MODE SWITCH OPERATION

LIMITER

A limiter is a circuit that prevents signal overload and distortion in an audio signal path. When engaged, the internal limiter circuit will keep the audio signal from going over a preset level threshold, thereby helping to prevent signal distortion within the amplifier and in the speaker system. The limiter also serves to prevent speaker damage. The limiter function can be engaged by engaging MODE SWITCHES SW2 (for INPUT A) and SW5 (for INPUT B) in the up “ON” position.

LO CUT

MODE SWITCHES SW3, SW4 (for INPUT A) and SW6, SW7 (for INPUT B) provide the options of low frequency filtering starting at the 30Hz and 50Hz frequency ranges and frequencies below those points. These filters “roll off” the lower bass frequency range to help eliminate unwanted “boominess” in the sound system with a -12dB per octave slope. MODE Switch SW4 engages the “LO CUT” filter and Switch SW3 selects between the 30Hz (in the up, “ON” position) and 50Hz (in the down “OFF” position).

INPUT MODE

The INPUT MODE switches select the operating mode of the amplifier. STEREO mode allows the unit to function as a two channel amplifier with each input (INPUT A & INPUT B) routed to a separate amplifier output (OUTPUT A & OUTPUT B), respectively.

PARALLEL mode sums the signals of INPUT A and INPUT B together and routes the combined signal to both OUTPUT A and OUTPUT B.

BRIDGE MODE

This mode allows you to combine the amplifier outputs for more power. MODE SWITCHES #10, 11 and 12 control this function. BRIDGE MODE can provide nearly three times more power output than operating the amp in STEREO mode.

When in BRIDGE MODE, only the controls on INPUT A are functional. INPUT B MODE SWITCH settings have no affect on the operation of the amplifier when in BRIDGE MODE and the volume control for INPUT B should be set all the way down when operating in this mode.

BRIDGE MODE provides a single 4Ω or 8Ω output for connection to an equivalent speaker impedance load. Be aware of the increased power output that BRIDGE MODE provides and be sure that all speakers have appropriate power handling capabilities before making connections otherwise speaker damage may occur. Speaker wiring for BRIDGE MODE is made via the two middle output binding post terminals. See pages 10 and 13 for BRIDGE MODE wiring details.

S-1000, S-2500, S-1500 specifications

Wharfedale, a name synonymous with high-quality audio equipment, offers a compelling lineup of speakers designed to elevate your listening experience. Among their popular models are the S-2500, S-1000, and S-1500, each embodying state-of-the-art technology and features that cater to audiophiles and casual listeners alike.

The Wharfedale S-2500 is a noteworthy floor-standing speaker that combines elegant design with impressive acoustic performance. It features a 6.5-inch woven polypropylene woofer, which delivers deep, controlled bass response, while a 1-inch silk dome tweeter ensures crystal-clear highs. The cabinet is crafted from MDF and finished in a stylish veneer, minimizing resonance and maximizing sound clarity. With a frequency response that spans from 38 Hz to 20 kHz, the S-2500 fills larger rooms with immersive sound, making it an ideal choice for home theater setups and music lovers who seek rich, full-bodied audio.

Next in the lineup is the Wharfedale S-1000, a compact bookshelf speaker that packs an impressive punch despite its smaller form factor. Equipped with a 5-inch bass driver and a 1-inch soft dome tweeter, the S-1000 offers a well-balanced sound profile that excels in both music and dialogue clarity. Its innovative bass-reflex design enhances low-frequency extension, providing surprising depth for its size. The S-1000 is perfect for smaller spaces and can be easily integrated into various setups, whether as part of a multi-room audio system or as standalone units on a shelf.

Lastly, the S-1500 stands out as a versatile option that bridges the gap between the floor-standing S-2500 and the bookshelf S-1000. With its 6.5-inch woofer and 1-inch tweeter, the S-1500 is designed to deliver a dynamic soundstage, making it equally suited for music playback and movie watching. It incorporates a rear-firing bass port, which enhances low-end performance, resulting in a robust and engaging listening experience.

All three models utilize Wharfedale's proprietary technologies, including advanced crossover design that ensures a seamless transition between drivers. This attention to detail in engineering allows for a coherent and immersive soundstage, no matter the listening environment. Whether you're deep into a cinematic experience or enjoying your favorite album, the Wharfedale S-2500, S-1000, and S-1500 speakers deliver exceptional audio performance, blending aesthetics and acoustics to suit a wide range of preferences.
