Front Panel
Sophisticated simplicity is a design objective in the development of all
Stewart Audio amplifiers. These amplifiers remain simple and intuitive to
operate even while incorporating some of the most advanced technology
available today.
Power On/Off and Power Level Indicators
The front panel provides visual feed back of the amplifier’s status via
several LED indicators. The power switch is accompanied by a red LED
which illuminates upon turn.
Note:
Upon installation of the CVA-7400/CVA-7800, there will be a turn-on
delay of up to one minute after AC power is applied to the amplifier. This is
a result of the initialization sequence performed by the amplifier’s
High-Frequency Switch Mode Power Supply. Subsequent delays will be
minimal, as long as the CVA-7400/CVA-7800 remains connected to AC
power.
Each channel features two additional LEDs which indicate the level of the
power being produced. Green indicates a signal of –20dB, while Red
indicates that the amplifier is being pushed into clipping. These level indi-
cators are accurate at any load impedance.
Level Controls
A calibrated detented multiple-position input level control has been pro-
vided for each channel. These controls are located behind security covers
and are easily accessible on the front panel of the amplifier. . They operate
in conventional fashion (I.e., full clockwise = maximum level.)

XLR Inputs
Each channel has a female XLR balanced input connector, which may also
be used with unbalanced lines. See
Input Wiring
in the section on
Installation (page 12) for more details. (Note: the XLR input is wired in
parallel with the Barrier Strip input , so that either may be used as a
“through” connection to feed additional amplifiers or other equipment).
5-Way Binding Post Output Connectors
Each channel incorporates a pair of heavy-duty 5-Way Binding Post output
connectors. They will accept bare wire, spade lugs, hook lugs, and single or
dual banana plugs. Additionally the binding posts are situated so that when
the amplifier is configured for bridged operation, one dual banana plug may
be inserted across the terminals. See
Output Wiring
in the section on
Installation (page 13) for more details.
Remote Turn on Feature
When using the CVA-7400/CVA-7800 with a Controller or other
preamplifier with a remote trigger outlet, the amplifier can be turned on
remotely. This unique circuit will allow several amplifiers to be connected
directly to the AC Power Strip. The Remote Turn On input may be
Activated by any five volt signal source.
Removable AC Line Cord
For convenience during the installation, Stewart has included a removable
AC power cord. Please make sure that this cord is connected to a grounded
20 amp un-switched AC outlet.
