REVERB CONTROL / REVERB ON SWITCH / LED Set the REVERB control for the overall amount of Reverb available. Then for each channel 1-3, press the REVERB SWITCH to select which channels you want the Reverb working. The "ON" LED will show Reverb is active for the channel you are currently using. When you come back to that channel, the amp will remeber if the Reverb should be On or Off. The REVERB circuits are located after the EFFECT LOOP and before the MASTER. The REVERB can also be turned on/off through the rear REVERB footswitch 1/4" jack, or by MIDI control. 20. STANDBY SWITCH Use the STANDBY SWITCH If you are taking a break. This turns the high voltage off, increasing the life of your power tubes while keeping the power and preamp tube filaments on for immediate use. 21. POWER SWITCH & INDICATOR The power switch is to be utilized as the master ON/OFF switch. As the amp is turned on, the RED portion of the power switch will illuminate as your ON indicator. REAR PANEL 22. SPEAKER JACKS Two 1/4" SPEAKER JACKS are featured to operate several speaker systems at the same time. Calculate the total speaker impedance based on parallel wiring as both speaker jacks are wired in parallel. Select the IMPEDANCE SWITCH for the correct impedance. 23. SPEAKER IMPEDANCE SWITCH The SPEAKER OHMS switch offers the selection of 4, 8 or 16 ohms ( ) to match your speaker systems. The correct setting for one C412 cabinet is 16 . For use with two C412 (16 ohm) cabinets, the correct setting would be 8 . In the case of connecting two 8 ohm systems such as the C212E 8 ohm extension cabinet, move the switch to 4 ohms. 24. RMS POWER SWITCH The 3-position RMS POWER switch reduces the 100 watt output of the amp down to 50 or 15 watts, while still using all four output tubes. Lower settings will allow the great sound and feel of the tube power amp being overdriven, but at lower volume levels. For maximum output power and headroom set the switch to 100 watts. For early power amp saturation move this switch to 50 or 15 watts. The maximum volume reduction will only be 3dB and 8dB respectively. 25. POWER TUBE BIAS SWITCH If you desire to change from EL34 to 5881 (6L6GC) power tubes, you may do so by selecting the external BIAS switch to the 5881 (6L6GC) position on the rear panel. Be sure that this switch is selected to the proper position or excessive heat will damage your tubes. We recommend re-biasing when changing power tubes. The internal P11 bias trim control can be set by a qualified technician. To set the bias, measure the current across the terminals of the STANDBY switch (set this switch to the off position when the amp is on). Set the idle current to 100 mA for all tube types. 26. VOICED LINE OUT The LINE OUT 1/4" jack is "CABINET VOICED" to prevent excessive bass or highs going to your mixer. This greatly aids in sound quality because you do not have to move your mixer EQ settings to the extreme. The 1.5 VAC output (reference to 100 watts output at 8 ohms) is more than adequate to drive any professional mixer or power amp. 27. FS44M FOOTSWITCH JACK (NOT a MIDI JACK) Connect only the Carvin FS44M to this jack. Other devices will not work and may cause damage. The FS44M will allow you to remotely choose channel 1, 2 or 3 and activate the master BOOST function. The LEDs on the FS44M indicate your selections, and will also reflect changes made through the MIDI IN jack. 28. REVERB FOOTSWITCH JACK (FS22) The front panel REVERB on/off feature will follow (track) your channel selection or MIDI, however you may want to switch it manually with a footswitch. Connecting an FS22 will allow you to toggle the REVERB on/off. Other basic footswitches with a 1/4" plug will work. 29. MIDI IN / MIDI THRU Connect any standard MIDI controller to the MIDI IN jack with a 5-pin MIDI cable. You can connect other MIDI compatible devices to the MIDI THRU. (See MIDI PROGRAMMING at the end of this page.) 30. EFFECTS LOOP: SEND and RETURN For the lowest possible noise from an effects processor, use the EFFECT LOOP SEND and RETURN. To use the EFFECTS LOOP, plug the INPUT of your effects into the SEND jack and the OUTPUT of your effects into the RETURN jack. Use shielded cables, not speaker cables. It's possible to have a slight gain reduction of a few dB with some effects units. However, the amp has plenty of gain to overcome any loss. The SEND jack levels will not be affected by the MASTER control. 31. MASTER OUT and POWER AMP IN The MASTER control affects the MASTER OUT jack level to allow control of multiple amps from a single knob. Signals sent into the POWER AMP IN feed directly to the power amp section and will have no volume control. These jacks can also be used as an effects loop, however if you are using dynamics based effects that rely on very specific signal level settings (compressor, auto-wah) it is recommended to use the EFFECTS LOOP instead. 32. AC POWER & FUSE First, make sure the AC VOLTAGE switch is set for the voltage in your area. The detachable AC POWER CORD supplied is designed to operate with one type of voltage (for European 230VAC use a CEE-7 plug cord set). Make sure the cord is securely inserted into the back of the unit. Plug the cord into a grounded "3 prong" power source. No attempt should ever be made to defeat or use the amp without the ground connected. The fuse is located inside the AC jack. 33. AC VOLTAGE SELECTOR BEFORE you insert the AC cord into it's receptacle, make sure the AC voltage switch is set for your region (120VAC in the USA), and remove the warning label. The wrong setting may cause severe damage to your amp and will not be covered by the warranty. For the 240VAC setting, replace the fuse with a 3A fuse before operating. 34. LED SET BUTTON The Legacy 3 has internal LED lighting that can be set to change color with channel selection, by MIDI presets, or by CC control. To change the LED backlighting color: 1. Press and hold down the channel switch you want to change the color for. (1, 2 or 3) 2. While still holding the first switch in, press in the other two switches, then release all switches at once. 3. On the back panel, press and release the "SET LED" button to set the lighting color to GREEN, RED, AMBER or OFF. 4. Press and release any channel (1,2,3) button to save and exit. Normal operation is resumed. - SEE NEXT PAGE FOR MIDI SETTINGS -
