Operating Manual

Thank you for purchasing a JET CITY AMPLIFICATION product.
Your JCA JetDirect was designed in SEATTLE WASHINGTON,
and meticulously assembled to assure that it meets the highest
quality standards and value.

Please read this manual, and any other equipment to be used with
JetDirect, carefully before use.

IMPORTANT SAFETY INSTRUCTIONS:

JetDirect does NOT provide a speaker load to protect
your amplifier’s output and needs to be used in tandem

with a proper load.

Do NOT operate your guitar amplifier

without a proper speaker load or similar load device.

1. Never use this or associated equipment in damp or wet conditions. No
objects filled with liquids should be placed on the apparatus. When
cleaning, only use a dry cloth.

2. Do not attempt to modify or re-wire JetDirect. Refer all servicing to
qualified personnel.

3. Ensure all associated equipment is switched off and unplugged from the
mains before connecting or disconnecting JetDirect. Do NOT insert
JetDirect into the path between your amp and speaker while the amp is
ON.

4. Always Plug the speaker cable into the speaker cabinet, then JetDirect,
and then the amplifier before turning the amplifier on.

5. Ensure any associated equipment is switched off and unplugged from
the mains in the event of lightning storms or if unused for long periods of
time.

6. Protect speaker cables from being walked on, pinched or having heavy
objects rolled over them.

power supply to operate.

MicSim emulates the tone of a close-mic’d speaker. The output is
balanced and isolated. Use it in place of a traditional microphone in
