Basic functions of the PA 2500 R
This chapter describes the basic functions of the
PA 2500 R , which are always available, regardless of the currently
selected source.
Switching on
The PA 2500 R can be switched on and off using the

button on the front
panel of the machine, or the

button on the SRC1 handset.
When the machine is initially switched on, a certain amount of time elapses
before all the amplifier stages reach their optimum working point. During this
period the

- and

- button flash (power-on delay). As soon as the
machine is ready for use, it switches speaker outputs A and B to their previous
status, i.e. their status when the amplifier was last switched off.
Selecting sources You can choose your preferred listening source using the source select buttons
(


) on the machines front panel or with the

button on
the SRC1 handset. The set source is displayed on the screen. To select the
source IN 6 or IN 7 directly on the device, press the

button on the front
panel twice if necessary. To select the source using the remote control SRC1 ,
use the  button. If necessary, press the  button repeatedly until
the desired source is shown in the display. Once the source has been selected,
the
PA 2500 R switches to the input with a short delay.
Alternative source selection *: Press and hold the  button to open the
source selection list, then use the

/

buttons to select the desired
source and press the

button to confirm.
Any source device connected to the
PA 2500 R via the

R2
LINK
system can
be controlled using the SRC1 remote control handset once it has been selected
as the listening source.

The source selection via the remote control handset FM2000 differs from the
operation with the SRC1 . With the FM2000 , the listening sources can be
selected using the SOURCE buttons  to  . You may need to press
the

button twice to select the source IN 6 or IN 7 .
Volume adjustment The PA 2500 R features an extremely accurate volume control calibrated to
produce exact channel-matching. The precision audiophile resistors are
switched using gold-contact relays; these components are totally devoid of
distortion and noise, and guarantee absolute maximum resolution and detail
fidelity, even at low listening levels.
The volume level of the
PA 2500 R can be adjusted in fine increments (1 dB
steps) by turning the volume knob (

VOL)
on the machine’s front panel.
Volume can also be controlled from the remote control handset using the
-

+ buttons: each brief press on a volume button increases or reduces
the volume by one increment. Holding either volume button pressed in alters the
volume continuously.

You may hear a subdued clicking sound from inside the machine when you
adjust the volume or balance; this is caused by the gold-contact relays.
Balance adjustment Balance is also controlled using the volume knob (

VOL) on the amplifier. If
you wish to alter the balance, first press the volume knob until the currently set
balance value appears on the screen. You can now adjust the balance setting
by turning the volume knob to left or right. Once the appropriate value is found,
a long press on the volume knob concludes the procedure and saves the value.
The SRC1 handset can also be used to adjust balance: first press the

button to display the the current balance value; the value can now be adjusted
using the

/

buttons. A further brief press on the

button
adopts the value, and the Balance window closes.
*Only possible in stand-alone mode.
