CAUTION: RISK OF ELECTRIC SHOCK, DO NOT OPEN

The lightning flash with arrowhead symbol within an equilateral triangle, isintended to alert the user to the presence of uninsulated "dangerous voltage"within the product's enclosure that may be of sufficient magnitude toconstitute a risk of electrical shock to persons.

The exclamation point within an equilateral triangle is intended to alert the userto the presence of important operating and maintenance (servicing) instructionsin the literature accompanying the device.

WARNING:TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS APPLIANCETO RAIN OR MOISTURE.

CAUTIONS: To prevent electrical shock, do not use this (polarized) plug with an extension cord, receptacle or other outlet unlessthe blades can be fully inserted to prevent blade exposure.ATTENTIONS : Pour preevenir les chocs electriques ne pas utiliser cette fiche polarisee avec un prolongateur, une prise de courantou une autre sortie de courant, sauf si les lames peuvent etre inserees a fond sans en laisser aucune partiie a decouvert.

FOR YOUR SAFETY PLEASE READ!

THANK YOU!Please read all the safety and operation instructions in manual before operation. Keep this manual for future reference. Also, keep the carton and packing material in case the unit needs to be returned for service.Avoid water, moisture, and heat.Power sources should be as described in the manual and/or marked on the chassis.Exercise caution to avoid situations where power supply cords may be walked upon or pinched.Please exercise reasonable caution; do not drop objects onto your unit or spill liquid into it.

SERVICING

Users should not attempt to service beyond those means described in this manual. All other servicing should be referred to an authorized service agent.

Typical situations requiring service

Obvious mechanical damage from rough handlingLiquid has spilled on or into the unit.Exposure to rain.Unit does not appear to operate normally.Ground integrity has been compromised, service unit to prevent electric shock.

FEATURESUp to 2000 watts - only 28 poundsExclusive TTTM circuitry including "SMPS" (Switching Mode Power Supply) and class "H" output, for performance andefficiency in a high-power, lightweight package.Stereo and bridged mono operationInput balanced/unbalanced "combo" XLR/1/4" TRS"Output Speakon TM and binding postsLEDs for power on/off, speaker output signal level, peak level and protection circuit detectionLimit circuitry for controlling clipping of output signal with excessive input signalRMS detection circuitry for preventing overload at 2ohm operationThermal sensor circuitry to prevent overheating

OPERATION

1. DUAL mode.

- Each channel operates independently in dual mode.- Be certain that the "DUAL-BRIDGE" mode selector switch, on the rear panel, is in the "DUAL" position before operation.- Rotate both volume level controls fully counter-clockwise.- Connect nominal 0dBu(0.775V RMS) input signal and speakers to the outputs. Turn the power on.- With input signal at operating level, slowly rotate the volume level controls clockwise to the desired program level.- Adjust input signal level via the volume level or via the input signal of the external equipment when the peak-LED

illuminates.

* CAUTION: Do not connect A and B channel outputs together in any way.

2. BRIDGE mode.

- Be certain that the "DUAL-BRIDGE" mode selector switch, on the rear panel, is in the "BRIDGE" position beforeoperation.

- Rotate both volume level controls fully counter-clockwise.- Connect nominal 0dBu(0.775V RMS) input signal to the A channel only. Connect speaker load between "+" terminals of

"A" and "B" output connectors as shown on the amplifier rear panel: speaker + to "A +" and speaker - to "B +". Turn thepower on.

- With input signal at operating level, slowly rotate the channel "A" volume level control clockwise to the desired programlevel.

- Reduce input signal level via the volume level or via the input signal of the external equipment when peak-LED illuminates.

* CAUTION: There should be no input into channel B and B volume level must remain in the fully counter-clockwiseposition.

1. Level volume with 21 positions.2. Power on/off switch.3. 2 red peak LED's one for each CH. These indicate when signal is approching clipping. When these LED's flash reduce

input signal level.4. 2 green output signal LEDs one for each CH. These indicates when signal is present at amplifier output.5. Green power LED. Indicates when mains AC power is on.6. Red LED shows that the amplifier protection system is on. This usually indicates excessive heat build up resulting from

improper loading, lower than 2 ohms for excessive time.

1. Input terminal - Combination connector accepts XLR balanced input and balanced or unbalanced 1/4" phone jack. ForXLR connection: pin 1-gnd, pin 2-high (hot, +), pin-3-lo (com, -). For 1/4" Balanced input Tip-high (hot, +), ring-lo(com, -), sleeve-gnd. For 1/4" Unbalanced input Tip-high (hot, +), sleeve-gnd.

2. Line-output connectors - XLR connectors wired parallel to XLR input for patch connection ("daisy-chain") to input ofadditional amplifier(s).

3. Speaker output terminal - Consists of 12 AWG binding post / bnanana type connectors and Speakon TM connectors.As shown in Rear panel, SpeakonTM connectors are only connected to pin 1+, pin 1-. Not connected to pin 2+, 2-.

4. Power cord.5. EMI Filter - Filters electromagnetic waves influenced from alternating current.6. Mode selector - for selection of dual or bridge-mode operation.7. Fan(s) variable speed fans for cool, quiet, efficient operation.

TROUBLESHOOTING


- 8 -

Problems occasionally occur, very often they are due to a simple operational oversight or the like. Performing the followingchecks will enable you to rectify a number of problems without difficulty. If the problems cannot be remedied afterperforming the following checks, please consult an authorized service agent.

The user should not attempt to check the unit beyond that which is described in this owner's manual. All other servicingshould be referred to qualified service personnel. In the event of warrantable malfunction, please contact TsunamiTechnologies directly for referral to an authorized service agent.

The warranty period for this product is three years. In the event that failure is a result of faulty or defective materials orworkmanship, or for any other problems or questions that occur as a result of normal use during this period, we offer you our'After Service' assistance at no additional charge. However, if a malfunction is caused by user's misuse or abuse, the warrantyshall be void and all evaluation and repairs will be chargeable.

Symptom Cause Solution

- The power cord is not plugged in. - Plug in the power cord.- The power switch is not turned on - Turn switch on.

- The volume level is on min. - Adjust volume level.- Speaker cables are not connected. - Connect speaker cables.

- Inappropriate adjustment on input sources. - Re-adjust input levels, channel gainSettings and channel EQ's.

- Incorrect line voltage or grounding - Verify that main voltage is correct and properly grounded.

Power is not on.

No sound.
