Sub Level Output (with high pass Pull-Switch)

This control is a RIVERA exclusive feature. This control varies the output level of the

Sub Woofer output circuitry the feeds a full range low source impedance signal to Sub

Woofer Output jack (see rear panel features) to an external Powered Sub, like our Sub

1 or Sub 2 powered Sub Woofer cabinets. It also can be used as an Auxiliary Send to a

Mixer, Recorder, PA System, and a sub-Woofer system that utilizes it’s own electronic

crossover and separate power amp, like our Rivera LB-212 Sub Cab and a Rivera TBR-

5, 320W Power Amp (requires a separate non-Rivera made electronic crossover). This

signal is dry, meaning any signal present in the effects loop return, will not be in the

signal stream from this jack. The internal power amp of the Knucklehead Reverb is

normally a full range signal, with all of the frequencies of the amplifier powering the

Speaker Output jacks. When the Sub Level control is pulled, a high pass filter

frequency dividing network is activated, with the internal power amp only reproducing

the frequencies higher than the frequencies that the Sub 1 or Sub 2 powered Sub-

Woofers are optimized for. This gives you an increase in dynamic range and definition

of the normal speakers connected to the Knucklehead Reverb. This is because they no

longer have to handle the fatiguing low frequency energy. This switch was provided for

players to have a choice in tones, or to be able to use the Knucklehead Reverb without

a subwoofer speaker system.

Focus

This control is another RIVERA exclusive that actually lets you change the speaker's

response characteristics, from tight to loose. The effect can give closed-back cabinets

a sound more akin to an open one, and vice-versa, plus you can "custom blend" the

amount of hardness your final sound has. This function is independent of the use of the

Sub Woofer Output, and even with the Sub Level control pulled, it will continue to affect

the Knucklehead Reverb speaker output damping.

Presence

The Presence control is incorporated as a vital part of the power amp section. Think of

it as a final brightness control after all the EQ, distortion and effects.

Standby

By turning the Power on and the Standby off (the down position, labeled with a '0'), you

can warm up the amplifier before applying full voltage to the Preamp and power output

tubes. This prolongs tube life. Using the Standby switch when you're taking a break

also helps to extend the tubes' life, plus it keeps the amp constantly at the ready. Just

flip the Standby switch to the up ('I') position, and you're ready to play.

Power

This is your main power switch. The on position is indicated by the light being

illuminated. The off position is marked by the "0" on the switch. Before turning the amp

on, always check that a speaker is connected and that the power cord is firmly plugged

into the amp and the outlet.
