INTRODUCTION

Thank you for purchasing the ART SCC Studio Control Center. The SCC is the easy way to reduce the clutter of wires in your project studio and provide a single knob to quickly control the volume on your studio monitors.

The SCC allows you to quickly select or mix up to three input sources. After you control the volume of the input selected, you can enable one to three outputs. A separate headphone monitor section allows you to monitor either the input selection or a fourth (cue) input that normally goes to the studio feed. Level trims on inputs and outputs let you switch between different sources or outputs without jumps in level, allowing you accurate comparisons between different monitors or sources.

The outputs, as well as two of the inputs, are balanced and support low noise performance. Two of the inputs (IN3 and Cue) are stereo inputs, typically driven by headphone outputs (Phone, iPad, etc.).

Although it is very reliable and easy to use, we ask that you take a moment to read the manual to get the best performance.

Block Diagram

FRONT CONTROLS

Front panel controls

INPUT MIX switches

The INPUT MIX switches are push ON, push OFF. The switch caps light green when depressed (ON).

Note: you can trim the input signal levels individually to prevent level jumps between individual selections. Refer to the section "INPUT and OUTPUT Trims" for more information on this.

OUTPUT SELECT switches

The OUTPUT SELECT switches are push ON, push OFF. They light green when active. All outputs can be trimmed to optimize each output for its respective power amp sensitivity. Refer to the section "INPUT and OUTPUT Trims" for more information on this.

MONO switch

Depressing the MONO switch will sum the left and right channels of the input mix signal. This function is useful when auditioning a signal that may be listened to with a mono output device. NOTE: the MONO function does not affect the INPUT MIX signal sent to the headphone section.

OUTPUT MUTE switch

You can mute ALL of the outputs using the OUTPUT MUTE switch. This is useful when you need to reduce the audio level but want to quickly return to the previous volume level and speaker selection.

INPUT LEVEL meter

The INPUT LEVEL meter monitors the input mixer. This is used for ensuring a signal is present and trimmed to the correct level.

HEADPHONE SOURCE switch

This switch selects the input mix signal (when depressed) or the Cue input. This provides a way to monitor the signal usually sent to the control room (input mix) or the studio or recording musicians (Cue).

HEADPHONE LEVEL control

The HEADPHONE LEVEL control allows you to adjust the signal level at the headphone jack. You can completely mute the headphone audio by turning the control fully CCW.

MASTER LEVEL control

The large knob adjusts the output level of the signal present at OUT1, OUT2 and OUT3 only.

REAR PANEL

Rear Panel jacks

Rear panel jacks

The rear audio jacks on the SCC are all 1/4" TRS balanced (tip=+, ring = -, sleeve = gnd) except where noted.

IN1 and IN2 jacks

Inputs 1 and 2 are TRS balanced line inputs. These inputs can be individually trimmed for level over a 24dB range.

IN3 jack

Input 3 is a TRS unbalanced stereo line inputs. IN 3 can be connected to a headphone output or any other stereo line level source. This input can be trimmed for level over a 24dB range.

CUE IN jack

The CUE IN is a TRS unbalanced stereo line inputs. IN 3 can be connected to a headphone output or any other stereo line level source.

OUT1-OUT3 jacks

The output jacks of the SCC are TRS impedance balanced outputs with a 200 Ohm source impedance. They can be connected to either balanced or unbalanced inputs. You need to carefully adjust the output trims to guarantee the correct output levels for your device. Refer to the section "INPUT and OUTPUT Trims" for more information on trimming these outputs.

POWER switch

The POWER switch lights red when depressed and the correct power supply is present. The SCC has power up/down muting that monitors the power supply to minimize pops on power loss. It is recommended to power down power amps and powered monitors before powering down the SCC to prevent speaker damage.

POWER jack

The SCC is powered by an external 9 VAC/1000mA power supply to minimize noise and heat inside the unit. Use the power supply that came with the unit for the best performance.

INPUT and OUTPUT TRIMS

Bottom view - trimmers

LEVEL TRIMS

The Input trims are located on the bottom of the unit. Use a small flat blade screwdriver with a tip that is less than 1/4" wide to adjust each trimmer. Turning the trimmer clockwise (as you view the bottom of the unit) increases the gain.

The trimmers are easily accessed when the unit is on its side, allowing you to monitor the level meter while making adjustments.

INPUT TRIMS

Adjust each input trim by applying a signal to the corresponding input jack as you monitor the input level meter. Adjust the trimmer such that the Red LEDs light occasionally on the highest levels. After the initial adjustment, switch between the inputs and make sure that there are not big differences between different inputs. If differences exist, reduce the louder input's trimmer.

OUTPUT TRIMS

Ideally, the output trims should be set as high as possible to minimize noise. Most power amps allow this through the use of input level controls. A good starting point for the level controls of the power amp would be centered. This will probably change the sensitivity of the power amp by about 12-15 dB. If your amp has a 0.5V sensitivity spec, this level setting would increase it to 2.0V to 2.8V.

When the output trimmer is fully CCW, the maximum output level is 0.5V, when centered it is about 2.2V and when fully CW it is about 8V. If you are not sure what the sensitivity of your amp is, start with the SCC's output trimmer in the center.

To adjust the output trims, set the Master Level Control to 12 O'clock or lower to make sure that excessive levels are not preset. You can increase this later if required.

1) Enable the first output and set the first output trimmer based on either your amp's input sensitivity or set the SCC output trim to the center.
2) Compare this level to the next power amp/powered speaker and increase the lower of the outputs by turning its trimmer CW. If a trimmer is fully clockwise and its output is still not loud enough, you can reduce the other channel's output via its trimmer until the two channels are equal.
3) Repeat this for the third output if necessary.

APPLICATIONS

Typical setup

The SCC is designed to be used in a project studio. It interfaces between a recording interface and multiple monitors and headphones.

IN1 and IN2 connect to balanced or unbalanced line level outputs from the recording interface. IN3 interfaces with headphone outputs (Phones/ iPad, etc.) The CUE input connects to the recording interface headphone output you intend to use as a studio feed for recording musicians.

Note: When using headphone outputs as a source, make sure that the output level of the source is set to its maximum level for best results.

The SCC outputs connect to power amps or powered speakers. While they support balanced or unbalanced connections, we strongly suggest using balanced cables for the best performance. It is also helpful to turn down the level controls on power amps (and turn up the output trims on the SCC) to minimize the noise the cables could pick up.

Headphone output use

The front panel headphone output can be applied in a number of ways.

In a recording/tracking application it is used as an output to the musicians. The HEADPHONE SOURCE switch selects between a monitor mix for the musician (CUE input) or a playback mix (INPUT MIX).

It can also be used strictly in the control room for monitoring/mastering the session when speakers are not required. This frees up your recording interface headphone out for dedicated studio use.

Mastering

The SCC is the ideal tool for mastering. Once the different speakers are trimmed for level differences, you get ideal comparisons. You can even listen to multiple monitors simultaneously. This feature allows one of the outputs to be connected to a sub-woofer. Using this allows you to check the sound with and without a sub-woofer, possibly simulating typical car response.

The MONO switch is also a mastering tool useful in checking how your material will sound when not played in stereo.
