Frequently Asked Questions - SC 64 DBX

How do I connect the SC 64 to my audio system?

Use balanced XLR or TRS cables. Connect inputs to your source and outputs to your amp or mixer. Ensure all devices are powered off during connections.

What are the typical applications for the SC 64?

It is used for compression and limiting in live sound, studio recording, and broadcast to control dynamic range.

How do I adjust the threshold setting?

Turn the Threshold knob clockwise to increase the level at which compression begins. Start at 0 dB and adjust while listening to the effect.

What is the bypass function?

Pressing the Bypass button removes the SC 64 from the signal path, allowing comparison between processed and unprocessed audio.

Can I use the SC 64 with unbalanced gear?

Yes, use TRS cables for unbalanced connections. For best performance, keep cable lengths short to avoid noise.

How do I clean the device?

Disconnect power and wipe the front panel with a soft, dry cloth. Do not use solvents or abrasive cleaners.

What warranty does the SC 64 come with?

DBX offers a limited 1-year warranty covering defects in materials and workmanship. Register online for details.

Can I rackmount the SC 64?

Yes, it fits a standard 19-inch rack (1U). Use the included rack ears to mount securely.

What does the Link function do?

When using two units in stereo, the Link mode couples the gain reduction for both channels, maintaining stereo balance.

Does the SC 64 support digital audio?

No, it is an analog processor with balanced analog inputs and outputs. For digital systems, use an AD/DA converter.

IMPORTANT SAFETY INFORMATION

The symbols shown above are internationally accepted symbols that warn of potential hazards with electrical products. The lightning flash with arrowpoint in an equilateral triangle means that there are dangerous voltages present within the unit. The exclamation point in an equilateral triangle indicates that it is necessary for the user to refer to the owner's manual.

These symbols warn that there are no user serviceable parts inside the unit. Do not open the unit. Do not attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any reason will void the manufacturer's warranty. Do not get the unit wet. If liquid is spilled on the unit, shut it off immediately and take it to a dealer for service. Disconnect the unit during storms to prevent damage.

SAFETY INSTRUCTIONS

NOTICE FOR CUSTOMERS IF YOUR UNIT IS EQUIPPED WITH A POWER CORD.

WARNING: THIS APPLIANCE SHALL BE CONNECTED TO A MAINS SOCKET OUTLET WITH A PROTECTIVE EARTHING CONNECTION.

The cores in the mains lead are coloured in accordance with the following code:

GREEN and YELLOW - Earth

BLUE - Neutral

Section 3 - Wiring

3.1 SC 32 and SC 64 Wiring

Audio Cable Wiring

All audio and control connections to the SC 64/32 are via 12 terminal female Phoenix Combicon-style 3.5mm connectors, which are supplied for making these connections.

Audio Input and Output wiring convention

Balanced wiring - The convention for balanced wiring (2-wire plus shield) is:

Unbalanced wiring - The convention for unbalanced wiring to the inputs (1-wire plus shield) is:

Control Inputs

Used to connect switches. There are two common (ground) connections, labeled "C" to the left of the eight CONTROL INPUTS, and two software assignable reference voltage outputs, labeled "R" to the right of the eight CONTROL INPUTS.

Relay Contacts

Supports control of a voltage source and load that is AC, or supports control of a voltage source and load that is higher-current DC than is supported by the logic outputs. A normally open circuit or a normally closed circuit is available.

OPTO Output

In addition to the six standard logic outputs, there is an isolated output, which fails safe (open circuit) if the unit becomes faulty.

OPTO Output

Logic Outputs

Used to connect 'tally' indicator LED's or relays. There are six standard LOGIC OUTPUTS which produce 0V or +5V DC via an internal 440 Ohm resistor and one internally connected common (ground) connection C. Each logic output pin can sink up to 60mA.

An LED connected between one output (Anode, A) and common (Cathode, K) will illuminate when the logic output is activated, without requiring any external current limiting resistor. A high sensitivity relay (such as a reed relay) may be driven by connecting four outputs in parallel. This arrangement will develop 4V across a 500-Ohm coil, providing that all four outputs are made logic 1 simultaneously.

Logic Outputs

3.2 Zone Controller Wiring and Installation

Zone Controller Wiring

All Zone Controllers can be wired serially or in parallel. To wire in series, each Zone Controller must have an identification number (ID) chosen using the DIP switches on the side of the controller (see diagram A). A single Zone Controller can be used to control multiple outputs. Conversely, multiple Zone Controllers can be used to control a single zone (for example, a ZC1 and a ZC3 controlling volume and source in a single zone respectively). In every case, each Zone Controller is given a unique ID.

To wire the Zone Controllers in parallel, a ZC-BOB must be used. Each Zone Controller must have a unique identification or number chosen using the DIP switches on the side of the controller (see diagram A). To wire in parallel, each controller must be wired into a port of the ZC-BOB with a connecting wire going to the SC device (see diagram C).

ZC ID (1-6) ZC ID (7-12) DIP Switch Setting
1	7
2	8	ON
3	9	ON
4 10		ON
5 11		ON
6 12		ON

To set up the Zone Controllers, the System Architect GUI must be used. Open the GUI and click on Card Configuration within the Hardware Configuration section of the Tools menu. In this window, Zone Controllers are assigned to ZC Inputs 1-12. The input numbers on the left side of the window correspond to the ID number set using the DIP switches on the individual Zone Controllers. To select ID#2 for example, simply flip the 2 switch into the on position. ID 1-6 are connected to the top ZC input on the rear panel and ID 7-12 are connected to the bottom input. To create ID 7-12, add 6 to the ID # selected on the back of the ZC. For example, to get an ID# of 10, connect to the bottom ZC Input (7-12) and set the ID# to 4.

Zone Controller Installation

The installation of the Zone Controllers MUST be accomplished with the use of cable which is rated VW-1 or higher. Common NEC designations which meet this rating include: CMP, CMR, CMG, CM and CMX.

ZC-1 - The ZC-1 is a programmable zone controller that allows input or output volume level control from a wall panel.

ZC-2 - The ZC-2 is a programmable zone controller that allows input or output volume level and mute control from a wall panel.

ZC-3 - The ZC-3 allows wall panel routing and Actions selection for the SC devices.

ZC-4 - The ZC-4 provides contact closure routing and Actions selection for room combining or fire safety applications.

ZC-Fire - The ZC-Fire is the interface to generic fire alarm relays. When fire alarm activates, the general purpose relay can typically be programmed to close if normally open or vices-versa. The ZC-fire interface unit monitors the state of the relay (n.o. or n.c.) and upon the state of change, notifies the SC 32/64, which then mutes its outputs.

ZC-6 - The ZC-6 is a push-button up and down input or output volume controller.

ZC-7 - The ZC-7 allows Actions selection for the SC devices.

ZC-8 - The ZC-8 is used for a combination of input or output volume up/down, and four position source/program select.

ZC-9 - The ZC-9 allows wall panel routing and Actions selection for the SC devices.

ZC-BOB - The ZC-BOB allows parallel or home run cabling of the Zone Controllers.

dbx ^® incorporates high quality mechanical fans in some products. All mechanical fans have a limited life expectancy. We recommend annual inspection of fans for dust occlusion and excessive noise. Fan assemblies should be replaced after six to ten years of use. Environmental factors such as elevated temperature, dust, and smoke can adversely affect fan life. Systems exposed to these conditions should be inspected more frequently. Fan replacement can be performed either at the factory or by an experienced technician in the field. Please contact dbx Technical Support for more information on purchasing replacement parts or product service.

dbx has a policy of continued product improvement and accordingly reserves the right to change features and specifications without prior notice.
