User manual SUMMIT TLA-50

[. . . ] This combination of old and new technology produces an incredibly warm and smooth sounding compression device without the inherent disadvantages of the older designs. Features · · · · · · · · Ease of Operation "Soft Knee" Characteristic Switch Selectable Attack and Release Settings Side Chain Access Stereo Coupling Capability Balanced and Unbalanced Inputs Balanced and Unbalanced Outputs Hand Crafted in the U. S. A. Carefully unpack the TLA-50 and it's power cord. Before powering up the unit, read this manual and observe the cautions for HIGH VOLTAGE. HIGH VOLTAGE · IMPORTANT: Check the back panel to make sure the TLA-50 is configured for the voltage used in your country. [. . . ] The output connector is wired as follows: Pin 1= Ground, Pin 2 = (+) Signal, Pin 3 = (-) Signal. -10 Unbalanced Output Connect the unbalanced output to equipment with unbalanced inputs. 0 VU on the meter corresponds to -10dBm Side Chain Insert The side chain insert jack allows an equalizer to be inserted in order to perform frequency selective compression. A separate signal can also be connected to the tip of the jack in order to duck the signal running through the TLA-50. Model TLA-50 Tube Leveling Amplifier 5 Rear Panel Stereo Link Two TLA-50's can be linked to process stereo signals. When two units are linked in this way, the leveling action will be the same on both units. The TLA-50 providing the most compression will always control the other unit. To "stereo link" two units: 1. Set the BYPASS switch on the front panel to LINK. Balanced Input The dual purpose input jack accepts XLR plugs for balanced inputs and standard 1/4" plugs for unbalanced inputs. Maximum signal input level is +26dBm. 6 Summit Audio, Inc. Basic Operation Important: For proper operation of the TLA-50 (or any vacuum tube device for that matter), allow the unit to warm up with power on for 15 minutes before use. Four Easy Steps 1. 4. Set the Gain Reduction control to 0 and adjust the Gain control for 0 VU on the meter. Adjust for the desired amount of gain reduction and recheck the output level. Try different attack and release settings, depending upon the program. No Gain Reduction Important: Do not block the cooling holes and allow adequate ventilation. OUTPUT LEVEL INPUT LEVEL As the amount of gain reduction is increased, the processed audio follows a smooth reduction curve, thereby changing the compression ratio. If a large peak is detected, the unit will automatically increase the compression ratio to keep the audio output controlled. Model TLA-50 Tube Leveling Amplifier 7 Applications Applications Tracking, Live Sound Mixing Plug the TLA-50 into the insert jack or patch bay of your mixing console. If you're using an external microphone preamplifier, connect the TLA-50 directly after the preamp.
