CONTROLS AND CONNECTIONS


INSTALLATION
Before making any connections to your high fidelity equipment make sure that all units in the system are switched off and unplugged at the mains.
Mains Connections
The Mains On/Off switch is on the rear panel. Before connecting your QUAD equipment to the AC mains supply check and make sure the voltage marked on the back matches your supply voltage.
Digital Signal Output Connections
Coaxial Output
Venall has one coaxial SPDIF output. Connect an RCA digital interconnect between the digital coaxial out of Venall unit and the required input of your equipment.
Optical Outputs
Vena II has one optical SPDIF output. Connect an optical (TOSLink) interconnect between the digital optical output of Vena II and the required input of your equipment.
Analog Signal Output Connections
Preamplifier Output
Vena II has one pair of unbalanced RCA outputs which can make Vena II operate as a preamplifier.
Connect an RCA cable between the unbalanced pre output of Venal and the unbalanced input of a power amplifier or associated equipment. Interconnection should be low-noise construction and fully screened to minimize hum and noise transmission.
Loudspeaker Outputs
Venall has two sets of loudspeaker outputs. They are independent for right and left stereo amplifier outputs.
Connect the Positive (+) RED terminals of the amplifier to the Positive (+) RED terminals of the loudspeakers. Connect the Negative (-) BLACK terminals similarly. When connecting loudspeakers tighten the terminals securely by hand. Make sure there are no loose strands of wires which could cause short circuits.
Headphone Output
Venall has a stereo 6.3mm(1/4") jack on the front panel for connecting headphones. Connecting headphones mutes the audio signal to the loudspeakers. Vena II headphone output can be set up to 4.5V, users can select suitable output levels to suit their headphones.
WARNING: Listening to music at high volume levels and for extended durations can damage one's hearing. In order to reduce the risk of damage to hearing, one should lower the volume to a safe, comfortable level, and reduce the amount of time listening at high levels. Headsets should comply with EN 50332-2 requirements (for GS certification).
Output Connections
Artera Play

Analog Signal Input Connections
Vena II has two sets of unbalanced RCA inputs for connection to units which do not feature balanced outputs. Both sets are identical.

PHONO Signal Input Connections
Vena II has a PHONO signal input, the PHONO input should only be connected to turntables fitted with MM cartridges
Digital Signal Input Connections
Venall has a variety of digital inputs, which can be connected to most popular digital sources, like the digital output of a CD or DVD player, DAC, PC.
Coaxial Inputs
Venall has a coaxial SPDIF input. Connect an RCA digital interconnect between the digital coaxial out of the source unit to the COAX input of Vena II.
Optical Inputs
Vena II has two optical SPDIF inputs. Connect an optical (TOSlink) interconnect between the digital optical output of the source unit to the OPT1 or OPT2 input on Vena II.
