QSC Model ISA 300Ti, 2-Channel, Professional Amplifier USED

  

QSC Model ISA 300Ti, 2-Channel, Professional Amplifier USED. This unit came from a large university environment. It is understood to be in working condition unless otherwise specified. Please see pictures for condition and details.

The QSC ISA 300Ti is a professional, two-channel power amplifier from the QSC Installed System Amplifiers (ISA) Series, designed primarily for sound contractors and fixed installation applications. It is notable for its versatility, offering both low-impedance and isolated high-voltage outputs for distributed audio systems.

Here are the key specifications and features of the QSC ISA 300Ti. 44 lb (20.0 kg). 5.25 x 19 x 15.9 inches (133 x 483 x 400 mm). 120 or 230 VAC, 50-60 Hz. Information not consistently available in search results. Output Power (Stereo Mode, Both Channels Driven, 20 Hz-20 kHz, 0.1% THD).

2 ohms (1 kHz, 1% THD). Transformer (XF) Output Power (Stereo Mode, 50 Hz-16 kHz, 0.5% THD). Output Power (Bridged Mono Mode).

8 ohms (1 kHz, 0.1% THD). 4 ohms (1 kHz, 1% THD).

140V or 200V (XF Output). The "Ti" (Transformer isolated) models, including the ISA 300Ti, offer low-impedance outputs plus isolated 25V, 70V, and 100V high-voltage outputs for distributed audio systems, and these outputs are available simultaneously. This allows the amplifier to drive both standard speakers and a distributed system on the same channel, which can reduce the number of amplifier channels required. Includes a DataPort V2 connector for use with DPV2-compatible signal processing accessories (such as the XC-3 Crossover, SF-3 Subwoofer Filter, LF-3 Low Frequency Filter, and certain DSP units). Features comprehensive protection circuitry, including full short circuit, open circuit, DC, infrasonic, thermal overload, RF protection, and is stable into reactive or mismatched loads.

Includes selectable 50 Hz or 75 Hz high-pass filters to protect speakers and prevent speaker transformer saturation. Features rear panel gain controls with 2 dB detents for tamper-resistant operation and repeatable settings. Front panel indicators include power, signal, and clip LEDs. Connectors include XLR and detachable Euro-style input connectors, and covered barrier strip output connectors for safety agency compliance. Utilizes an automatic variable-speed fan with rear-to-front air flow for efficient cooling and quiet operation.

Supports Stereo, Bridge, or Parallel operating modes. Seo tags: QSC ISA 300Ti, professional power amplifier, installed sound systems, 70V 100V amplifier, distributed audio, commercial amplifier, QSC ISA Series.
