2 channel Amplifier
 The LDS 2-75B is identical to the LDS 2-150B but we have eliminated the extensive A/V switching capability for those who are looking to utilize the exceptional performance but don’t need that advanced capability of the LDS 2-150B.
Housed in a slim 1U chassis with an elegant blue LED, the LDS 2-75B can be freestanding, wall mounted or rack mounted using the optional panel. This “discrete” amplifier uses a hefty toroidal transformer and outputs two channels of 50/75 watts into 8/4 ohms respectively. Used in its mono mode, the LDS 2-75B outputs up to 150 watts. Its outstanding musical performance is ensured by its skillful design and the use of top quality components including bi-polar and MOSFET transistors.
Optional rack mounting hardware is available for those who choose to include the amp in a custom application.
Features
- Elegant standard width chassis that can be free standing, wall-mounted or rack-mounted
- Discrete output devices and a large toroidal transformer for a clean total output of 50/75 watts into 8/4 ohms respectively
- Front panel includes control input selection, a delay time control, a separate B mode trigger adjustment and a concentric volume setting control for both A and B zones
- Rear panel includes two sets of line level and speaker level inputs, a set of buffered outputs, a 12 volt trigger, a music signal sensing control, an adjustable turn-on control and two sets of removable speaker connectors
- 18dB per octave sub-sonic filter to prevent low frequency saturation of transformer type volume controls
- Patent Pending circuitry that will automatically check for short circuits and then measure the impedance of the intended speaker load before connecting it to the amplifier. This test of impedance helps to ensure that the load is within the required specification and so will not cause excessive distortion, overheating or long-term reliability problems
- Will drive two pairs of eight ohm or one pair of four ohm loudspeakers and is three ohm stable
- Can be rack mounted using an optional full width panel
- Model LDS 2/75B is identical to the LDS 2/150B except that is has no audio/video switching circuitry
