User manual SUMMIT TLA-50

[. . . ] As with the Attack Switch, there are three settings: Fast, Medium and Slow. The release time setting is also controlled by the program material. The slower the release time setting, the more the program material determines and the release time. Meter Switch This control switches the front panel meter to monitor either the output level or the amount of gain reduction taking place. Gain This control sets the overall gain of the TLA-50. [. . . ] The TLA-50 providing the most compression will always control the other unit. To "stereo link" two units: 1. 3. Connect a standard 1/4" cable between the two units. Set the controls on both units the same. 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. Switch the attack to slow and the release to fast. 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.
