Front Panel Controls and Indicators

Bridge Mode Indicator: Yellow LED illuminates when the amplifier is set to Bridge-Mono

mode.

Ready Indicator: Green LED, one per channel, illuminates when the channel is initialized

and ready to produce audio output. Indicator is off when the amplifier is in standby

mode via the IQ system.

Signal Indicators: Three green LEDs per channel indicate the amplifier’s input and out-

put signal levels.

Signal: input signal is above –40 dBu

–20 dB: amplifier output is 20 dB below clipping

–10 dB: amplifier output is 10 dB below clipping.

Clip Indicator: Red LED, one per channel, illuminates when the channel’s output signal

reaches the onset of audible clipping. The Clip Indicator also will illuminate during

Thermal Level Control (TLC) limiting.

Thermal Indicator: Red LED, one per channel, illuminates when the channel has shut

down, or is very near shutting down, due to thermal stress or overload.

Fault Indicator: Red LED, one per channel, flashes when the amplifier output channel

has stopped operating.

Data Indicator: Yellow LED indicates IQ Network data activity. Data indicator flashes

only when the amplifier is polled for data, or is polled to see whether it is online.

Power Indicator: Blue LED indicates amplifier has been turned on and AC power is

available. The LED will flash when the AC line voltage is 15% above or below the

nominal rated range.

AC Mains Present Indicator: Green indicator built into power switch indicates AC

power is present at the power cord and the amplifier circuit breaker is in the “on”

position.

LCD Control Screen and Controls: These let the user adjust the amplifier’s attenuation

and muting, configure the amp, set up and view error monitoring (such as tem-

perature and load supervision), and recall DSP presets. The presets allow the user

to quickly reconfigure the amp for various applications.

LCD Control Screen: Integrated LCD with white LED backlight, controls amplifier setup

and operation.

Normal mode: Attenuation in 0.5 dB steps, Mute/Unmute, Front Panel Lockout.

Voltage Limiter, Average Power Limiter, Pink Noise Generator, AES/EBU Input

Trim, Input Source, Maximum Analog Input, Amplifier Label Edit, CH1 Label Edit,

CH2 Label Edit.

Menu/Exit Button: "Menu" enters the main menu. "Exit" gets out of the Menu.

Next Button: Selects the next item in the Menu.

Prev Button: Selects the previous item in the Menu

Level Controls (Encoders): These two knobs affect the Channel-1 and Channel-2 out-

put levels. They also select Menu items and adjust parameter values that are dis-

played on the LCD Control Screen.

tor.

Back Panel Controls, Indicators and Connectors

The Crown

I-Tech Series offers amazing power, light weight and ease of use for touring sound and installed

sound applications. Onboard DSP provides a wide array of signal processing, greatly reducing the need for

rack components and rack wiring. Onboard DSP features 24-bit, 96 kHz A/D and D/A converters. All models

are compatible with the IQ

Network and TCP/IQ networking. Digital audio and IQ control signals connect to

the amp via a single CobraNet cable in optional CN models, coming soon. Pushbutton DSP presets simplify

the setup for various loudspeaker arrays. The Global Power Supply works anywhere in the world, and offers

PFC (Power Factor Correction). It is a switching power supply for reduced weight. I-Tech amplifiers have the

highest output voltage in the industry (200V peak), which provides clean transient peaks. The 3rd-generation

patented Class I (BCA

) circuitry couples power efficiently to the load and allows low AC current drain. A

front-panel control screen shows advanced diagnostics and status information.
