They have found their way into the world's leading musicians rigs and recording sessions and been featured on thousands of the best selling (and sounding) albums and live performances. Designed to optimize absolute signal integrity and musical performance, the U5 includes many features and sonic excellence unequaled by lesser designs. The U5 is ideal for bass guitar and acoustic instruments, electric guitars, keyboards, synthesizers and low output pickups. Features include state-of-the-art, high input impedance input stage for zero load effect on sensitive pickups and keyboards, 100% discrete, Pure Class A signal amplifiers, practical user features and rugged hardware designed to deliver true high performance audio for many years.\u003c\/p\u003e\n\n\u003cp\u003eThe U5 includes a variable gain Class A preamplifier to boost low level pickup signals and a high level speaker input for capturing the live sound of the instruments amplifier. Six passive tone-EQ curves are also included to enhance a variety of acoustic and electric instruments. A high-cut switch eliminates unwanted acoustic pickup and high frequency noise, while a headphone monitor amp has been included for personal listening. Twin DC coupled Class A output amplifiers drive both low level microphone preamp inputs and high level +4dB inputs for direct to tape recording or processing. The active-to-thru switch selects either the instrument input directly or sends the boosted-equalized signal to the amplifier via the front panel jack. A ground isolation switch eliminates any possible earth loop or AC buzz problems with complete safety.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003ePure Class A, 100% discrete design\u003c\/li\u003e\n\u003cli\u003eSmooth musical detail and sonic excellence\u003c\/li\u003e\n\u003cli\u003eVariable gain preamp to +30dB\u003c\/li\u003e\n\u003cli\u003eDual microphone and line outputs\u003c\/li\u003e\n\u003cli\u003eHi-Z 3,000,000 ohm input impedance\u003c\/li\u003e\n\u003cli\u003eVery low noise -100dB\u003c\/li\u003e\n\u003cli\u003eHigh headroom +30dB\u003c\/li\u003e\n\u003cli\u003eSix tone bank selections\u003c\/li\u003e\n\u003cli\u003eDC coupled Class A output for superior bass\u003c\/li\u003e\n\u003cli\u003eHigh cut switch eliminates noise\u003c\/li\u003e\n\u003cli\u003eLED active signal indicator\u003c\/li\u003e\n\u003cli\u003eHeadphone monitor output jack\u003c\/li\u003e\n\u003cli\u003eLow distortion less than 0.5% THD and IMD\u003c\/li\u003e\n\u003cli\u003eHigh level 400 watt speaker input\u003c\/li\u003e\n\u003cli\u003eActive to thru selector - ground isolation switch\u003c\/li\u003e\n\u003cli\u003e100% discrete power supplies for audio path\u003c\/li\u003e\n\u003cli\u003eInternal toroidal power supply for low noise\u003c\/li\u003e\n\u003cli\u003eLong lasting, stainless steel hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Avalon Design\u003cbr\u003eModel: U5\u003cbr\u003eSKU: I245808-N-0-WHXB\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.

The VT-737SP features a higher-performance microphone input transformer with +48v phantom selection. 2. Instrument DI high source input with jack located on front panel. 3. Balanced line input, discrete high-level Class A. The Class A preamplifier utilizes two cascaded, dual vacuum tube triodes configured with minimum negative feedback. A high gain switch boosts the overall gain of the preamplifier. The four high quality tubes are configured as singled ended anode coupled followers. A passive-variable high pass filter and hard-wire relay bypass completes the input signal conditioning.

The optical attenuator acts as a simple passive level controller. Full dynamic control from soft compression to hard- knee limiting can be achieved with threshold, ratio-compression, attack and release controls plus gain reduction selection on the large VU meter. Special spectral control including de-ess is available with the dual sweep mid EQ to side-chain switch. The EQ section can be flipped pre or post the opto-compressor via a front panel switch for alternate effects and tone shaping. Two VT-737SPs can be linked via a rear panel link cable for stereo tracking.

The high and low frequency bands provide the smooth characteristics of an all passive design, while the dual mid bands include variable frequency and switched Q-width selection. The enhanced range of the mid bands is extended into the high and low bands by the use of X10 frequency multipliers. The bypass switch incorporates a sealed silver relay for the most direct signal path. When the EQ to sidechain is engaged, the high-low EQ remains in the audio path for \"tone enhancement\". The output level control provides a variable control of the overall signal path. The output amplifier utilizes another dual triode vacuum tube driving a 100% discrete, Class A, high-current, balanced and DC coupled low noise output amplifier.\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"color: #000000; font-family: Times; font-size: medium; line-height: normal;\" align=\"left\"\u003e\u003cspan style=\"font-family: Arial, Helvetica, sans-serif; font-size: small;\"\u003e\u003cstrong\u003eAVALON VT-737SP FEATURES\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"color: #000000; font-family: Times; font-size: medium; line-height: normal;\" al\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Avalon Design\u003cbr\u003eModel: VT737SP\u003cbr\u003eSKU: I245807-N-0-WHXE\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.
