Crown Audio K2, K1 specifications Crown’s Three-Year, No-Fault, Fully Transferable Warranty

K1

K2

“Y” Input: An on/off switch located on

the back panel between the input connectors which, when turned on, parallels the two input channels.

Indicators

TLC: A TLC (thermal level control) LED for each channel which turns on with a dim glow shortly before the amplifier needs help dissipating heat.

Clip: An orange LED for each channel which turns on when distortion of any type becomes audible in the amplifier output.

IOC: A yellow LED for each channel which serves as a distortion indicator. The IOC indi- cators include a pulse-stretching feature that helps make them more noticeable even with rapid transient signals

Signal: A green LED for each channel which flashes dimly when a very low-level signal (as low as 10 mW) is present in the output. They flash brightly when a louder signal (at least 1 watt) is present at the output.

Enable: A green LED that turns on when the amplifier has been turned on and has power. When first turned on, there will be a brief two- second delay while the amplifier performs a quick turn-on diagnostic. Then the Enable indi- cator will turn on to its full brightness. If

no signal is present, the Enable indicator will switch to a dim level.

Input/Output

Input Connectors: One balanced ¼-inch (6.35-mm) phone jack and one 3-pin female XLR connector for each channel.

Input Stage: Input is electronically balanced and employs precision 1% resistors.

Input Impedance: Nominally 20 k ohms, bal- anced. Nominally 10 k ohms, unbalanced.

Output Connectors: Two sets of color-coded binding posts for banana plugs, spade lugs or bare wire (European models do not accept banana plugs.)

DC Output Offset: ±10 millivolts.

Output Signal

Stereo: Unbalanced, two-channel.

Bridge-Mono:Balanced, single-channel. Chan- nel 1 controls are active; Channel 2 should be turned down.

Protection

K-Series amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature, chain destruction phenomena, input overload damage and high-frequency blowups. They also protect loudspeakers from input/output DC, DC offset and turn-on/turn-off transients.

TLC protection circuitry protects the amplifier from excessive heat by subtly and dynamically reducing the gain only when necessary to reduce heat levels. Transformer overheating (an extremely unlikely event) will result in a tempo- rary shutdown; when it has cooled to a safe temperature, the transformer will automatically reset itself. Controlled slew rate voltage ampli- fiers prevent RF burnouts, and input overload protection is provided by the input current limit.

Out-of-band low-pass and high-pass filters pro- tect the amplifier and loads from subsonic fre- quencies below 8 Hz and ultrasonic frequencies above 30 kHz.

Turn On: State-of-the-art “soft start” feature prevents the amplifier from drawing a large inrush current when it is first turned on and no dangerous artifacts are produced by the ampli- fier. (However it is recommended that all equip- ment ahead of the amplifier be turned on first since they may produce turn-on transients.)

Construction

Cast-aluminum front panel with durable finish and Lexan labels. Aluminum chassis with dura- ble black finish.

Cooling: High-performance passive convection cooling system allows the amplifier to drive

2 ohm loads to high music sound levels (6 dB into clip) in a 40° C (104° F) ambient environ- ment .

Dimensions: Standard 19-inch (48.3-cm) rack mount width (EIA RS-310-B), 3.5 inches (8.9 cm) high and 16 inches (40.6 cm) deep behind front mounting surface.

Net Weight:

K1: 32 lb (14.6 kg).

K2: 38 lb (17.3 kg).

Shipping Weight:

K1: 38 lb (17.3 kg).

K2: 44 lb (20.0 kg).

Center of gravity approximately 6 inches (15.2 cm) behind front mounting surface.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty

Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli- fier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown amplifier is warranted to meet or exceed original specifications for the first three years of ownership. During this time, if your amplifier fails, or does not perform to original specifications, it will be repaired or replaced at our expense. About the only things not covered by this warranty are those losses normally covered by insurance and those caused by intentional abuse. And the coverage is transferable, should you sell your amplifier.

See your authorized Crown dealer for full warranty disclosure and details. For customers outside of the USA, please contact your authorized Crown distributor for warranty information or call 574-294-8200.
