Tips on Using Monarchy Audio Amplifiers
- Never short output terminals.
It might cause the output MOSFETS to blow
and this is NOT covered by the warranty.
- 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.
- Rule of Thump:
- Turn the amp ON last.
- Turn the amp OFF first. This avoids the on/off thumps from the
preceding stage.
- 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.
- 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.
SE160 Instructions
- Please see On/Off operation per separate page.
- This version has a 12.6V tube installed(12AT7).
We strongly recommend against pulling the tube out to
try something else.
Please put off any attempt to substitute tubes until several months later.
Let the amp mellow out and enjoy the music in the mean time.
Only the direct equivalent of 12AT7, such as ECC82, should be used.
- There is an output protection relay.
The relay cuts out the “thump” at turn on, then settles to connect the output
to the speaker.
But as the tube warms up, aberrations may cause the relay to cut out again.
This is a normal function of the protection circuit.
The amp needs at least a 15 minute warm up to sound normal.
- Because tubes age quickly in constant use, we strongly recommend
turning the amp OFF while not in use. This saves energy too.
- Good Ventilation is important.
