Technical Pro’s L- Series 4 way amplifiers provide professional audio amplification for a wide range of application s. These amplifiers feature front panel controls for easy setup and use. Modern power amplifiers are sophisticated pieces of equipment capable of producingextremely high power levels. In addition, L- Series amplifiers include a number of features which require some explanation so they can be used correctly. Please take the time to study this manual sothat you can obtain the best possible servicefrom your amplifier.

2 Setup 2.1 Unpack Your Amplifier
2.2 Install Your Amplifier
2.3 Ensure Proper Cooling
Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for shipping damage.
CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with the power switch in the off position and all level controls turned completely down (counterclockwise).
When using an equipment rack, mount units directly on top of each other. Close any open spaces in rack with blank panels. DO NOT block front or rear air vents. Be sure that cooler air can flow through the rack either from the front of back of the rack.
We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory packing material. You will need: *Input wiring cables (not supplied) *Output wiring cables (not supplied)
!
Use a standard 19-inch (482.6 mm) equipment rack. See Figure 2.2 for amplifier dimensions. You may also stack amps without using a cabinet. NOTE: When transporting, amplifiers should be supported at both front and back.

2 Setup 2.4 Choose Input Wire and Connectors You have two choices of input connectors: 1/4-inch (6.35-mm) phone, 3-pin XLR. You can also use either balanced or unbalanced wiring. Figure 2.4.1 shows balanced connector pin assignments for XLR and phone. Figure 2.4.2 shows unbalanced connector pin assignments for XLR and phone. Both channels should be wired using a common center terminal for ground connection.
!
NOTE: Custom wiring should only be performed by qualified personnel.

2 Setup 2.5 Choose Output Wire and Connectors Technical Pro recommends using pre-built or professionally wired, high-quality, two- or fourconductor, heavy gauge speaker wires. Figure 2.5.1 shows how a user would connect the LSeries amplifier to a speaker using the Speakon™ connector. Figure 2.5.2 shows another option users have when connecting the L-Series amplifier to a speaker. Using banana plugs, spade plugs or simply bare wires, a user can connect two speakers to the amplifier.
Figure 2.5.1 Speakon™ Connector
Using banana plugs, spade plugs or bare speaker wires, a user can connect up to four speakers to the amplifier. When connecting speaker wires to the banana binding post, be sure that you follow the instructions very carefully. These connections will change depending on whether the unit is being operated in Stereo or Bridged mode. In Stereo mode the banana plugs should be connected vertically in the CH.1 jacks (one wire in the positive and one in the negative jack). The same can be done for channels 2,3 and 4 depending on the number of inputs. In Bridged mode CH.1 and Ch.2 are combined and CH.3 and CH.4 can be combined. If the CH.1 and CH.2 are Bridged, than the banana plug should be connected horizontally, along the positive jacks of CH.1 and CH.2. If the CH.3 and CH.3 are Bridged, than the banana plug should be connected horizontally, along the positive jacks of CH.3 and CH.4. Using the guidelines below, select the appropriate size of speaker wires based on the distance from amplifier to speaker. Distance up to 25 ft. 26-40 ft. 41-60 ft. 61-100 ft. 101-150 ft. 151-250 ft.
Wire Size 16 gauge 14 gauge 12 gauge 10 gauge 8 gauge 6 gauge
CAUTION: Never use unshielded cable for output wiring.

2 Setup STEREO
2.6 Wire Your System 2.6.1 Stereo Mode Make sure the amplifier is turned off and the level controls are turned down before you wire the system. Make sure the stereo/bridge switch is set to stereo. Typical input and output wiring is shown in Figure 2.6.1. INPUTS: Connect the input wiring for each desired channel using either the RCA or 1/4" jacks. Never used both the RCA and 1/4" jacks simultaneously on a single channel. OUTPUTS: Maintain proper polarity (+/-) on output connectors. In Stereo mode the banana plugs should be connected vertically in the CH.1 jacks (one wire in the positive and Ch1 one in the negative jack). Be sure to maintain the positive /negative polarity when connecting your amplifier to the speaker. Positive terminal on the amplifier should be connected to a positive terminal on the speaker. The same should be done for the negative terminals.

2.6.2 How to Parallel the Inputs There are two ways to feed the same signal to each amplifier channel: 1. Buy a "Y" cable. Plug the female end into your signal cable, and plug the split male ends into both amplifier inputs. 2. Feed your signal to the Channel-1 input screw terminals. Using a mic cable or phone-to-phone cable, connect Channel-1 combo jack to Channel2 combo jack.

INPUTS: Connect input wiring to CH.1 and CH.3. Never used both the RCA and 1/4" jacks simultaneously on a single channel. OUTPUTS: When operating the amplifier in Bridge mode, only the Banana jacks can be used. In Bridged mode CH.1 and Ch.2 are combined and CH.3 and CH.4 can be combined. If the CH.1 and CH.2 are Bridged, than the banana plug should be connected horizontally, along the positive jacks of CH.1 and CH.2. If the CH.3 and CH.4 are Bridged, than the banana plug should be connected horizontally, along the positive jacks of CH.3 and CH.4. Refer to Section 2.5 for output connector pin assignments. Make sure the Mode switch is set to the "Bridge Mono" position when operating in Bridge-Mono mode.
