I-Tech Series Power Amplifiers

3 Operation

3.5Back Panel Controls, Indica- tors and Connectors

A. Fans

Provide front-to-back forced airflow for cooling.

ANALOG INPUTS SECTION

B. Balanced Analog XLR Inputs

A 3-pin female XLR connector for each channel.

C. Balanced Analog XLR Loop-Through Outputs

Two 3-pin male XLR output connectors are pro- vided (one per channel). The signal at these connectors is paralled with the input signal for feeding the input signal to other amplifiers.

OUTPUTS SECTION

D. 4-Pole Speakon Output Connectors

Two high-current, 50A Neutrik® Speakon NL4MLP (mates with NL4FC and NL4), one per channel. Class 2 output wiring required.

These two connectors accept 2-pole or 4-pole Speakon connectors. See Figures 2.5 through

2.10and Tables 1, 2 and 3 for connector wiring. The top Speakon connector is wired for both channels so it can be used for bridge-mono wiring or for stereo wiring of two speakers to a single Speakon connector.

E. Binding Post Output Jacks

One pair per channel of high-current, 60A color-coded binding posts. Accepts banana plugs, wire or spade lugs.

F. Power Cord Connector

Standard 20 amp IEC inlet. Voltage range is indicated above IEC inlet.

G. Reset Switch/Circuit Breaker

If the current draw of the amplifier exceeds safe limits, this breaker automatically disconnects the power supply from the AC mains. The switch resets the circuit breaker.

DIGITAL INPUTS SECTION

H. AES/EBU Digital Input

This 3-pin female XLR connector accepts a dig- ital signal in the AES/EBU format.

I. AES/EBU Digital Loop-through Output Male XLR active/re-clocked AES/EBU digital loop-through. The signal at this connector duplicates the digital input signal for feeding the input signal to other amplifiers.

It is not recommended to loop through more than four amplifiers. If larger distribution of AES is needed, the use of an AES distribution ampli- fier is recommended.

NETWORKING SECTION

J. Preset Indicator

Yellow LED flashes to signal the number of the current preset if active.

K. Data Indicator

Yellow LED indicates HiQnet or IQ data activity. Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online.

L. Network Connector

This Ethernet connector accepts an RJ-45 con- nector for networking. Built into the connector is a yellow LINK ACT indicator that shows net- work activity, and a green 100Mb indicator that shows a 100Mb network connection.
