Integrated Amplifier

Integrated amps are the most common piece of electronics in the stereos we all grew up with. An Integrated Amplifier is about keeping things simple by combining the pre-amplifier (or the first stage of amplification), with the Power Amplifier (where the heavy lifting occurs in a system). 

This has a lot of advantages including:

• the reduction of cost in manufacturing (One Chassis for two components!)
• delivery of a curated pairing of components (Pre-amp & Power Amp) that do not require costly cables to hook them up. 
• Smaller footprint, allowing a great system to fit nicely in any room.

LTA has devoted themselves to the goal of delivering Hi-Fidelity to more people, so developing their great products into integrated designs is a natural path we have been excited to be a part of!

Input / Output

• Inputs: 4 single-ended Cardas RCA stereo, 1 true balanced stereo input using two 3-pin XLRs

• Speaker Output: 4 copper speaker binding posts, banana or spade

• Headphone Output: Low: Approx. 1 watt per channel, High: Approx. 2 watts per channel

• Tape Monitor: 1 stereo tape monitor out, 1 stereo tape monitor in - both Cardas RCA           

• Home Theater Function can select any input for fixed volume

User Experience & Interface

• Front Panel Controls: 7 brass touch switches (power, input, tape monitor, up, down, menu/select, back), volume control, and headphone speaker switch

• Remote Control: All front panel functions using paired Apple TV Remote (power on programmable)

• Volume Control: 100 stepped attenuator (smallest step 1/1000th of total value) using Vishay Dale 1% precision resistors.                                                                          

• Display: 16 Levels of brightness and programmable 7-second time out
