INTRODUCTION
Congratulations on purchasing the BAE 1073. The BAE® 1073 was engineered to fulfill the critical need for a high performance audio pre-amplifier/equaliser and is emblematic of the years of experience BAE has had in professional audio. We recommend that you spend a few minutes reviewing this manual to learn about the operation and functionality of your unit.
UNPACKING
Prior to unpacking you BAE 1073, carefully inspect the packing material for any damage. Once you have determined that the packing material has not been compromised, carefully unpack the unit and inspect it for obvious damage. BAE takes great care in designing the packaging to withstand most expected impacts during shipping. If any damage is discovered during the inspection process, contact your BAE dealer so the issue can be immediately addressed.
FEATURES
The BAE 1073 is available as a 10 series module or as a rackmount unit. The BAE 1073 is as authentic as you can get to the original 1073, featuring the same St Ives (Carnhill) transformers as the vintage modules, Elma switches and Canford wire.
The BAE 1073 looks identical to the original vintage module and will happily retrofit in vintage Neve 80 Series consoles because the entire product is engineered in exactly the same way as the originals: The same chassis construction, connectors, printed circuit board layouts, hand-wired looms, and circuitry.
24V PSU
The rackmount version comes with a power supply which is convertible to 230, 240, 100 and 220VAC. The remote power supply includes a four-foot cable capable of four times the current needed by the preamp for optimum sound quality.
Basic Operation
OUTPUT KNOB
The output knob (grey) should be fully clockwise to achieve the highest headroom am cleanest signal path.
ATTENUATE KNOB
Use the Attenuate knob to get in between the 5db steps of the gain knob.
GAIN KNOB
Adjust the Red Gain knob in 5 db increments. The left side is for line and the right side is for mic.
THREE BAND EQUALISER
High Frequency Smooth +/-16dB fixed frequency shelving at 12kHz.
Mid Frequency Smooth +/-18dB peaking, fixed 'Q' with, selectable centre frequencies of 0.36kHz, 0.7kHz, 1.6kHz, 3.2kHz, 4.8kHz & 7.2kHz.
Low Frequency Smooth +/-16dB shelving with selectable frequencies of 35Hz, 60Hz, 110Hz & 220Hz.
HIGH PASS FILTER
High pass filter 18dB per octave slope, switchable between 50Hz, 80Hz, 160Hz & 300Hz.
EQ BUTTON
The EQ button switches the equaliser in or out of circuit.
PHASE BUTTON
The phase button gives 180° phase change at balanced output.

Safety Instructions
 TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.  TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. RISK OF ELECTRIC SHOCK DO NOT OPEN  The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. |
- Read instructions - All the safety and operating instructionsshould be read before operating the unit. The term "unit" hereforth includes the remote power supply.
- Retain instructions - The safety and operating instructionsshould be retained for future reference
- Head Warnings - All warnings pertaining to the unit and powersupply should be adhered to.
- Follow Instructions - All operating and use instructions shouldbe followed.
- Water and Moisture - The unit should not be used near water- for example, near a bathtub, washbowl, kitchen sink, in a wet basement, or near a swimming pool, and the like.
- Ventilation - The unit should be situated so that its location orposition does not interfere with normal ventilation.
- Heat - The unit should be situated away from heat sourcessuch as power amplifiers and power conditioning filters.
- Grounding - Precautions should be taken so that the safetygrounding means are not defeated and the protective earth terminal/safety ground should be connected to a mains outlet with a protective earth/safety ground connection.
- Power Cord Protection - Power supply cords, AC and 5 pinDC, should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs and the point where they exit from the power supply and unit.
- Nonuse Period - The power cord of the appliance shouldFor Service or Repair be unplugged from the AC outlet when left unused for a long period of time.
- Object and Liquid Entry - Care should be taken so thatobjects do not fall and liquids are not spilled into the enclosure through the openings such as the ventilation slots.
