1. LED Power Indicator – The LED illuminates when the unit is turned on.
2. REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when
+12V DC is applied.
3. Power Terminals – The power and ground connectors on the amplifier are gold-plated and will
accommodate up to 8 AWG wire maximizing the input current capability of the amplifier.
4. Speaker Terminals – The heavy duty, gold-plated terminal block connectors (+ and –) will
accept wire sizes from 8 AWG to 18 AWG. These gold-plated connectors are immune to
corrosion that can cause signal deterioration.
5. Cast Aluminum Heatsink – The cast aluminum heatsink of the Power amplifier dissipates heat
generated by the amplifier's circuitry. The inherent advantage of casting provides a 30%
improvement of cooling over conventional extrusion heatsink designs.
6. Gain Control – The input gain control is preset to match the output of most source units. It can
be adjusted to match output levels from a variety of source units.
7. Internal Crossover (Models 300X & 500X) – Is a built-in 24dB/octave Butterworth filter
selectable between 120Hz High-Pass (HP), All Pass (AP), or 80Hz Low-Pass (LP) operation.
