- Page 2 About About Boulder Amplifiers, Inc. Boulder was founded in 1984 and is the last high-performance audio manufacturer operating in North America to still perform all of its own design, engineering and manufacturing in-house. While this form of production may be more costly than outsourcing, the resulting quality control and reliability of the finished products are never compromised.
- Page 3 Please take a few minutes to read through this instruction manual prior to using your 1110. This will help you understand the many functions and capabilities of the preamplifier. It will also allow you to maximize the convenience and performance for which it was engineered.

- Page 8 Getting Started Introduction The 1110 Preamplifier embodies years of development and is one of the most advanced preamplifiers available. Here are some of the features that set the 1110 apart from the competition: Analog features: • Proprietary, fully-balanced Boulder volume control •...
- Page 9 Preamplifier weighs 35 lbs. (16 kg). If possible, two people should unpack and place it into position. Be sure to save all packing materials! The 1110 is shipped in a foam wrap to protect the preamplifier’s fine finish. Try not to damage this wrap in the event that the unit must be transported elsewhere in the future.
- Page 10 Getting Started How to Clean the Casework If the 1110 must be cleaned, use only a soft, lint-free cloth moistened with plain water. Never use any type of chemical cleaner unless recommended by your dealer or the Boulder factory. Do not use bleach! Bleach will remove the anodized surface of the case- work.
- Page 11 This is necessary for the IR remote control to function properly. Because it is heavy, the 1110 system must be placed on a sturdy, stable surface. Do not place in an enclosed rack without ventilation. The 1110 must have at least 3 inches (8 cm) of airspace around the chassis for proper cooling and airflow.
- Page 12 Connect each source to one of the five inputs provided on the rear panel of the 1110. Later, you will be able to program each input with the source’s name (see HTML Programming: Setup on page 4-11), so you may want to...
- Page 13 It converts a balanced input into a RCA phono input at the rear of the 1110. Like the above cable, the negative input of the 1110 is connected to the ground of the RCA phono. However, this negative side will then share the shield wire with the chassis ground and will not have the best hum rejection.
- Page 14 The Ethernet connections are for Internet access in order to program input names or download software updates for the 1110. One of the Ethernet jacks should be connected to a network with an active Internet feed. Because they are switched, it does not matter which jack is used.
- Page 15 (input) cables. With the low output impedance of the 1110, distances of more than 50 me- ters between preamplifier and power amplifier are practical.
- Page 16 Polarity Please note that the 1110 Preamplifier conforms to the standard of Pin 2 as high or “hot” for all analog balanced inputs and outputs. Because input and output polarities are handled through the Setup menu and the remote...
