AMPS, SPEAKERS AND IMPEDANCE

The JCA100H performs optimally with a 16ohm load. You may
also operate this amplifier in conjunction with additional speaker
cabinets for total ohm loads of 8ohms or 4ohms.

QUICK SETTINGS FOR SELECTED TONES

• CLEAN SETTINGS: Set the NORMAL Master to about 6 to
maximize the amplifiers extended headroom. Now simply
use the NORMAL Preamp control to achieve the desired tone
and volume.

• HIGH GAIN SETTINGS: Switch to the OVERDRIVE channel.
Initially, the OVERDRIVE Master should be set to a low level
(somewhere between 1-3) and the OVERDRIVE Preamp
turned up to give the desired gain and distortion. Then
return to the MASTER control to set the desired loudness.

• REMEMBER TO EXPERIMENT: This is how you will get the
most out of your new amplifier.

BEFORE YOU ROCK

Back to some serious stuff rock boy or rock girl. Before operating
your JCA100H please make sure of the following:

WARNING: If a speaker or suitable “dummy load” is not plugged into
the speaker jack, output transformer failure will occur. OUCH! This is
not good and NOT covered under warranty.

• First, plug the JCA100H head into a speaker cabinet.

• Plug the power cable into the back panel and plug the cable

into a power receptacle. Turn on the power switch on the amplifier
and wait about 30 seconds for the tubes to warm up.

• Turn on the standby switch.

• Turn up your volume switch on your guitar and impress your

friends with your amazing new tone.

WELCOME TO THE JET CITY JCA100H – 100W
HEAD

The Jet City Amplification JCA100H is a 100 watt, 2-channel

guitar amp head with independent preamp and master volume

controls for each channel.

The tone controls shape the sound of both channels and

are interactive — meaning each control will affect the

others. This gives you the flexibility to dial in all the unique

and subtle tones you've been searching for.

The Jet City Amplification JCA100H 100 amp head also has

a global presence control that lets you add high-end

sparkle to both channels. Other features include a line

level series effects loop, multiple speaker impedance

outputs, and a channel footswitch jack (footswitch

included).

MJ – RIP from ‘333’

GENERAL OPERATION

The JCA100H’s shared EQ controls allow you to dial up the
right tone for you and your guitar no matter what your
gain and output levels. The two independent preamp and
master controls give you great stage versatility by allowing
you control over each channel’s gain level, AND individual
output levels.

FEATURES

• 2-Channels with independent preamp and master volume

controls Normal and Overdrive

• 100 Watts of Tube Power

• Tube-buffered serial effects loop

• Multiple speaker impedance outputs

• Footswitch for channel switching

• NORMAL Preamp Gain: Adjust the amount of gain (distortion) that

the amplifier produces in the NORMAL Channel.

• OVERDRIVE Preamp Gain: Adjust the amount of gain (distortion) in

the OVERDRIVE Channel. The higher the preamp setting the more

overdriven the sound will be.

• BASS, MIDDLE and TREBLE: allow you to control the tone.
