14 XONE VF-1 User Guide

Left and Right XLR Outputs

Electronically balanced, wired pin 2 hot (+), pin 3 cold (-) and pin

1 ground. Nominal output level is +4dBu with a massive +22dB

headroom up to a maximum +26dBu drive. The XLR output is

designed to operate with professional balanced equipment such

as speaker processors, mixing consoles and amplifiers.

Left and Right TRS Jack Outputs

These alternative main outputs are impedance balanced meaning

they provide the benefit of cable interference rejection when

connected to balanced equipment inputs. They can also connect

to unbalanced equipment without the need for cable adaptors.

Nominal output level is 0dBu with +22dBu maximum. The jack

outputs provide the switched Mix+Invert function.

Left and Right RCA Phono Outputs

Provide a convenient connection to consumer equipment such as

domestic amplifiers, recorders and DJ mixers. They are

unbalanced with nominal 0dBu level.

Note: You may connect to all the outputs at the same time.

Using the three different connector types you can provide a split

of the output signal to several different destinations.

Left and Right RCA Phono Inputs

VF-1 standard version: Connect stereo line level music sources

such as CD, MD, DAT, drum machines, keyboards or other

instruments. Do not connect turntables which require RIAA

equalisation. Nominal level is 0dBu.

VF-1R (RIAA) version: Only connect turntables which require

RIAA equalisation – line level sources will overload the preamp

and cause severe distortion. Refer also to page 16 (Grounding).

Left and Right TRS Jack Inputs

Balanced, wired tip hot, ring cold, sleeve ground. Nominal level is

0dBu. These provide an alternative input for sources such as

mixers and instruments equipped with jack sockets. They can

work with balanced or unbalanced sources. For unbalanced

sources link the jack ring connection to ground.

Left and Right XLR Inputs

Balanced, wired pin 2 hot, pin 3 cold, pin 1 ground. Nominal

input level is +4dBu. Use these inputs for connection to

professional balanced equipment.

Note: Connect to only one pair of inputs at any time. Do not

attempt to mix sources together by plugging into to more than

one connector type.

Note: Plug into the Left input when operating the VF-1 in mono

mode. In this mode the right input is not used.
