Congratulations on your purchase of the PGA18H.The KLDguitar PGA18H has many special features , which let PGA18H go from a
roar to a whisper, shaking the boards on stage, tingling spines in the studio, and raising goose-bumps in the still of night - even during
silent recording. Its three-step power soak brings the sound of the big stage into small clubs and your bedroom. lending power soak
with Pentode/ Triode, player can obtain from 18w to 0.5w power. Enable a reduction of power from 18w down to 0.5w. With the built-in
Red ox and silent recording capability, you can lay down pro-quality tracks at any time day or night.

1. INPUT:(1)
The Input jack will accept signals from all types of guitar pickups, e sure to use a high-quality shielded cable to connect the guitar to

the amplifier
2. LEAD/NORMAL:(2)
Allows selection of the Lead or Normal channel
NOTE: Channel selection may also be achieved by the remote footswitch. If remote selection is desired, the channel switch must be
in the ”in”(lead) position
3. VOLUME:(3)
Normal channel volume control
4. GAIN:(4)(LEAD)
Lead channel level controls
5. VOLUME:(5)(LEAD)
Lead channel volume controls. The final level adjustment should be made after the desired sound has been achieved
6. REVERB:(6)
Reverberation is an echo effect. Rotate clockwise to increase the effect
7. BOOST SWITCH:(7)
“ oost”The overall system gain; Depress to the “in” position to activate
8. BASS:(8)(EQ)
Passive tone controls that regulate high, mid, and low frequencies respectively
9. MIDDLE:(9)(EQ)
10. TREBLE:(10)(EQ)
11. MASTER:(11)
12. PRESENCE:(12)
Presence volume control
13. SEND (13) (EXTERNAL)
Output for supplying signal to external effects or signal processing equipment.
14. RETURN (14) (EXTERNAL)
Input for returning signal from external effects or signal processing equipment
15. STANDBY / LIGHT(15)
Green means working, Red means standby.
16.POWER SOCKET and ON/OFF
Switch to position “I” to activate;”O” to OFF, This is the receptacle for an IEC line cord, which provides AC power to the unit. Connect

the line cord to this connector to provide power to the unit. Damage to the equipment may result if improper line voltage is used. (See
line voltage marking on unit).
17. PENTODE /TRIODE SW
Enable a reduction of power by half. Combine with power soak. Power reduction to 18w, 9w,2.5w ,0.5W power.
18. POWER SOAK
Use this knob to adjust the PGA 18H’s output power and set its basic volume level. This feature lets you enjoy the benefits of full-blown
power amp saturation at low volume so you can play at home in your living room without disturbing your neighbors. Its silent recording
capability lets you capture genuine tube-driven tone via a mixing console without speakers. And if you want to rehearse in silence any
time day or night, simply plug a set of headphones into the mixer. The POWER SOAK is not just about managing volume; it’s also about
conjuring the right tone and response. For modern sounds that demand fast, tightly focused response, set the POWER SOAK to full
power and turn the MASTER knob down. If you want classic rock sounds replete with spongier power tube saturation, drop the POWER
SOAK down to a lower setting and crank the MASTER knob to give those power tubes a workout. The POWER SOAK offers the following
modes:

Normal operation - full power at 18 watts
Power reduction to 4 watts
Power reduction to 1 watt
Speaker off
19. SMPT
SELF MONITOR PAIR TUBE. When amp is on without guitar connected, if SMPT LED lighted, it mentioned you that power tubes did not
matched. It is better to replace them.
20. FOOT SWITCH (20) (EXRERNAL)
Provided connection of the optional remote footswitch. Footswitch is used to select the lead or Normal channels and defeat reverb.
When using remote foot switch, always insert the plug fully (second click) to ensure proper operation.
21. OUTPUT:(21)
Provide for connection of external 4ohm speaker cabinet.
22. OUTPUT:(22)
Provide for connection of external 8ohm speaker cabinet.
23. OUTPUT:(23)
Provide for connection of external 16ohm speaker cabinet.
NOTE: The way connect with speaker
(1) Connect three speakers at same time, The impedance of each speaker must 12ohms
(2) Connect with two speakers in the meantime, If you use INPUT 21 and 22 (4ohms and 8 ohms), The impedance of each speakers
is 4 ohms. If you use INPUT 22 and 23 (8 ohms and 16ohms),The impedance of each speakers is 8ohms
(3) If you only connect one speaker, please connect according to the impedance.
24. DI:(24)
XRL DI out for recording. The RED OX has for years set the industry standard for analog guitar DI boxes with built-in speaker
emulation. It converts the PGA 18H’s speaker out signal, which is tapped post power amp and pre POWER SOAK, into a balanced,
frequency-compensated signal that you can patch directly to a mixing or recording gears. This signal it sounds very authentic, much
like that of a guitar amp, when rendered by a PA or studio monitors. The channels’ MASTER settings directly affect the signal level,
but the selected POWER SOAK mode does not.
