REL Acoustics Limited REL Stadium III Self-Powered Sub-Woofer System [Expired]


no longer for sale

This listing is an estate sale for the widow of a fellow audiophile that has passed away. The sub-woofer was purchased new in 2001. Other items will be listed as the listings are prepared when time permits. Local pick-up is preferred, but the out-of-state buyer is certainly welcome we'll make arrangements for shipping and coordinate from this end. REL sub-woofer amplifiers are fully DC coupled to avoid phase shifts and compromises in their low end performance. The line level and filter stages are fully regulated to ensure total isolation from the power amp stages. The filter stages are unique designs using the highest quality components. The capacitors are high quality nitrogen filled polystyrene types of 1% very close tolerance and an indefinite life. The use of very close tolerance components also ensures consistency of performance throughout the production life of each model. Great care is taken over the star-ground system to maximize sound quality. There is further filtering of the higher frequencies to ensure optimum performance at all settings. The built-in power amplifier is built onto a separate circuit board and uses ultra rugged audio grade MOSFET output devices. The power supply is the engine house of the amplifier, the smoothing capacitors are long life with very low equivalent series resistance (ESR), the bridge rectifier is very conservatively rated at 35 Amps. The transformers are ultra quiet audio quality low loss these are especially manufactured to REL’s strict specifications. REL products are known for ruggedness in service. This ensures an exceptionally robust, long lasting device. For all practical purposes they claim it will probably outlast its owner! CONTROLS AND CONNECTIONS MODE SWITCH. Used to set phase* and to bypass crossover for Low Level input**. Position 1 / Line: 0 degrees phase, crossover engaged low level input Position 2 / LFE: 0 degrees phase, crossover bypassed for low level input Position 3 / Line: 180 degrees phase, crossover engaged for low level input Position 4 / LFE: 180 degrees phase, crossover bypassed for low level input *Phase selection affects both Hi and Lo level inputs **Crossover is always engaged for Hi level input regardless of mode switch position. LO LEVEL input volume control. Adjust for output level when using LO LEVEL RCA phono input or balanced line level input XLR socket. HI LEVEL input volume control. Adjust for output level when using HI INPUT Neutrik socket or BAL HI INPUT Neutrik socket. FINE ROLL OFF control. Fine adjustment of roll-off point, used in conjunction with Coarse Roll Off control (below). The owner’s manual has a chart for crossover frequencies determined by setting combinations of both controls. COARSE ROLL OFF control. Coarse adjustment of roll-off point, used in conjunction with Fine Roll Off control (above). The owners’ manual has a chart for crossover frequencies determined by setting combinations of both controls. OdB LO INPUT RCA phono socket. Used to connect the Sub Bass System at low level to the sub/LFE output of the amplifier/processor or left and right pre-amp outputs. If Lo Level inputs are used to connect pre-amp right and left outputs then a 12dB attenuator is available from REL to balance the two inputs. Alternatively, a high quality Y-adaptor may be employed to connect at either input as system gain characteristics demand. +12dB LO INPUT RCA phono socket . As OdB LO INPUT but a higher sensitively. If LO LEVEL inputs are used and connected to pre-amp right and left outputs then a 12 dB attenuator is available from REL to balance the two inputs. Alternatively, a high quality Y-adaptor may be employed to connect at either input as system gain characteristics demand. BAL HI INPUT Neutrik Speakon socket. Used to connect the Sub Bass System at high level to the speaker output of one channel of a differential output or bridged to mono amplifier. UNBAL HI INPUT Neutrik Speakon socket. Used to connect the Sub Bass System at high level to the main speaker output of amplifiers. BAL LO INPUT XLR socket. Used to connect the Sub Bass System at low level to preamplifier balanced line outputs.
