Controls & Connectors 7 Front Panel The Synergy Series differ only slightly across all models and all share the same features on their front panels. Figure 1 shows the panel layout of three Synergy amplifiers, SY4200, SY1200 & SY6125. The SY1200 looks the same as the SY400, SY800, SY1600, SY400V & SY800V. The functions of the controls and indicators are as follows: 3 Overload Indicator 1 Attenuator Level control for your amplifier is provided by a potentiometer on the front panel and indicates gain.
Controls & Connectors NOTE: You should always ensure that the fan grille is kept clean and free from the build up of dust and lint. This will ensure longer operation of your amplifier and reduce the possibility of it prematurely going into thermal shutdown mode. See the section “Installation - Cooling “ on page 14 for recommended cooling procedures. 6 On Indicator This LED will illuminate blue and indicates that the amplifier is on and receiving mains power.

Controls & Connectors 11 Rear Panel 8 Balanced Input A female 3-pin XLR type connector is provided on each input: Pin 1 = Signal Ground; Pin 2 = Hot (non-inverting or in phase); Pin 3 = Cold (inverting or reverse phase). 8a Signal Strapping A male 3-pin XLR type connector is provided (not on SY6125) and wired in parallel with the female input XLR for strapping / looping signal between amplifiers.
Controls & Connectors attenuator. The output from channel B will automatically be of the opposite polarity (reversed phase) and speaker termination should be sourced from the red binding-post outputs. Alternatively, the speaker could be connected to poles 1+ & 2+ of the 4 pole speaker connector (see Installation - Output Wiring on page 11). The SY400V & SY800V cannot be bridged. The SY6125 allows bridging of channels B & C and channels D & E. The bridge switch is located on the rear panel.

Installation 3. Installation fans to evacuate the heated air and aid the flow of cool air through the unit. Power Requirements Input Wiring Power consumption for your model of the Synergy Series amplifier is indicated on the rear panel for maximum output. IMPORTANT Do not directly connect pin 1 on the amplifier’s input or strapping XLR, to the amplifier’s chassis, speaker ground or power ground! Ensure that your mains voltage is the same as the rear panel mains voltage marker (+/- 10%).
Installation 15 Binding Post Outputs When terminating to the 4 mm binding post (banana jack) output connectors, banana plugs or bare wires can be used. The red terminal is positive and the black terminal is negative (ground). If running in BRIDGE mode, only the red binding posts are used. For the SY400, SY800, SY1200, SY1600: When bridging, Channel A provides the positive output to the load and channel B provides the negative output to the load.
Operation 4. Operation IMPORTANT All signal source equipment should be adequately earthed. This not only ensures your safety but everybody else's as well. Faults can and do occur in mains connected equipment where the chassis can become “live” if it is not properly earthed. In these instances, the fault in a “floating” (ungrounded) piece of equipment will look for the shortest path to ground, which could possibly be your amplifier's input.
Operation 17 of 600 Ohms or lower to avoid unwanted high frequency loss in the cabling. Input overload occurs at +20.5dBu (8.25 volts). Hum Problems Most equipment is designed for minimum hum when used under ideal conditions. When connected to other equipment, and to a safety earth in an electrically noisy environment, problems may occur.
Maintenance 5. Maintenance Only competent or qualified persons should attempt any service or maintenance of your amplifier. Your Synergy Series amplifier will need minimal maintenance. No internal adjustments need to be made to the unit to maintain optimum performance. To provide years of unhindered operation we suggest a maintenance inspection be carried out on a regular basis, say every 12 months or so.
