Overview

The Crown T-Series Operation Manual describes a line of commercial audio power amplifiers, including the T3, T5, T7, and T10 models. These amplifiers are designed for professional use, offering robust performance and a range of features for various audio applications.

Function Description:

The T-Series amplifiers are designed to amplify audio signals for loudspeakers. They feature two channels, each with independent gain control, allowing for flexible configuration in stereo (dual), bridge-mono, or parallel modes. The amplifiers are equipped with various indicators to monitor operational status, including Power, Fault, Clip, and Signal Presence LEDs for each channel. Airflow is designed from front to back for efficient cooling, making them suitable for rack-mount installations.

Important Technical Specifications:

The T-Series amplifiers offer varying power outputs depending on the model and configuration:

  • T3:
    • 4 ohms stereo (per channel): 450W
    • 8 ohms stereo (per channel): 330W
    • 8 ohms bridge mono: 900W
  • T5:
    • 4 ohms stereo (per channel): 750W
    • 8 ohms stereo (per channel): 500W
    • 8 ohms bridge mono: 1500W
  • T7:
    • 4 ohms stereo (per channel): 950W
    • 8 ohms stereo (per channel): 675W
    • 8 ohms bridge mono: 2000W
  • T10:
    • 4 ohms stereo (per channel): 1350W
    • 8 ohms stereo (per channel): 1000W
    • 8 ohms bridge mono: 2700W

All models share common performance characteristics:

  • Frequency Response (at 1 watt): 20 Hz - 20 kHz, +0/-1 dB
  • Total Harmonic Distortion (THD): <0.5%, 20 Hz – 20 kHz
  • Intermodulation Distortion (IMD): = / <0.35% (60 Hz and 7 kHz at 4:1, from full rated output to -30 dB)
  • Slew Rate: >10V/us
  • Damping Factor (8 ohms, 10 Hz – 400 Hz): >200
  • Signal-to-Noise Ratio (below rated power, 20 Hz to 20 kHz, A-weighted): >100 dB
  • Crosstalk (below rated power): At 1 kHz: -75 dB; At 20 kHz: -59 dB
  • Input Sensitivity (for full rated power at 8 ohms): 0.775V or 1.4V (selectable via switch)
  • Nominal Input Impedance: Balanced: 20k ohms; Unbalanced: 10k ohms

Connectors, Controls, and Indicators:

  • Input Connectors: One balanced XLR and one unbalanced RCA per channel.
  • Output (speaker) Connectors: 4-pole Speakon® and one pair binding post per channel.
  • Front Panel Controls: Power on/off switch, one gain control per channel.
  • Rear Panel Controls: Output mode switch (stereo/dual, parallel, or bridge), Input sensitivity switch (0.775V or 1.4V).
  • Indicators:
    • Power: One blue LED.
    • Signal: One green LED per channel.
    • Clip (peak): One yellow LED per channel.
    • Fault: One red LED per channel.
  • Power Cord Specifications: Plug: 10A, 250V; Cord: CCC 3 x 1.5 mm².

Construction:

  • Protection: Protection against short circuits, no-load, on/off muting, and RF interference; stable into reactive or mismatched loads.
  • Ventilation: Flow-through ventilation from front to back.
  • Cooling: Internal heat sinks with forced air. Fan cooled, speed regulated, thermal protection.
  • Dimensions (W x H x D):
    • T3, T5: 19 x 3.46 x 12.45 in (482 x 88 x 316.4 mm)
    • T7, T10: 19 x 3.46 x 14.5 in (482 x 88 x 369 mm)

    • T10: 47.4 lb (21.5 kg)

Usage Features:

The T-Series amplifiers are designed for ease of installation and operation. They fit standard 19-inch equipment racks (EIA RS-310B). Proper cooling is emphasized, with recommendations to ensure adequate airflow and spacing in rack installations. The front panel includes a power switch, gain controls for each channel, and LED indicators for quick status checks. The rear panel features input and output connectors, along with switches for configuring the amplifier's operating mode (stereo, parallel, bridge-mono) and input sensitivity. Wiring diagrams are provided for various configurations using Speakon® and binding post connectors, including stereo (dual), bridge-mono, and parallel modes. Bridge-mono mode doubles the output power and utilizes only the Channel 1 gain control. Parallel wiring sends a single input signal to both channels for reproduction by two speakers. The amplifiers require Class 2 output wiring.

Maintenance Features:

The manual stresses important safety instructions, including reading all instructions, keeping the manual, heeding warnings, following instructions, and not using the apparatus near water. It advises cleaning with a dry cloth and not blocking ventilation openings. Servicing should be referred to qualified personnel, especially if the apparatus is damaged or malfunctions. The device is designed with internal protection against various electrical faults and thermal issues. The warranty information outlines a one-year warranty period for defects in materials and workmanship for the original purchaser, with specific exclusions for damage due to misuse, accidents, or negligence. Warranty service is obtained by notifying Crown International and shipping the product to an authorized service center or the factory. The warranty covers repair, replacement, or refund at Crown's discretion and covers shipping costs within the United States. The manual also includes an FCC Compliance Notice, detailing the device's adherence to part 15 of the FCC rules and providing guidance for resolving potential interference issues. It also contains a Declaration of Conformity, listing compliance with various EMC and safety standards (e.g., EN 55103-1, EN 61000-3-2, IEC 60065).
