JBL SYNTHESIS SDA8300 / SDA4600 QUICKSTART
General Information
IF YOU READ NOTHING ELSE IN THIS GUIDE READ THIS INFORMATION:
WARNING: Before you start to set up your amplifier, read and observe the Important Safety Instructions
found at the beginning of this manual.
The SDA amplifiers come pre-configured to work with the SDEC4500P using the BLU-LINK digital audio signal over
Cat5e Ethernet cables. The amplifiers should not be connected to the home network. Analog audio input comes IN on the
SDEC4500P (up to 12 channels) and OUT on the SDA8300 and/or SDA4600 without going through any Digital to Analog
conversions (up to 20 Channels as standard, expandable to 128 channels).
Two alternate configurations are selected by using the included selection trigger that plugs into the GPIO input on the rear
panel.
The SDA8300 amplifier ships configured for a simple 7-channel system. The SDA8300 can access two (2) additional
configurations. Using combinations of these configurations allows the system to output from a simple 7 x 300 Watt system
to up to 16 x 300 Watts with discrete DSP for each channel with active bi-amp outputs on the Left-Center-Right.
The SDA4600 ships configured for a 4-channel subwoofer (4x600 Watts). Up to two (2) additional configurations can be
accessed for bridged high power subwoofers outputs (2x1200 Watts) with discrete channel DSP for each output. These
are used with the Harman Patented "Sound Field Management" in the SDEC4500P.
The SDEC-4500P controls all DSP and BI-AMP speaker crossover settings and must be configured with either "JBL
Synthesis ARCOS" software or "SDEC Control Panel Software v1.5". Go to www.jblsynthesis.com to download the correct
software.
CAUTION: Before you begin, make sure your amplifier is disconnected from the power source and that all level
controls are set to INF.
Ensure 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 two inches (5.1 cm)
away from the amplifier, and the back of the rack should be a minimum of four inches (10.2 cm) from the amplifier back panel.
Air flow is front to back.
WARNING: The third prong of this connector (ground) is an important safety feature. Do not attempt to
disable this ground connection by using an adapter or other methods.
Fuse
A fuse (F1) located near the IEC power inlet protects the amplifier from excessive AC current draw. The fuse is field
replaceable. Replace with same type fuse; LittelFuse 314 Series F20AH 250V. Please contact JBL Service department for
more information.
Step by Step Setup Guide
1.
Connect Preamp/Surround Processor and SDEC4500P
2.
Connect Blu-Link Digital Audio Link from SDEC4500P to SDA Amplifier(s) using
standard Ethernet Cat5e cables
3.
[Optional] Connect Powered Subwoofers to SDEC4500P
4.
Setup of SDA8300 for Single (8-channel) or Dual unit (16-channel) configuration and
connect speakers
5.
Setup of SDA4600 for Single (4-channel x 600 W) or Bridged (2-Channel x 1200 W) or
Bridged Dual unit configuration and connect subwoofers
Blu-Link Digital Connection
Digital audio is sent in a daisy-chain from one device to the next using a standard Cat5e patch
cable. Connect the OUT from the SDEC4500P to the IN of the first amplifier. Continue with each
amplifier in the system connecting from OUT to IN. Up to 60 Amplifiers can be connected with up
to 128 discrete channels.
