TITANIUM HF DRIVER ATTENUATION CONTROL (BR610 & BR615)
On the back of the BR610 and BR615 speaker enclosures there is a jack plate with the HIGH FREQUENCY
ATTENUATION control for the HF Driver. This control will only affect the volume of the HF Driver and does
not affect the 10" or 15" woofers.
The HIGH FREQUENCY ATTENUATION control is another way to increase or decrease the highs coming
from your amp. There are six settings ranging from "0" (full on) to "OFF". If more highs are desired turn
the HF ATTENUATION control UP towards "0" (clockwise), or turn it DOWN towards "OFF" (counter-clock-
wise) if a warmer sound is desired.
Note 1: One thing to consider with the HF Driver volume is which direction the cabinet is facing. Because
the combo amplifier's HF Driver is less that two feet off the ground, the listeners seated in front of the
amplifier may be getting more of the HF Driver volume than you (the player) standing in front of the ampli-
fier. So be conscious of the volume and direction of the HF Driver when adjusting.
Note 2: If you occasionally clip the power amp, the HF driver may make the clipping distortion more
noticable. Turning the HF LEVEL down a few clicks or "OFF" will reduce the unpleasant sound and will
further protect the HF driver from damage.
X-OVER (bi-amping) and BRIDGE modes on the BX1200:
The BX1200 is capable of three different power amp modes, each with different advantages:
1. DUAL MONO mode (standard)
Both the X-OVER and AMP BRIDGE switches are set to "off". Each power amp receives the same mono
signal (unless effects are used in the AMP INSERTS). Speakers can be connected to a single or both
SPK1 and SPK2 output jacks. The balance of volume between the two speaker outputs can be set by the
"1 LO" and "2 HI" POWER AMP controls. This mode can useful when using two different speaker cabi-
nets (such as a 4x10" and 2x10") that have unequal output levels or when using cabinets with low wattage
ratings.
2. X-OVER mode (bi-amping)
The X-OVER switch is "ON" and AMP BRIDGE switch is "off". Power amp 1 (LO freq) handles frequencies
below the CROSSOVER FREQ setting. Power amp 2 (HI freq) handles frequencies above the CROSSOVER
FREQ setting. Subwoofers such as 15" or 18" speakers should be plugged into the "SPK 1" jack. Full
range (or high frequency) enclosures should be plugged into the "SPK 2" jack. The balance of volume
between the two speakers is set by the "1 LO" and "2 HI" POWER AMP controls. The X-OVER mode takes
full advantage of the frequency response of these two different types of speakers.
3. BRIDGE mode (mono, full power into one speaker load)
The AMP BRIDGE switch is "ON" (X-OVER settings are disabled). Plug speakers into the BRIDGE ONLY
jack. DO NOT use SPK 1 or SPK 2 jacks in the BRIDGE mode. This mode is used to get the most power
into one speaker enclosure, or several identical enclosures. Be sure your speaker(s) can handle 1200watts
for 4ohm or 800watts for 8ohm enclosures. If two identical speaker enclosures are used each one will
receive 1/2 the wattage. When using speakers of unequal impedance make sure they can handle the full
wattage.

IMPORTANT! FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING:
WATER AND MOISTURE: Appliance should not be used near water (near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken
so that objects do not fall and liquids are not spilled into the enclosure through openings.
POWER SOURCES: The product should be connected to a power supply only of the type described
in the operating instructions or as marked on the appliance.
GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polar-
ization is not defeated.
POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them, paying particular attention
to cords at plugs, The appliance inlet is the disconnect device. Keep it readily accesable.
SERVICING: The user should not attempt to service the appliance beyond that described in the
operating instructions. All other servicing should be referred to qualified service personnel.
FUSING: If your unit is equipped with a fuse receptacle, replace only with the same type fuse.
Refer to replacement text on the unit for correct fuse type.
SAFETY INSTRUCTIONS (EUROPEAN)
The conductors in the AC power cord are colored in accordance with the following code.

HELPFUL HINTS
1) NO SOUND:
The MUTE function has been inadvertently engaged.
Speakers have been improperly connected.
Effect Loop has been improperly connected.
2) NO HIGH FREQUENCIES:
The BX1200 speaker connections are incorrect when in the X-OVER mode. Tweeters or midrange
drivers have been damaged from too much power.
3) AMP SEEMS VERY SENSITIVE ON INPUT SIGNALS:
The drive control is turned all the way up.
The active switch may need to be turned on.
4) DIR XLR HUM:
Try switching the rear GND LIFT switch IN or OUT.
Try switching to pre DI.
Check for noise from external effects or bad cabling.
5) POOR BASS FROM MULTIPLE ENCLOSURES (BX1200):
Make sure the AMP BRIDGE switch is "OFF" when using SPK1 and SPK2 jacks. The BX1200
speaker connections are incorrect when in the X-OVER mode.
6) FOR MAXIMUM OUTPUT:
To get more output, use multiple speakers or enclosures. Every time you double your speak-
ers, your acoustic output goes up by a factor of four. Load the amplifier down to its lowest
minimum impedance for maximum RMS power.
If you go below the minimum load, your amp will shut off and go into the "protect" mode.
To reset, turn your amp off and connect the recommended load.
SPEAKON
®
cables are recommended for your BX1200 because of their high current capac-
ity. While standard 1/4" speaker cables will work, 12 GA SPEAKON
currents to pass through the cable to extract every watt from your amp.

The BX1200 and BX600 are powerful amplifiers. As with any amplifier, make sure your
speakers are suitable for the available wattage. Driving speakers with too much wattage will
cause them to distort and eventually fail. If distorted sound is coming from the speakers,
reduce the volume until the distortion stops.
