1.
Two external amplifiers are required to power each HIGH DEFINITION
LINE 4210 box.
The ISP Technologies HIGH DEFINITION AMPLIFIERS are provided for ease of use
and simple connection to a five-way digital crossover box. Make sure that the digital
crossover box is configured with proper ISP Technologies approval, prior to use.
2.
Make sure that all of the proper cables are available. These connections require an 8
conductor speaker cable, 4 con
ductor speaker cable, ¼’ phone cable and XLR cables
with male and female connection ends.
3.
Connect the outputs of the crossover/processor box to the inputs of the first pair of
HIGH DEFINITION AMPLIFIERS (H.D.A. 1003-8 and H.D.A 1003-4) as shown in the
connection diagram. Connect a short jumper from the LOW 1 output to the LOW 2 input
of the second external amplifier.
4.
Connect the Speaker Outputs of the amplifiers to the speakon inputs of the HIGH
DEFINITION LINE 4210 box. 8 conductor and 4 conductor speaker wire must be used
in order to achieve all necessary connections. Also connect the HF jump using a short
¼’ phone cable. This cable brings the HI channel output from the bottom external
amplifier to the speakon connector on the top external amplifier.

Daisy Chain the four outputs from the first pair of external amplifiers to the inputs of the
next pair of external amplifiers. Connect the speaker outputs to the next HIGH
DEFINTION LINE 4210 box.
6.
Repeat this process for all line array boxes until full connection is achieved.
