Sherbourn Technologies LDS16-40 Caution for Connections, Operating Voltage, Care of the Product

2.If your amplifier is going to be placed in an enclosed space such as an armoire, it is essential that adequate ventilation be provided. We strongly suggest that the shelf on which the product is being placed includes a cutout of at least twenty inches by twelve inches (50 cm by 30 cm) directly under the ventilation slots on the bottom of the amplifier. A similarly sized cutout should be made in the upper or rear wall behind the shelf so that free air can flow from beneath the unit to the outside atmosphere. Also allow a minimum of three inches (7.5 cm) free space above the product and two inches (5 cm) on either side of the product. This combination of space will allow for a free flow of circulating air to help keep the amplifier from overheating. If your cabinet includes a number of products, it may be advisable to install a quiet fan to assist the cooling process.

3.The dealership from which you purchased the product is an expert on custom installation procedures and can provide invaluable advice to help you make an aesthetically pleasing and trouble free installation.

Caution for Connections

1.Connect this equipment only to the type of AC power source as marked on the unit. Always route AC power cords so they are not likely to be walked on, or tripped over, or where they may be pinched by items placed on or against them. Always pay particular attention to cords at plugs and/or convenience receptacles, and at the point where they exit from the product.

2.Do not defeat the inherent design features of the polarized plug. Non polarized line cord adapters will defeat the safety provided by the polarized AC plug. If the plug should fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug. If you use this product in a country which only has two slotted receptacles in the house, you must use a three-pin adapter plug to earth ground which is the “E” (earth pin) of the power cord connected to this product.

3.Do not overload wall outlets, extension or integral convenience receptacles, as this could result in a risk of fire or shock.

Operating Voltage

The LDS16-40 amplifier is factory-set for 110V/ 120V 60 HZ or 230V 50HZ AC operation, according to the country for which the unit was manufactured (230V in European Union countries, in compliance with CE regulations). The operating

voltage cannot be changed by the user and any attempt to do so may risk of causing damage to the amplifier and will void the warranty.

Care of the Product

Clean the product by dusting with a dry cloth. Do not permit objects of any kind to be pushed and/or fall into the product through the enclosure openings.

Front Panel Description

The front panel houses the main Power ON/OFF switch. A blue power LED will illuminate when the LDS16-40 is ON and will dim when all zone amplifiers are in the ‘Standby’mode. The LED will only extinguish when the Power ON/OFF switch is in the OFF position or when the LDS16-40 is disconnected from the electrical outlet.

Rear Panel Connections

The LDS16-40 has been designed to provide multiple stereo zones with identical performance and features. The following descriptions apply to all zones.

The connections of the audio signal between your preamp/control center and your LDS16-40 will be made discretely via cables from the outputs of your preamp to the gold plated inputs of your LDS16-

40.Please ensure that the cables are installed for each channel as described on the following pages.

Volume Controls

Two separate controls are provided for left and right volume control. When functioning under the bridge-mono mode, only the right volume control is used for volume adjustment.

LDS Operation

Each time the power comes on, the LDS16-40 will perform the LDS (Load Detection System) test sequence from zone-1 to the last zone amplifier. Sherbourn’s LDS technology incorporated in this product will automatically detect a short-circuit in the speaker wiring and will also check for speaker(s) that may be configured with too low an impedance of less than 4 ohms typically. During the test sequence, observe the rear panel LDS LEDs for the following test results.

The power should be off during your installation. Once your installation is complete and the unit is powered up, the LDS16-40 will automatically perform the LDS Test Sequence described in the previous paragraph. Please note
