2 channel Amplifier

LDS 2-150B

The LDS 2-150B audio/video amplifier is an innovative, attractive and versatile performer that can be used as a television amp as well as an audio amplifier where its diminutive size can satisfy the needs of a custom solution.

Housed in a slim 1U chassis with an elegant blue LED, the LDS 2-150B 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 2-150B 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.

The LDS 2-150B incorporates a CPU that measures an intended impedance to prevent an excessive load being imposed that could cause overheating.

The front panel allows input selection: switch-off delay time, a separate “B” mode trigger level adjustment and a volume setting. The rear panel includes two sets of line level inputs, two sets of speaker level inputs, a set of buffered outputs, 12-volt trigger and music signal sensing circuits. In addition there is an adjustable turn on control, two sets of removable speaker connectors, the Sherbourn patented LDS speaker test circuit and an 18 dB per octave sub-sonic filter to prevent low frequency saturation of transformer volume controls.

Optional rack mounting hardware is available for those who choose to include the amp in a custom application.

Features

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

Dealer Feedback

"... That was my argument. Your amps really do sound better, test more easily, weigh a bit less, run cooler, cost less and look great. What else can we ask for?"
