Input Impedance (nominal):
20 kilohms balanced, 10 kilohms unbalanced.
Maximum Input Level: +15 dBu or +22 dBu, depending on input sensitivity.
Latency (analog, digital inputs): 1.13 mS analog, 1.81 mS digital (96 kHz).
A/D, D/A Converters: 24-bit, 96-kHz Cirrus Logic.
Digital Input: AES/EBU, 16-24 bit, 32-48 kHz. Onboard sample rate converter. Optional CobraNet input coming soon.
Network: Onboard TCP/IQ, compatible with standard 100-Mb Ethernet hardware.
DSP: 24-bit conversion with 32-bit, floating-point DSP processing. Bypass mode available. Has 64 assignable filters with 9 different filter types. Includes all-pass filters, over 2 seconds of delay available per channel, and dual uncorrelated-noise and sine-wave generators.
Load Supervision: Monitors the average impedance on the output of the amplifier. If the impedance falls outside the specified high/low limits, this function alerts the user via the front panel display, and via the IQwic software when amp is on an IQ Network.
Error Reporting: Reports clip errors, thermal errors, fault conditions and load monitoring errors for each channel via the front panel display and via IQwic software when amp is on an IQ Network.
Attenuators: Speed sensitive, continuously variable rotary encoder, 0.5 dB steps, range 0 to 100 dB.
Load Impedance
(Note: Safe with all types of loads):
Stereo: 1/2/4/8/16 ohms.
Bridge Mono: 2/4/8 ohms.
Input Sensitivity: Adjustable in 0.1V steps from 1.4V to 9.7V.
Voltage Gain (referenced to 8 ohm rated output):
I-T4000: 37.0 dB to 20.3 dB
I-T6000: 37.9 dB tp 21.0 dB
I-T8000: 39.3 dB to 22.5 dB
Required AC Mains: Universal AC input, 100-240 VAC, 50/60 Hz (15%).
Maximum AC mains voltage: 277 VAC.
AC Line Connector: Five cordsets supplied with amplifier (USA, UK, Europe, Australia, India).
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 amplifiers 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, illuminates when the channels output signal reaches the onset of audible clipping.
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. |
