Introduction Thank you for purchasing the Servo Series Power Amplifier from Samson Audio! We know you don’t like reading owners manuals, but you’ve just purchased one of the finest sound reinforcement power amplifiers around, and we want to tell you about it. So, before you plug in, we’d like to suggest you take just a few moments out to scan these pages. We’ll make it as painless as possible, we promise—and, who knows, you might just pick up a tip or two.
Servo Series Features ������ ��������� ����� The Samson Servo Series power amplifier utilizes the latest technology in professional power amplifier design. Here are some of its main features: • Power to spare - Each amplifier delivers the following power ratings.
Guided Tour - Front Panel � � � � � � � ������ ��������� ����� � � � � � � 1: Fan Vent - The Servo Series amplifiers stay cool thanks to their twin, forced-air cooling tunnels. Cool air is drawn through the front panel fan vents, reducing the temperature of the internal components while forcing the heat out the rear vents. The fans will actually sense the internal temperature and adjust their speed to maintain the optimum cooling conditions.
Guided Tour - Rear Panel � � � � � � � � � � � � 1: RCA Input connectors – You can connect unbalanced incoming signals to the Servo series using the RCA connectors, which are wired as follows: Pin 2 (or Tip) hot, and Pin 1 (or Sleeve) ground. The Servo Series accepts input levels of any strength but needs at least -10dBV dBu to achieve maximum power.
Setting Up and Using Your Servo Series Setting up your Servo Series is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed—it can be used free-standing or mounted in a standard 19” rack, requiring only two rack spaces.
The Servo Series Protection Circuitry As noted in the “Guided Tour” section of this manual, the Servo Series front-panel Protection LED indicates the activity of the relay speaker connection circuitry. When the Protection LED is lit, this circuitry is active, and all connected speakers are muted (provided with no signal), thus protecting them and preventing any audible “thump” from occurring.
Bridge Mode The Servo Series provides a rear-panel switch that allows it to be used in either Stereo or Bridge mode. When this switch is placed in the “STEREO” (down) position, the Servo Series functions as a true stereo amplifier, where both of the two independent amplifier channels (Channel 1 and Channel 2) can receive different input signals and produce independent output signals.
Servo Series Connections The illustrations on this page show the required interconnections when using the Servo Series in Stereo and Bridged modes.
