12. Input Jack (1/4” mono) – Plug your main audio signal in here.
13. Auxiliary Input Jack (1.35mm Stereo) – This input feeds the headphone
amplifier only. Plug your music storage device in here.
14. Headphone Output Jack (1/4” Stereo) – Plug your headphones in here.
15. Balanced Line Output (Male XLR) – This is an instrument level, balanced
output intended to drive the input of a mixing board.
16. Speaker Output Jack (Dual 1/4” mono) – Connect your speaker cabinet here.
17. Power Switch – turns mains power to the internal circuitry on and off.
18. Power Cord receptacle – Always use the appropriate power cord for the
region in which you will be playing. The current rating should be adequate to
sustain a minimum of 600W of continuous power being drawn from the line.
Making Connections
Refer to Connection Guide to the right
MAKE SPEAKER CONNECTIONS FIRST
• Use a minimum of 14AWG stranded wire a maximum of 10 feet in length. Longer
cable runs should use heavier wire. The speaker wires should be twisted in order
to minimize radiated noise at the power amp switching frequency. Do not use
shielded cable.
• The power amplifier operates in Bridge-Tied-Load configuration. Therefore, it
is important that no ground connections are made in the power amp-to-speaker
connection.
• WARNING – Do not connect to speaker loads totaling less than 4Ω.
CONNECT INPUT SIGNAL LINES - Use high-quality, shielded cable and ¼” phone plugs.
PREPARING FOR USE
• Turn Level control down
• Connect AC cord. Observe all precautions noted in safety information.
• Actuate power switch. The two Red LEDS will light for a few seconds and then
the Blue power LED will light, indicating that the amplifier is ready to use.
• If either or both Red LEDs remain lit, turn power off and check speaker
cables for short circuits. Power can be applied with the speaker cables
removed to verify the presence of a short and to isolate which cable has a
problem.
• Set up proper input level by observing the Preamp Clip indicator (3rd LED)
and turning up the output of the preceding audio device until the Preamp Clip
indicator just begins to light on the highest peaks of your playing. It may be
necessary to readjust this after setting up the EQ on the PS200.
• Turn the Level control up slowly as you begin playing. Adjust for desired
loudness.
WARNING! This amplifier is capable of producing very high sound pressure levels.
Continued exposure to high sound pressure levels can cause permanent hearing
damage. Set the Level control for a safe listening level or use hearing protection.
• Adjust Global EQ to compensate for any room anomalies and to fine tune your
sound.
SHUTTING DOWN:
• Turn power switch to “Off” position before removing any cables.
WARNING! - Amplifier housing may be hot after extended, high-power playing
sessions. Allow adequate cooling time before handling.
