CONTROL A FUNCTIONS LED E When the LED is lighted the Amp 1 is “ON”, receiving power from the power supply. B PREAMPLIFIE R I NPUT This input accepts RCA input connections from an external preamp or crossover; connect left channel to left channel and right channel to right channel. ON- OF F BUTTO N When in the ON position (button depressed), high voltage power is received by the Amp 1 circuitry from the power source.
SETTING UP The Amp 1 comes with seven (7) tubes, as follows: 12 AX7 (V2) FIRST S TAG E AMPL IF ICATION TUBE The first stage of amplification in the amplifier section of the Amp 1 is achieved through the use of this dual triode, amplifying both channels, one per triode section. The 12AX7 may be replaced with the ECC83 or 7025A tube. 12 AU7 (V1 & V3) D RIVE R TUBES These tubes split the phase of the signal and drive the push/pull pairs of power tubes.
INSERTION OF THE TUBES 1. Using the screwdriver supplied, remove the cover of the Amp 1. For your convenience, only two of the screws are installed at the factory. 2. When handling the tubes, it is recommended that the cotton gloves provided be worn to prevent skin oils from depositing on the glass surface and possibly causing the tube to become prematurely “gassy”, thereby shortening the tube’s useful operating life. 3.
TROUBLESHOOTING If at any time the Amp 1 fails to work properly, consult this checklist: 1. Check that the AC Detachable Power Cord is plugged into the Amp 1 Detachable Power Cord Socket (C) and is connected to a live source of AC power. For instance, if using a power bar, check that the bar is turned on. 4. Be sure the rest of the system is functioning properly (i.e. source unit, power amplifiers, cables and connections, etc.). 5.
BREAK -IN T IME PACKING MAT E R I A L S As with all audio electronic products, the ultimate sonic character of the Amp 1 will not be realized until and unless the unit receives a minimum of approximately 70 hours of signal break-in time (i.e. the Amp 1 is on and outputting a signal). Please retain all of the packing material and shipping boxes for your Amp 1. They are custom designed to prevent shipping damage from occurring. Sonic Frontiers, Inc.
4. Sonic Frontiers, Inc. shall not be responsible in any way for consequential or indirect damages or liabilities resulting from the use and operation of the product covered herein or resulting from any breach of this warranty or any implied warranty relating to said product. During this period, Sonic Frontiers, Inc. will repair or replace any defective components free of charge. A Return Authorization Number (RA Number) is required before any product is returned to our factory for any reason.
BIAS ADJUSTMENT WARNING: Hazardous and potentially lethal voltages! The Bias adjustment procedure described below involves working with equipment covers off and power applied, exposing the operator to potentially hazardous or lethal voltages. These tests and adjustments should be performed only by qualified personnel with the proper testing equipment and training. The Anthem AMP 1 has been designed to give many hours of listening pleasure and should only require biasing at tube replacement time.
