REAR PANEL & INPUT/OUTPUT CONNECTIONS
1. INPUT SELECT SWITCH
Each SST
2
channel gives the user the option of switching between either balanced input or single ended input.
2. BALANCED INPUT CONNECTOR
This input connector accepts standard XLR (pin 1 = Gnd, pin 2 = Positive, pin 3 = Negartive) or 1/4” Phone plugs
(sleeve = Gnd, tip = Positive, ring = Negative). Use quality, 100% shielded cables with gold plated connectors.
3. SINGLE ENDED INPUT
This input connector
accepts standard ‘RCA’ or ‘Phono’ connectors.
Use quality, 100% shielded cables with
gold plated connectors.
Balanced input Vs Single ended input:
The balanced input requires a balanced pre-amp source. Balanced systems provide noise rejection from external
electrical interference, so cable length can be very long ( 50m or longer ). The single ended or unbalanced input is
provided for pre-amps without balanced output. Single-ended cables should be kept to 20’ (7m) or less. In general
never use longer cables than necessary, never coil excess cable length, and keep signal wires away from AC power
or speaker cables.
4. INPUT SENSITIVITY (GAIN) SWITCH
The optimum gain setting will depend upon the source pre-amp operating level, and or personal preference.
The
29dB
setting is used when the source is
single-ended
, or from a transformer coupled
balanced
source. This is
the
home theatre
setting for
single ended
or un-balanced operation. The
29dB
setting provides the most amplifier
gain and equates to 100w @ 8 ohms output for a 1v input. (noise -110 dB)
The
23dB
setting is used when the sources output is actively
Balanced
. This is the
home theatre
setting for bal-
anced operation Or use this setting wherever less gain is required. The
23dB
setting equates to an output of 100w
@ 8 ohms for 2v input. ( noise -113 dB )
The noise is referenced in dB below rated output. Different input configurations result in slightly different noise read-
ings. The above noise ratings represent minimum readings, actual readings may be better.
5. MODE SWITCH (individual or bridge mode)
The individual setting is for two channel operation. Bridge mode is for mono operation.
6. LEVEL CONTROL (PRO models only)
The level control will attenuate the input signal level from 0dB through -14dB.
7. OUTPUT BINDING POSTS
The
RED
binding post is connected to the
amplifier output
. Connect to this post the (+) terminal on the loudspeaker
for normal (non-bridged or
individual
) operation.
The
BLACK
binding post is connected to
signal ground
. Connect to this post the (-) terminal on the loudspeaker for
normal (non-bridged or
individual
) operation.
The Output binding posts provide three different interconnect options. Combinations may be used when bi-wiring.
Cables should be kept as short as practical and should never be terminated with connectors that may become confused
for AC power connectors. Cables should be dressed away from input and power cables.
Banana plugs
offer a quick disconnect option. Before inserting a banana plug into the binding post be sure to tighten
the post nut to avoid rattling and to provide full insertion of the banana plug. Gold plated locking banana plugs are
available from Bryston.
Spade lugs
provide high contact area and secure fastening. Lugs should be gold plated. Post diameter
is 5/16" (8mm ), lug width 5/8” (16 mm). Gold plated spade lugs are available from Bryston.
Stripped bare wire
up to 3 gage can be inserted through the hole in the binding post and held in place by tightening
the post knob. Additional tightening pressure can be achieved using a
coin
in the slots of the knob. Do not over tighten
or the binding post may become damaged. Note that copper wire is malleable and may require further tightening after
the initial installation.
