1166.. VVOOLLUUMMEE CCOONNTTRROOLL
Controls the overall volume level of the amplifier. The final level adjustment should be made after the desired
sound has been achieved.
1177.. LLIINNEE OOUUTT——XXLLRR JJAACCKK
Provides low impedance, electronically balanced signal for patching into a sound reinforcement or recording
console.
1188.. LLIINNEE OOUUTT LLEEVVEELL CCOONNTTRROOLL
Controls the output level of the balanced line out.
1199.. PPRREE--//PPOOSSTT--EEQQ SSEELLEECCTT SSWWIITTCCHH
Allows selection between a Pre-EQ (switch set to the “out” position) or a Post-EQ (switch set to the “in” position)
send to the XLR line out jack.
2200.. GGRROOUUNNDD LLIIFFTT SSWWIITTCCHH
Provided to lift the ground on the XLR jack when ground loops are encountered.
2211.. EEFFFFEECCTTSS SSEENNDD JJAACCKK
Output for supplying signals to external low-level effects or signal processing equipment.
2222.. EEFFFFEECCTTSS RREETTUURRNN JJAACCKK
Input for returning signals from external low-level effects or signal processing equipment.
2233.. EEFFFFEECCTTSS LLOOOOPP RREEMMOOTTEE SSWWIITTCCHH JJAACCKK
This jack accommodates the remote footswitch (optional part number 00051000 ON/OFF single button switch),
which is used to remove the effects loop from the signal path. The remote footswitch essentially acts as a bypass
to punch in or punch out from your external effects.
2244.. DDDDTT
™™
SSPPEEAAKKEERR PPRROOTTEECCTTIIOONN DDEEFFEEAATT SSWWIITTCCHH
DDT
™
speaker protection is defeated when the push button is in the “in” position. We recommend that DDT be
enabled at all times to protect the speakers.
2255.. PPRREEAAMMPP OOUUTT JJAACCKK
This 1/4" jack is used to route the preamp signal to external inputs, such as the input of an additional power amp.
The signal is post volume control. Use of this jack does not defeat the signal to the MAX 450 amp (some volume
difference may be noticed due to the impedance change experienced when adding an external unit to the signal
patch).
2266.. PPOOWWEERR AAMMPP IINN JJAACCKK
This 1/4" jack is used to input an external signal to the power amp section of the MAX 450. Using this jack will
disconnect any signal from the preamp section. Using this jack along with the preamp out jack creates a possible
second effects loop.
2277.. PPOOWWEERR CCOORRDD RREETTAAIINNEERRSS
Use the Power Cord Retainers to wrap and store your cable while storing or transporting your MAX 450. It is best
to disconnect the cord from the unit before wrapping.
2288.. SSPPEEAAKKEERR OOUUTTPPUUTT JJAACCKKSS
These two 1/4" jacks provide the powered signal from the amplifier. Each connector is electrically the same (in
parallel). Use one of the jacks to connect your speaker cabinet and the other to add a second speaker cabinet in
parallel. The minimum speaker load impedance is 2 Ohms (or two 4-Ohm speakers in parallel).

To prevent the amplifier from overheating, the front fan and rear-located vents should always remain
clear of obstructions.
