Front Panel Indicators
Bridge Mode Indicator: Yellow LED illuminates
when the amplifier is set to Bridge-Mono mode.
Ready Indicator: Green LED, one per channel, illu-
minates 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 output 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, illumi-
nates 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, illu-
minates when the channel has shut 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 HiQnet/IQ
TCP/IP 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.
Back Panel Indicators
Data Indicator: Yellow LED indicates HiQnet/IQ
TCP/IP data activity. Data indicator flashes only
when the amplifier is polled for data, or is polled to
see whether it is online.
Preset Indicator: Yellow LED flashes to signal the
number of the current preset if active.

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 compo-
nents and rack wiring. Onboard DSP features 24-bit, 96 kHz A/D and D/A con-
verters. All models are compatible with the HiQnet Network and TCP/IQ net-
working. Digital audio and HiQnet/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 tran-
sient peaks. The 3rd-generation patented Class I (BCA
®
) circuitry couples
power efficiently to the load and allows low AC current drain. A front-panel con-
trol screen shows advanced diagnostics and status information.
