Fig. 1A - P-2200 Front Panel
Fig. 1B - P2201 Front Panel
A. Input Attenuators
Calibrated, stepped input attenuators lower input
signal levels ahead of amplification stages.
B. Peak Reading Meters (P-2200 only)
Meters display instantaneous (peak) power output
into an 8-ohm load over a full 50dB range; "0dB" =
100 Watts into 8 ohms.
C. Thermal Warning Indicator
Warns of overheating before thermal protection
circuit turns off the AC power.
D. Power Indicator
Glows when the power switch is "on."
E. On-Off Switch
Controls AC power to the P-2200 or P2201.
NOTE: The P2201 is identical to the P-2200 except
there are no Peak Reading Meters. Both are made to be
mounted in a standard 19" wide electronic equipment
rack. Each of them takes up 7" (17.6cm) of vertical
space, and extends 13" (33.0cm ) behind its front panel.
For portable racks, we recommend bracing the rear of
the amplifiers.
