POWER CONNECTION

Connect the input interconnect and speaker cables before you insert the power cable into the

receptacle at the left (facing the back) rear of the chassis on one M-2500, and on the right on the

other (See Figure 6). The M-2500s use a standard 15 amp three prong male IEC connection for AC

input. You need to use power cords with a female 15 amp, three prong IEC connector at one end. The

Allnic ZL-3000 and ZL-5000 power cables will make an excellent match.

The M-2500s you have purchased are set internally for either AC 110/120 volt – 60 HZ, or 220/230 volt –

50 HZ operation. There is no way to change this to another AC setting without return of the M-2500s to

the factory for re-wiring, at the owner's cost, including transport both directions.

INITIAL POWER-ON

Once you have your M-2500s in place and all connections have been made to your source(s) and

preamplifier, you are ready to turn on the power for your M-2500s. Before you power up the M-2500s,

though, be sure you have:

removed ALL the cushion materials (cardboard) from inside the tube chimneys.

•

leave the "O" rings on the small tubes; some prefer the sound with the O rings on.)

• selected the input connection that you want to use, single ended (RCA) or balanced (XLR), on the

switch on the back of the chassis and have the interconnect firmly attached.

• turned on your source(s) and your preamplifier, and turned the preamplifier's volume control down to

zero or otherwise muted its output

• securely and correctly fastened the speaker cables and ensured that they are also connected properly

to the speakers

• checked that all tubes are snug in their sockets

Turn on the M-2500s by depressing the power switch button located (facing the front of the unit) on the

right side-panel (on one chassis and on the left side on the other) to the "on" position (See Figures 4 and

5). The "on" position is with the top of the button switch depressed. Of course, the off position is the

reverse. After about a thirty to forty (30 - 40) second delay (the soft start), the M-2500s will be powered

on. After warm up and application of full plate voltage, not all tubes may bias at the same rate. Allow one

or two minutes for all the tubes to reach full operating specification.

OPERATION

When the power is on, the current meter on the front of the chassis will illuminate (See Figure ). From this

point on, operation is straight-forward. When you are finished listening, turn off your M-2500

monoblocks first; then, turn off your preamplifier and sources.
