 5Amp.
    • If a very low impedance speaker load is used(2 or 3 Ohm), this
      can be changed to a 6.3 to 8 amp fuse.
  3. All fuses are Fast Blow type.
  4. The AC line must be removed before changing any fuse.
