I. Introduction

The ACS-400 Audio Controller is comprises of eight audio amplifiers that can be configured for microphone or line input. Each output is a balanced +4 dBm configuration. Each amplifier level can be remotely controlled by use of a companion REM-400 remote control panel. This panel also has provision to remotely turn on and off channels with mute status. The ACS-400 also has a remote dimming function of any combination of channels. Dim levels can be adjusted by placing a jumper on the motherboard for each channel. Factory default is 20 dB of dimming. Suggested uses include adding additional microphone inputs to a console, control of 5.1 multi channel audio monitoring, or in any application where remote control of level and on off control is required.

II. Unpacking and Inspection

Carefully inspect the unit after unpacking and make certain that no damage has occurred during shipping.

If damage is noted, contact the shipper immediately and file a claim for damages. Each unit is carefully packed and carries full insurance against damage. Inspect the packing list and make sure that the contents of the package match those described on the packing list.

III. Installation and Connections

As shipped from the factory, the ACS-400 is designed to accept +4 dBm balanced audio and produces +4 dBm balanced audio outputs when connected to an accompanying ACS-REM remote panel. If this optional panel is not used the output level from the ACS-400 unit will be +10 dBm. This is due to the internal gain structure and use of voltage controlled amplifiers within the unit. There is provision to change the input level sensitivity from +4 dBm to -55 dBm if desired for microphone input use. To do so, remove the top cover and locate the Audio Controller motherboard. To set the input levels to – 55 dBm level sensitivity locate the attenuator jumpers which are just to the rear of each module. Place a pair of jumpers in the right hand most set of contacts for each channel that microphone level is desired. Next, feed a -55 dBm signal to the desired input and adjust the trimmer control on the desired module channel for +10 dBm with the remote control full open. This will insure that +4 dBm can be attained with sufficient room in the remote control volume control to boost level if desired.

Connection to the unit is via the three DB-25 connectors. Inputs are connected to the input connector utilizing a standard DB-25 to XLR breakout cable with female XLR connectors utilizing the Tascam®

ADAT format. Cables for this purpose are available from Broadcast Devices, Inc. or can be purchased from a reseller. Outputs are taken from the “Output” DB-25 connector again utilizing a standard DB-25 breakout cable with male XLR connectors. Remote control connections are made via the “Remote” connector. The following remote control and status are available:

Global Mute

– simultaneously for all channels

Stereo pair mute -

with corresponding status to light an LED for channels 1 / 2 , 3 / 4, 5 / 6 and 7 / 8

Global Dim

– all channels simultaneously by 10, 20, or 30 dB

Remote level -

control for each of eight channels

When the ACS-400 is used in conjunction with the ACS-REM series remote control panels simply connect a standard male to female 25 conductor cable Pins 1-25 identical on each end.

See the remote control/status chart for connection information if the ACS-REM panel is not used.

IV. Features and Operation

4

The ACS-400 contains eight balanced input to balanced output amplifiers. Each channel has provision for remote control of level using voltage controlled amplifier techniques. Each pair of channels can be turned on and off remotely and there is also provision for a programmable global on/off control of channels. There is also provision for each channel to be dimmed by 10, 20 or 30 dB. This is also a programmable feature whereby any combination of channels can be dimmed by one remote control command. Each remote control command of on/off and dimming function can be programmed to accept a momentary closure for a toggle function or for a maintained closure for operation.

Standard factory default input level for the ACS-400 is +4 dBm balanced connection. The unit can also be modified to accept -55dBm sensitivity for microphone input use. Standard output level is +4 dBm balanced. Each output is servo steered such that grounding one of the balanced outputs will not cause any damage or loss of level.

For command lines a simple momentary or maintained closure to control common ground will activate the desired function. See programming instructions for setting up toggle or maintained operation. VCA control of each input is accomplished by connecting the +5 VDC source to the high side of a

10 K ohm linear

potentiometer, the low side to control/status common ground and the wiper to the desired channel VCA control input.

Programming the ACS-400 Mother board

5

The ACS-400 can be programmed via jumper placement for the following:

1. Toggle or maintained closure of remote control inputs

2. Global mute and dimming assignment

Refer to the Jumper Assignment Pictorial Diagram for the following discussion

Functional description of jumpers:

JP12-17

Toggle/Maintain control of remote control inputs. Place a jumper to the left if maintained closure to ground will hold a command in the desired function. Place a jumper to the right if toggle control is desired. Toggle control is momentary closure for alternate on/off function.

JP19 GRP DIM

– assigns by stereo pair which channels will accept a dim command when remote control dim line is pulled low. Place a jumper in each line where a stereo dim is desired. Place all jumpers for group dim

JP18 GRP MUTE

– assigns by stereo pair which channels will accept a mute command from the remote control group mute control. – This is a separate mute command that can provide a group mute of all channels and is not to be confused with the individual channel mutes which are possible by use of the mute input select jumpers discussed below

JP1B-8B MUTE INPUT SELECT

– allows for remote control input lines to be assigned to mute a specific grouping of channels to be muted. There are four remote mute lines A, B, C, and D. Each can be assigned to command a specific channel to be muted. Simply select which channel will be controlled by which remote control input by placing a jumper in the A, B, C, or D, row as desired on the desired channel jumper.

Note: freight collect shipments will also be refused. When the unit has been received, inspected and tested, the customer will receive a report of the findings along with a quotation for recommended repairs, which are found falling outside of the standard warranty. Units returned for in-warranty repairs which are found not to be defective will be subject to an evaluation and handling charge. In-warranty units will be repaired at no charge and returned via prepaid freight.

Out-of-warranty units needing repair require a purchase order and will be invoiced for parts, labor, and shipping charges.

When ordering replacement part, always specify A) Part number or Description, and Quantity; B) Date of

Purchase, Where Purchased; C) Any Special Shipping Instructions. Always specify a street address, as shipping companies cannot deliver to a postal box.

Broadcast Devices, Inc. is not responsible for any other manufacturer’s warranty on original equipment.

Nor are we responsible for any failure, damage, or loss of property that may occur due to the installation or operation of our equipment outside of recommended specifications.
