2.1 Unpack Your Amplifier

Please unpack and inspect your amplifier for

any damage that may have occurred during

transit. If damage is found, notify the transpor-

tation company immediately. Only you can ini-

tiate a claim for shipping damage.

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)

Rack and rack-mounting hardware for mounting

amplifier .

WARNING: Before you start to set up

your amplifier, make sure you read and

observe the Important Safety Instructions

found at the beginning of this manual.

2.2 Install Your Amplifier

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).

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.

2.3 Ensure Proper Cooling

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.

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.

2.5 Choose OutputWire and Connectors

TechnicalPro recommends usingpre-built or professionallywired, high-quality,two- or four-

conductor, heavygauge speaker wires.Figure 2.5.1 showshow a userwould connect theL-

Series amplifier toa speaker usingthe Speakon™ connector.

Figure 2.5.2 showsanother option usershave when connectingthe L-Series amplifierto a

speaker. Usingbanana plugs, spadeplugs or simplybare wires, auser can connecttwo

speakers to theamplifier.

Using the guidelinesbelow, selectthe appropriate sizeof speaker wiresbased on the

distance from amplifierto speaker.

2.6 Wire Your System

2.6.1 Stereo Mode

Make sure the amplifier is turnedoff and the level controls

are turned down before you wirethe system. Make sure the

stereo/bridge switch is set to stereo.

Typical input and outputwiring is shown in Figure 2.6.1.

INPUTS: Connect the input wiring for eachdesired channel

using either the XLR or 1/4"jacks. Never used both the XLR

and 1/4" jacks simultaneously on asingle channel.

OUTPUTS: Maintain proper polarity (+/-) on outputconnectors.

In Stereo mode the banana plugsshould be connected

vertically in the CH.1 jacks (onewire in the positive and

one in the negative jack). Besure to maintain the positive

/negative polarity when connecting your amplifierto the

speaker. Positive terminal onthe amplifier should be connected

to a positive terminal on thespeaker. The sameshould be done

for the negative terminals.

2.6.2 How to Parallel the Inputs

There are two ways to feedthe same signal to each

amplifier channel:

1. Buy a "Y" cable. Plugthe female end into your signalcable,

and plug the split male endsinto both amplifier inputs.

2. Feed your signal to theChannel-1 input screw terminals.

Using a mic cable or phone-to-phonecable, connect Channel-1

combo jack to Channel-2 combo jack.

2.6.3 Bridge-Mono 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 bridge.

Typical input and output wiring is shown in Figure 2.6.3.

INPUTS: Connect input wiring to CH.1. Never used

both the XLR and 1/4" jacks simultaneously on a

single channel.

OUTPUTS: Connect the speaker across the positive

(+) output terminals when amplifier is being operated

in Bridge-Mono mode. 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.

NOTE: Turn down the Channel 2 level control when

operating the channel pair in Bridge-Mono mode,

as the Channel 1 level control works both channels.
