SPEAKER TERMINALS

The 2000 25

anniversary is equipped with high-

quality speaker terminals for each channel. These

terminals are located on the left side of the rear

panel of the A-2000 25

the chassis rear), with the right speaker

connections closest to the left side of the chassis.

The terminals for the live connections, marked

positive "+" are on the top, and the return

connections labeled negative "-", underneath.

Between the left and right pairs of terminals is a

switch that provides for either 8 or 4 ohm

impedance, as your speakers may require. The

upper position of the switch is for 8 ohm operation;

the lower for 4 ohm operation. 8 and 16 ohm

terminals are available by special order. The

terminals accept bare wire (not recommended) and

spade and banana type connectors. Please refer to

Figure 4.

POWER CONNECTION

Connect the input interconnect and speaker

cables before you insert the power cable into

the receptacle in the centre (facing the back)

rear of the chassis. The A-2000 25

uses a standard three prong male IEC

connection for AC input. You need to use a

power cord with a female three prong IEC

connector at one end. Please refer to Figure 4.

The A-2000 25

anniversary you have purchased

is set internally for AC 220 volt – 60 HZ operation.

There is no way to change this to another AC

setting without return of the unit to the factory

for re-wiring, at the owner's cost, including

transport both directions.

INITIAL POWER-ON

Once you have your A-2000 25

place and all connections have been made to your

source(s) and preamplifier, you are ready to turn

on the power for your A-2000 25

anniversary chassis (facing

anniversary.

Before you power up the A-2000 25

though, be sure you have:

•

removed ALL the cushion materials (cardboard

around and "O" rings on tubes) from inside the

tube chimneys

•

selected the input connection that you want to

use, single ended (RCA) or balanced (XLR); and

if you are using the XLR connectors, set the

switch beside them to the appropriate pin

configuration.

•

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 power tubes are snug in their

sockets

Turn on the A-2000 25

the power switch button located at the right of the

front panel (facing the front of the unit) to the "on"

position (See Figure 5). The "on" position is with 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 A-2000

anniversary will be powered on.

OPERATION

When the power is on, the current meters on the

top plate of the chassis will illuminate. From this

point on, operation is straight-forward. When you

are finished listening, turn off your A-2000 25

anniversary first; then, turn off your preamplifier

and sources.

If the A-2000 25

triode mode at turn-off, they will produce a sound

through the speakers as the amplifier's relays turn

off. Though this sound is harmless to speakers,

some users may prefer not to hear it. To avoid the

sound, simply switch the A-2000 25

to pentode mode prior to turning them off (see the

"On-the-Fly Triode/Pentode Switching section

below).
