7 Specifications

7.1 General

Protection: Audio outputs can be shorted indefi- nitely without causing damage. If communication is lost, the unit will continue functioning as pro- grammed. If power is interrupted, the unit will func- tion as programmed before the AC failure after the power is restored.

Controls: DIP switches and a slide switch are ac- cessible from the right side of the unit for setting the communication format, baud rate, parity and Crown Bus address. Each audio input has a 3-position se- lector (mic/line/phantom-powered mic) and a cali- brated gain control.

Display: A red Enable LED lights when power is ap- plied to the unit. A yellow DSPI (Data Signal Pres- ence Indicator) LED lights when the appropriate command is sent from the system computer or whenever the unit is receiving data.

Connectors

Audio inputs and outputs: 3-pin male removable barrier block connectors. Buchanan® type SSB4L03S cable connector or equivalent supplied.

Crown Bus serial communication: 4-pin male re- movable barrier block connector and chassis ground stud. Buchanan type SSB4L04S cable con- nector or equivalent supplied.

Aux control: 3-pin Switchcraft TB3M. Mates with Switchcraft TA3F cable connector or equivalent.

RS232/422/Crown Local Net: Female DB25.

Stacking inputs: Phono (RCA) jacks.

Auxiliary Control: Output ON applies 10 VDC to pin

3.Input ON is caused by applying 5 to 30 VDC at pin 2. Pin 1 is ground reference.

Power Requirements: 120 VAC, 60 Hz, 20 W.

Dimensions: 19 inches (48.3 cm) wide for standard rack mounting, 1.75 inches (4.4 cm) high, 9.8 inches (24.9 cm) deep behind mounting surface,

0.15inches (3.8 mm) deep in front of mounting sur-

face.

Weight: 8 lbs 13 oz (4 kg).

Finish: Black splatter-coat chassis and front panel.

Construction: 16-ga. steel chassis, 18-ga. steel cover, 0.125-inch (3.2 mm) aluminum front panel.

7.2 Audio

Input Type: Active differential, transformers op- tional.

Input Impedance: Microphone: 4 kohms nominal.

Balanced Line: 20 kohms. Unbalanced Line: 13 kohms.

Maximum Input Level: Microphone: +7 dBu. Line: +32 dBu (0 dBu = .775 Vrms).

Phantom Power: 44 VDC through two 6810-ohm re- sistors, switchable at each mic input.

Common Mode Rejection Ratio: (Typical) 60 Hz-

1 kHz: 55 dB. 20 Hz-20 kHz: 45 dB.

Output Type: Active balanced, optional transform- ers. For unbalanced operation, leave the "–" terminal open.

Output Impedance: 50 ohms per side, 100 ohms bal- anced.

Maximum Output Level: +26 dBu balanced.

Maximum Gain: Mic input: 77 dB. Line input: 52 dB.

Frequency Response: +0/–1 dB from 20 Hz to 20 kHz.

Harmonic Distortion: Less than 0.05% at +4 dBm output. Less than 0.15% at +20 dBm output, 20 Hz to 20 kHz measured at mic input with 40 dB gain.

Noise: Output noise, all inputs off: –80 dBu (106 dB below rated output). Output noise, one line input at 0 dB gain: –80 dBu. Equivalent input noise, mic in- put, 46 dB gain, 150-ohm source: –125 dBu. (Specs are typical, unweighted, for 20 Hz to 20 kHz.)

Crosstalk: Adjacent inputs/outputs at 1 kHz: better than –80 dB. Adjacent inputs/outputs from 20 Hz to 20 kHz: better than –65 dB.

AMB-5, MPX-6, SMX-6 specifications

The Crown SMX-6, MPX-6, and AMB-5 represent a remarkable evolution in material handling and warehouse management technology. These models are part of Crown's extensive portfolio designed to enhance efficiency, reliability, and operator comfort in various industrial environments.

Starting with the Crown SMX-6, this heavy-duty reach truck is engineered for superior performance in tight spaces. It features an optimized chassis that provides improved stability and maneuverability, making it perfect for narrow aisles and dense storage environments. The SMX-6 is equipped with Crown's state-of-the-art Access1 Door, which enhances operator safety and accessibility to the vehicle's controls. Its innovative lift system allows for higher lifting heights with precision and control, reducing load sway during operation. Additionally, the advanced ergonomic design of the operator's compartment minimizes fatigue, promoting longer and more productive shifts.

The Crown MPX-6, on the other hand, is designed primarily for order picking in warehouses. Its low level order picker design helps increase productivity across the picking process. This model features Crown's unique Power Steering technology, which provides precise control and reduces operator effort, making it easier to navigate through aisles and around corners. The MPX-6 also includes integrated LED lights that provide optimal visibility in dimly lit environments, while its lift and lowering functions offer fast and responsive operation. The advanced control system helps simplify training for new operators, promoting safety and efficiency on the warehouse floor.

The Crown AMB-5 is another standout model, known for its versatility and adaptability in various material handling scenarios. This model is engineered for both indoor and outdoor operations, allowing businesses to maximize versatility without compromising on performance. The AMB-5 is equipped with advanced lithium-ion battery technology that offers rapid charging capabilities and longer operational life compared to traditional lead-acid batteries. This feature is a game-changer for operations that demand high uptime and minimal downtime. The vehicle also features a compact design, making it easy to operate in confined spaces while still delivering robust lifting capacities.

In summary, the Crown SMX-6, MPX-6, and AMB-5 are exemplary models in the field of material handling, each offering a blend of innovative features, advanced technologies, and thoughtful design aimed at enhancing operational efficiency, safety, and operator comfort. These machines exemplify Crown's commitment to providing high-performance solutions adaptable to the ever-evolving requirements of modern warehousing and logistics.
