Data[edit]
General
* Manufacturer: Parasound * Model: HCA2200 * Year of manufacture: 1992 * Made in: USA/Taiwan * Color: Black anodized * Type: Stereo bridgeable, Analog * Remote control: No * Power consumption: At nominal load approx. 1000W * Dimensions: 19" rack, 4 U * Weight: approx. 38kg * Original price approx.: 3850DM
Connections
* Number of inputs: ** 100kOhm RCA, shorting jumper in XLR input PIN1-3 is required when used. 200kOhm XLR balanced ** Signal ground hard grounded, no ground lift
* Number of outputs: ** One output per channel via screw terminals
Technical Data
* Continuous power 20Hz...20kHz, <0,05% Gesamtklirr ** 8 Ohm: 2x250W ** 4 Ohm: 2x385W ** 2 Ohm: 2x385W (thermische Grenze bei Sinus-Dauerton an 4 Ohm unter Laborbedingungen) ** Im Brückenbetrieb ensprechend höhere Leistung bei doppelter Impedanz.
* Gesamtklirrfaktor: 0,05% bei Nennlast, 0,0009% bei typischen Pegeln
* Dämpfungsfaktor: Werksangabe: >1000@20Hz. measured: 1300@20Hz, decreasing to 150 at 45kHz
* Frequency response: 2Hz...95kHz +0/-1.5dB, 2Hz limited by DC servo.
* Signal-to-noise ratio: >114dB IHF-A, inputs short-circuited * Stereo channel separation: 84dB@1kHz, 74dB@20kHz
Special Features
* DC Servo, an integrating OP at the input controls the DC offset at the output to zero * 2x1,2kVA toroidal transformer * 4x 25.000µF filter capacitors Richey * Componentry ** Input stage: AD712 for balancing ** Driver stage: 2SK405/2SJ115 ** Output stage: 2SC3263/2SA1294, 7 pairs per channel! * Inrush current limiter by means of thermistor at mains input * Protection circuit against overheating, overcurrent as well as DC voltage at the output</0,05%>
