Operating your Zpre
Front Panel Operation
On-Off Button
Press this button once to turn the Zpre on and press it again to turn it off. When the Zpre is turned on, one of the Source LEDs will light up.
Reminder: When the DC trigger is connected, you cannot turn the Zpre on or off from the front panel or remote control handset.
Headphone Jack
The Zpre headphone output is driven by a
Infrared Receiver
Infrared signals from the remote control are received through the infrared receiving eye.
Tone Controls and Indicator
The Bass control boosts and cuts low frequencies +/- 8 dB at 100 Hz. The Treble control boosts and cuts high frequencies +/- 8 dB at 10 kHz.
We recommend judicious use of the tone controls. Maximum bass boost at high levels can overload small speakers.
Balance Control
The balance control adjusts relative left and right volume. If clockwise rotation favors the left channel speaker as you face it, the Right and Left connections between your preamplifier and power amplifier or between your power amplifier and speakers are reversed.
Source Selector Knob and Input Indicators
Rotating the Source knob selects the inputs of the Zpre. Each green Source LED 1 – 4 corresponds to the selected input. The knob is designed to rotate continuously to cycle through the inputs when the knob is turned in either direction.
Volume Control Knob
The Volume control adjusts listening level. If your power amplifier has gain controls, they should be adjusted so the Zpre Volume control knob is between the “11 o’clock” and “1 o’clock” position for most listening. The slight resistance you feel when turning the Volume control knob is created by the motor and gears that enable the volume knob to turn via remote control.
