PowerShare PS602P
The PS602P is a 2-channel portable amplifier that allows its total 600 watts to be shared asymmetrically across both
outputs. Independently control the output level, EQ, and low-impedance/high-impedance (Low-Z/Hi-Z) settings for
each output. The PS602P supports built-in loudspeaker EQs for the FreeSpace DS 16, DS 40, DS 100, FS3B, Panaray 402
and 802 Series IV, MA12EX, and RoomMatch Utility RMU105 and RMU108, as well as a Flat setting for FS3 systems. For
applications that require more customization, access the advanced digital loudspeaker processing features using the free
web-downloadable PowerShare Editor software.

q POWER Switch - ON/OFF AC power.
w POWER LED - Solid green LED indicates the unit is ON. Blinking green LED indicates the unit is in lower-power mode.
Solid amber LED indicates an over-temperature fault. A solid red LED indicates a power supply fault.
e y INPUT 1 & 2 SIGNAL LED - Each LED operates independently.
Relative to each line-level balanced Euroblock input:
• If the SENSITIVITY DIP switch is set to 4 dBu, then the LED is green from -40 dBu to 9 dBu, with a typical input of 4
dBu. LED is amber from 9 dBu to 12 dBu. LED goes red, indicating input clipping, over 12 dBu.
• If the SENSITIVITY DIP switch is set to 12 dBu, then the LED is green from -40 dBu to 17 dBu, with a typical input of
12 dBu. LED is amber from 17 dBu to 20 dBu. LED goes red, indicating input clipping, over 20 dBu.
Relative to each line-level unbalanced RCA input:
• If the SENSITIVITY DIP switch is set to 4 dBu, then the LED is green from -54 dBV to -5 dBV, with a typical input of
-10 dBV. LED is amber from -5 dBV to -2 dBV. LED goes red, indicating input clipping, over -2 dBV.
• If the SENSITIVITY DIP switch is set to 12 dBu, the LED is green from -54 dBV to 3 dBV, with a typical input of -2 dBV.
LED is amber from 3 dBV to 6 dBV. LED goes red, indicating input clipping, over 6 dBV.
Both LEDs will display solid red if a power supply fault is detected.
r u OUTPUT 1 & 2 LIMIT LED - Each LED operates independently.
• LED is amber when the amplifier is limiting the corresponding output due to exceeding the specified loudspeaker
Vpeak or Vrms limits.
If the sum of the amplifier outputs exceeds 600 watts, then the amplifier will limit all outputs equally, and all LEDs
will show limiting simultaneously. This is because the amplifier is also measuring and limiting total output power, in
addition to individual channel output power. The amplifier is capable of delivering one-third (1/3rd) average power
continuously, 200 watts.
• Each OUTPUT LIMIT LED will display solid red if there is an EHF fault on the corresponding output.
• Both LEDs will display solid red when all outputs are muted due to an amplifier fault, or if there is a power supply
fault.
• Both LEDs will bink red when all outputs are muted from the rear panel mute connector.
t i OUTPUT 1 & 2 LEVEL Control - Output attenuator for each output. Turn the controls clockwise to decrease
attenuation and counter clockwise to increase attenuation. Fully clockwise is 0 dB attenuation, fully couter-clockwise is
mute. The controls are marked in dB of attenuation. There are 21 detents with the first 12 steps spaced by 1 dB, the next
two steps spaced by 2 dB, the following two steps spaced by 3 dB, and the last two steps spaced by 4 dB, for a total
attenuation range of 30 dB prior to muting. The two most counterclockwise steps are mute.
