INSTALLING THE AMP

UNPACKING
Unpack your amplifier and inspect for any damage that may have occurred during transit. If damage is found, notify the shipping company immediately. Only you can initiate a claim for shipping damage, though JBL will be happy to help as needed. If the product arrived showing signs of damage, save the shipping carton for the shipper’s inspection.
We also recommend that you save all packing materials for use if you ever need to transport the unit. Never ship the unit without the factory carton and packing materials.
CAUTION: Before you begin, make sure your amplifier is disconnected from the power source

INSTALLING THE AMPLIFIER
Mount the unit in a standard 19-inch (48.3 cm) equipment rack (EIA RS310B). You can also place a single amp on a solid, stable surface or stack multiple amps.
NOTE: Amplifiers should be supported at both the front and rear of the rack.

PROPER COOLING
When using an equipment rack, mount units directly on top of each other. Close any open spaces in the rack with blank panels. (Open spaces will reduce cooling efficiency.) DO NOT block front or rear air vents.
The rack should be a minimum of 2 inches (5.1 cm) away from the amplifier, and the back of the rack should be a minimum of 4 inches (10.2 cm) from the amplifier back panel.

HARDWARE SETUP

Connect your amplifier to the AC mains power outlet using the supplied AC power cord. First, connect the IEC end of the cord to the IEC connector on the amplifier. Then plug the other end of the cord to the AC mains.

WARNING: The third (ground) prong of the supplied AC power cord connector is a required safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.

Make certain the AC mains voltage and current ratings are sufficient to deliver full power to all amplifiers. DSi 2 Series amplifiers use a universal power supply. The AC voltage requirements are 100V-240V~, 50/60Hz (±10%). If the AC line voltage varies outside of this acceptable range, the amplifier’s power supply will turn off and the blue Power LED will flash. The amplifier will turn back on when the AC line voltage returns to safe operating levels.

POWER UP PROCEDURE

When turning on the amplifier for the first time:

1. Ensure all connections are disconnected with the exception of the power cord.

2. Press the amplifier’s POWER button. The Power indicator will light blue and the amplifier will boot as long as sufficient
   mains power is provided.

3. Once boot up is complete, turn the ENCODER counter-clockwise until all amp levels are set to -80dB in the front panel
   LCD. (The Encoders affect the OUTPUT levl of hte Amplifier.)

4. Configure the amplifier as described in .

5. Once the amplifier has been properly configured for the application, turn off the power — by pressing and holding the
   Power button for 2 seconds — then disconnect the power cord.

6. Turn down the level of your audio source.

7. Make all connections as described in “Wiring Input Connectors” and “Wiring Output Connectors” on page 8.

8. Once all connections have been made, reconnect the power cord and turn on the amplifier power.

9. Turn your audio source up to an optimum level. Refer to all device meters and ensure that at no point in the signal chain is the signal being clipped in any way. If any of the amplifier’s Clip indicators light yellow, reduce the source level until the Clip LEDs no longer light.

10. Turn the amplifier’s ENCODER clockwise until the desired loudness or power level is achieved, while making sure the amplifier’s clip LEDs do not light.

WIRING INPUT CONNECTORS
JBL recommends using pre-built or professionally wired balanced cables (two- conductor plus shield). Balanced wiring provides better rejection of unwanted noise and hum, however, unbalanced line may also be used.
Use 6-pin plug-in cable ends at the amp input connectors. A male connector is supplied for each input of your model of amplifier. Additional connectors are available from JBL (P/N 5024623). Figure 4 shows connector pin assignments for balanced wiring and Figure 5 shows connector pin assignments for unbalanced wiring. Note that for bridge mono operation, only the odd-numbered input channels (1,3) should be wired for each bridged pair.
Figure 4b: Unbalanced wiring

WIRING OUTPUT CONNECTORS
Before making any output connections, ensure the power cord is disconnected from the amplifier and carefully review the total impedance for loudspeakers connected to each amplifier output. If multiple loudspeakers are connected to an output (i.e., in series, parallel, or series-parallel), be certain the total system impedance is within allowed specification for the output.
For low-impedance loads, refer to the table below and select the appropriate size of wire based on the distance from amplifier to speaker.

DSI SERIES FEATURES

Please refer to the DSi User Guide for in depth descriptions and instruction on the following features.

CONFIGURING THE AMP
Read how to configure the DSi 2 amplifier for your application using the front panel user interface. This includes assigning input channels, editing internal routing and DSP settings, and configuring output mode settings. DSi 2 Series amplifiers can be configured using the built-in Guided Setup or manually using the individual menu options in the Configure Amplifier menu.
Configuration can also be performed from a PC using HiQnet Audio Architect.

INTRODUCTION TO HIQNET AUDIO ARCHITECT
DSi 2 amplifiers can be set up from either the front panel or from the HiQnet Audio Architect software program. Access to some settings and functionality are only available from Audio Architect.
The latest version of Audio Architect can be downloaded at www.audioarchitect.harmanpro.com. To communicate with Audio Architect, the amplifier must be connected to a TCP\IP network via the rear panel Ethernet port and, in some cases, configured for the network.

INSTALLING AUDIO ARCHITECT & CONFIGURING THE NETWORK

Network settings can be configured from either the DSi 2’s front panel or from the NetSetter software application. DHCP is enabled by default, allowing the DSi 2 amplifiers to automatically obtain an IP address when connecting to an Ethernet switch or router with an active DHCP server, or when using Auto-IP.

USING HIQNET AUDIO ARCHITECT

JBL DSi 2 amplifiers have Digital Signal Processing built in. When using a DSi 2 amp, the loudspeaker processing (crossovers, limiters, EQs, and delays) are in the onboard DSP, making discrete rackmount loudspeaker processing devices unnecessary. This drastically reduces setup time, commissioning, rack space, and costs. The DSi 2’s internal DSP can be used to perform the following:
