NSTALLATION
I
The Premier Ten dissipates a significant amount of heat (approximately
20 watts). Accordingly, proper attention should be paid to ventilation.
The unit should be mounted horizontally on a flat hard surface so that
the ventilation holes in the bottom are unobstructed. At least two inches
of clearance should be provided above the unit and the cabinet or shelf
should be open at the back. Vertical installation is not recommended.
To minimize hum pickup, keep the unit well away from the power
amplifier, and route power cords away from input cables.
The Premier Ten requires an ac power line providing between 108 and
125 volts at 50 to 60 Hz. Alternatively, the Premier Ten is optionally
available for operation on 100, 220, or 240 volt power lines.
CONNECTION
AUX/PH, TUNER, CD, TAPE 1, TAPE 2: These high level inputs are
electrically equivalent. They present a 17k ohm load to the source. The
outputs of your tape recorders should be connected to TAPE 1 and
TAPE 2 connectors.
RECORD 1, RECORD 2: The record outputs connect the selected
signal to your tape recorders or external processing loop (eg. equalizer).
This output signal is not affected by the level and balance controls.
Connect to the inputs of your tape recorders or external processors.
OUTPUT: Connect to the input of your amplifier (or crossover in a
bi-amplified system). We recommend the use of an amplifier with an
input impedance of 20k ohms or higher. Since the Premier Ten inverts
phase, it may be necessary to invert the speaker leads to maintain
correct absolute phase. See the section on "Getting the most out of your
Premier Ten" for an explanation of this.
