REMOTE ON/OFF CONTROL (optional)

Some 2B-LP models come equipped with a remote on/off control feature. This feature allows the amplifier to be turned on and off by application of a control voltage of 12V (AC or DC) at 5mA. The control voltage is connected via the dual spring loaded terminal block located beside the “Remote/Local” toggle switch. To insert wires press a small (1/8”wide maximum) blade screwdriver into the small rectangular orange slotted levers located at the top of the terminal blocks. While pressing in against the lever, insert the control voltage wires into the circular openings, then release the lever. The terminal blocks can accept stranded wire gauges between 18 to 26 AWG. To bypass the remote on/off control, place the toggle switch in the “LOCAL” position. To turn the power amplifier off, place the toggle switch in the centre position. Only when the toggle switch is in the “REMOTE” position will the 2B re- spond to a remote control voltage. Please note that some 2B-LP models may contain a mechanical push-button power switch located on the front panel. This mechanical power switch is in series with the remote electronic power switch, and must therefore be in the ON (pressed in) position to enable the amplifier. If the front power switch is in the OFF (out) position, then the amplifier will be off regardless of the position of the rear mounted “Remote ON/OFF” switch or the presence or absence of a dc control voltage. The control voltage must be 12V at 5mA, but it can be either AC or DC due to an internal rectifier circuit. If a DC control voltage is used, it does not matter which terminal is connected to positive and which is connected to negative.

CSA ADVISORY:

This amplifier will deliver full undistorted power at 4 ohms without current limiting and will deliver a dynamic musical signal to a 4 ohm load without overheating. However, Canadian Standards Association (CSA) procedures call for testing at 33.3% of full measured undistorted power into 4 ohms continuously which is an extreme condition insofar as internal amplifier heat dissipation and causes cycling on the heat-sink-mounted thermal circuit breakers. CSA testing procedures call for these thermal breakers to be artificially bypassed whereupon an additional resetting thermal protection mechanism, internal to the power transformers, will come into play and will cycle to protect the amplifier from damage. CSA does not consider this “normal operation”, however, and therefore consid- ers this model “unacceptable” for 4 ohms loading.
